Routing Protocol Performance with & Without Sybil Attack in MANET

Abstract

MANET is a kind of wireless network which consists of wireless nodes which moves arbitrarily at any direction with relatively low speed. One of the characteristic of such a network is that it doesn’t require any central management authority and it can be build up at any point anywhere anytime. Although this characteristic provide flexibility to mobile nodes but security is not ensured in such kind of attack. Sybil attack is one of the attacks which can harm the MANET network and degrade the performance of the network. Sybil Attack impersonates multiple fake identities to other nodes and may steal the private information while involved in the network. Many researchers consider Sybil attack as susceptible attack to MANET network and proposed detection techniques to the same. In this paper, it is tried to analyze the performance of different MANET routing protocols under Sybil attack, since routing is an important concern of interest as view point of security to such networks. The wide range of routing protocols DSR, DSDV, AODV, TORA and GPSR are analyzed using network simulator 2. The result shows that GPSR protocol showed quite better performance than other protocols.

The Secure Data Sharing for Dynamic Groups with Multi-Owner in Cloud

Abstract

— Generally, Cloud storages are hosted by third parties where the data can be stored and shared providing virtualized pools of storage where people follow the concept of pay per use. The security of data is major concerns at untrusted servers. A basic solution to preserve data privacy is to encrypt data files and then uploading the encrypted data into the cloud. As the cloud servers managed by cloud providers are not completely trusted by users, the data files stored in the cloud may be sensitive and confidential. We provide two fold security to protect data privacy. Firstly, the users are verified by group manager and later the key is provided to the authorized user. Two level of security is provided in order to make changes to the data. We have a backup manager to carry out the process without any abstraction when the manager fails. Hierarchy in system is also established in order to decrease the load from the manager and further distributing the load to its sub system of managers.

A Recursive Time Synchronization Protocol (RTSP) will accurately synchronize all the nodes in a network to a global clock. The proposed technique will take less time when compared to existing path finding technique. KEYWORDS: Time Synchronization, RTSP, Accuracy, Link failure

Implementation of single bit Error detection and Correction using Embedded hamming scheme

Abstract

Multiple bit upsets due to radiation-induced soft errors are a major concern in Nano scale technology nodes. Once such errors occur in the configuration frames of an FPGA device, they permanently affect the functionality of the mapped design. Existing solutions exploit coding techniques with considerably high overhead to protect configuration frames against multiple bit upsets. Our proposed scheme does not require any changes to the FPGA architecture. Experimental results on a Xilinx SPARTAN 3 FPGA device show that the proposed scheme achieves error recovery coverage of 99.30% with only 3% resource occupation while the mean time to repair is comparable with previous scheme. Hamming and embedded hamming schemes are proposed from the literature survey and memory overhead is reduced in order toachieve the successful implementation of error detection and correction codes.

SPARSE VECTOR ALLOCATION BASED ENERGY EFFICIENT MULTIHOP MIMO-AF SYSTEMS

Abstract

In any communication system, the emphasis is on estimating the channel impulse response so as to retrieve the transmitted input signal accurately at the receiver’s end. This work addresses a problem of pilot allocation for joint channel massive multiple-input multiple-output (MIMO) systems. The conventional wireless communications design has major challenges in spectral efficiency and reliability issues. In this work, pilot reduction in Time Frequency Training (TFT) strategy is implemented for orthogonal frequency division multiplexing systems. The pilots are randomly located in a low density manner over the time and frequency domain. To estimate the channels with such low density pilots, we propose  a innovative sparse adaptive measurement vector(SAMV) based channel estimation technique that exploits the common support of the consecutive  channel impulse responses over the certain time duration. At the receiver,Each frame consist of  preamble and subsequent TFT  pilots for MIMO systems where the corresponding time-frequency joint channel estimation method is accurately track the channel variation. Finaly the acquired signal estimates path delay corresponding to the path gains are analysed in frequency domain pilots under the compressive sensing based estimation. Simulation results shows that better performance and higher spectral efficiency than the conventional MIMO-OFDM schemes. Moreover, reduction in pilot observation can maintain better channel estimation accuracy with the aid of CS algorithm and improve the signal recovery probability under low signal-to-noise ratio conditions.

Implementation of low power data encoding techniques for NoC

Abstract

In this paper, a low-power data encoding scheme is proposed. In general, system-on-chip (SoC) based system will have many disadvantages in power-dissipation as well as clock rate wise, such transfer of the data from one system to another system in on-chip. At the same time, a higher operated system does not support the lower operated bus network for data transfer. Unlike SoC, network on- chip (NoC) has so many advantages for data transfer. It has a special feature to transfer the data in on-chip named as transitional encoder. Its operation is based on transitions of input data. The proposed system yields lower dynamic power dissipation due to the reduction of switching activity and coupling switching activity when compared to existing system. Even-though many factors which are based on power dissipation, the dynamic power dissipation is only considerable for reasonable advantage. Besides, the proposed system will be extended up-to inter-link PE communication (data transfer from one PE to other) with help of routers and PEs which are performed by various operations.

EVAPORATIVE COOLER FOR HORTICULTURE PRODUCT

Abstract

This report is about the Evaporative cooler usefull for horticulture product. . The prime objective of this project is to design  the evaporative cooler and then to analyze its main components. Throughout the period between harvesting and consumption, temperature control has been found to be the most important factor in maintaining product quality. Fruits, vegetables and cut flowers are living, respiring tissues separated from their parent plant. Keeping products at their lowest safe temperature (0 C or 32 F for temperate crops or 10-12 C or 50-54 F for chilling sensitive crops) will increase storage life by lowering respiration rate, decreasing sensitivity to ethylene gas and reducing water loss. Reducing the rate of water loss slows the rate of shriveling and wilting, causes of serious postharvest losses. Keeping products too cool can also be a serious problem. Cooling involves heat transfer from produce to a cooling medium such as a source of refrigeration. Heat transfer processes include conduction, convection, radiation and evaporation.Horticultural products are stored at lower temperature because of their highly perishable nature. There are many methods to cool the environment. Hence, preserving these types of foods in their fresh form demands that the chemical, bio-chemical and physiological changes are restricted to a minimum by close control of space temperature and humidity. The high cost involved in developing cold storage or controlled atmosphere storage is a pressing problem in several developing countries. Evaporative cooling is a well-known system to be an efficient and economical means for reducing the temperature and increasing the relative humidity in an enclosure and this effect has been extensively tried for increasing the shelf life of horticultural products in some tropical and subtropical countries.

Abstract

Several routing schemes have been designed in the recent years for wireless sensor networks (WSN). This protocol improves the reliability of data routing in WSN networks. In future WSN networks are expected to carry different traffic such as voice and video as well as data to serve both real and non-real time applications. Therefore, the reliability and quality of the data transmitted to support diverse applications is very important. In this paper, we proposed a new on demand routing protocol i.e. Reliable Fault-Tolerant Multipath (RFTM) routing protocol. RFTM is a multi-objective routing protocol that meets diverse application requirements. Proposed protocol improves both reliability and link quality to determine the number of desired multiple disjoint paths between the sink and source nodes. RFTM routing protocol provides the fault- tolerance and achieves the desired.

Modelling and Analysis of Boron Carbide (B4C) Reinforcement in Aluminium Alloy (A356LM25) Matrix Composite Using CATIA & ANSYS

Abstract

The objective of the present work is the modelling, Static and fatigue analysis of a model made of Aluminium Alloy (A356/LM25) reinforced with 0, 5, 7.5 and 10 weight percentage of Boron Carbide (B4C). The model is designed in CATIA and imported to ANSYS work bench for Static and fatigue analysis. The overall work is divided into three phases. First, modelling the object, second static and fatigue analysis and the third is analyzing the maximum von mises stress values, elastic strain and total deformation in an aluminium alloy composites. From the Ansys results, it was found that the Von mises stresses and elastic strains were increased with non linearity as the percentage increase of Boron Carbide reinforcement in the Aluminium Alloy composite. And the deformation was increased with non linearity at 0%, 5%, 7.5% of B4C. Again a little decrease in the deformation at 10% of B4C. With these results it is concluded that 7.5% B4C is the best composition with Aluminium matrix.

Data Encryption Using Cluster Computing

Abstract

Data encryption is a method where in the original text is converted to an intermediate, encrypted text called cipher text, using a key. The cipher text along with key can be used to get the original text using decryption. The ciphering technique that used in the following paper is AES. It is a type of symmetric cipher that shares the same key between the encoder and decoder. Cluster computing is a technique that creates small computer clusters in order to arrive at a solution to the problem. The strategy utilized here is known as ‘divide and conquer’, with this strategy the given problem domain is broken into smaller parts and each of the smaller problems pose as a separate problem which can be then combined to arrive at a cumulative and generalized solution. With this paper we intend to combine the clustering mechanism with the encrypting and decrypting procedure that can lower the computation time and resources used by it significantly.

A Survey on Black Hole Attacks on AODV Protocol in MANET using Mitigation Algorithm

Abstract

Portable Ad hoc Network (MANET) is an accumulation of versatile hubs that progressively frame a provisional system without base. It has numerous number of utilizations predominantly in the ranges of Sensor Networks (SN), restorative, military and salvage operations. Steering is an imperative part in portable specially appointed systems and it has a few directing conventions, which are influenced from various assaults. Impromptu On interest Distance Vector (AODV) is a standout amongst the most appropriate steering convention for the MANETs and it is more helpless against dark opening assault by the vindictive hubs. A noxious hub that mistakenly sends the RREP (course answer) that it has a most recent course with least bounce check to destination and afterward it drops all the getting parcels. This is called as dark gap assault. On account of various pernicious hubs that cooperate with helpfully, the impact will be more. This kind of assault is known as helpful dark gap assault. In this paper, we have studied and contrast the current arrangements with dark opening assaults on AODV convention and their downsides.

Real-Time CBR Services in Wireless Access Networks: QoS Guarantees

Abstract

In Wireless Networks we need to maintain the Quality of Services (QoS) at different Levels for constant bit rate. These QoS requirements can be successfully met by different scheduling algorithms. Deterministic delay bounds have been focused in most researches whereas the statistical bounds of differentiated real-time services are not concentrated. But in this paper we provide the mathematical analysis of the statistical delay bounds of different levels of Constant Bit Rate (CBR) traffic under the special scheduling algorithm called as First Come First Served with static priority scheduling(P-FCFS). The simulation studies will support the mathematical results. The present study of statistical delay bounds are also compared with the existing deterministic delay bounds of several popular bit rate-based scheduling algorithms. It is observed that the statistical bounds of the scheduling algorithms are much smaller than the deterministic bounds and underlay conservative in the design and analysis of efficient QoS support in wireless access systems.

Flood Mitigation by Structural Method using Optimization Technique

Abstract

Floods occurs in river or water bodies when the flow rate exceeds the capacity of the river channel or water body, particularly at bends or meanders in the waterway. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers. Floods can be managing and control by using structural and non-structural flood mitigation alternatives. By choosing best alternative, floods can be controlled in proper way. Flood mitigation involves the managing and control of flood water movement, such as redirecting flood run-off through flood walls and flood gates, rather than trying to prevent floods together. For selection of best alternative, dynamic programming is to be used for optimization technique. This selection is to be done on the basis of functional, environmental, social, economic and constructability.  Dynamic Programming is decision making tool which gives best decision from the available source.  In case study of Mithi River, Mumbai, catchment area is divided into four sub catchments. Discharge and depth of water for different rainfall intensity varying from 25 mm/hr to 225 mm/hr is determined by using SWMM 5.1 software for different catchment. Depth of flood is determined for that particular catchment by subtracting embankment depth from depth of water. According to the depth of flooding water height of retaining wall for that particular catchment for different rainfall intensity varying from 25 mm/hr to 225 mm/hr is to be decided. Height of retaining wall for catchment 1, 2, 3 and 4 of rainfall intensity 225 mm/hr are 3m, 9m, 15m and 25m respectively. . Keywords- Catchment, Flood Mitigation, Structural alternative, Mithi River, SWMM 5.1, Optimization, Dynamic programming.

EXPERIMENTAL AND ANALYSIS OF WEAR BEHAVIOR AND COUPLED FIELD ANALYSIS OF A355 / 15% SIC ALUMINIUM MATRIX COMPOSITES SLIDING OVER FRICTION MATERIAL

Abstract

The wear behavior of aluminium metal matrix composite (Al MMC) sliding against automobile friction material has been compared with the conventional grey cast iron. The wear tests have been carried out on a pin on disc machine, using pin as brake shoe lining material and discs as A355/15 SiC Al MMC in 30μm, 40μm and 45μm and grey cast iron materials. Pins of 8mm diameter have been machined from a brake shoe lining of a commercial passenger car. The grey cast iron disc has been machined from a brake drum of a commercial passenger car. The Al MMC disc has been manufactured by stir casting technique using A356 aluminium alloy and 15% silicon carbide particles and machined to the required size. The friction and the wear behavior of Al MMC, grey cast iron have been investigated at different sliding velocities, loads and sliding distances. The Finite Element Analysis has done using ANSYS software to finding the temperature distribution and stress on gray cast iron and MMC disc. The present investigation shows that the MMCs have considerable higher wear resistance than conventional grey cast iron while sliding against automobile friction material under identical conditions. A gradual reduction of friction coefficient with increase of applied load is observed for both cast iron and Al MMC materials.
