Abstract :

Mobile Ad-hoc Network (MANET) is self-organizing and independent infrastructures, dynamic network consisting of a collection of wireless mobile nodes that communicate with each other without the use of any centralized authority. This makes them an ideal choice for communication and information sharing. In MANETs nodes are vulnerable to malicious entities that aim to tamper and analyze data and traffic analysis by eavesdropping or attacking routing protocols. Also, limited resource is a problem in MANETs, where each node experiences under an energy constraint problem. Since MANETs complex routing and stringent channel resource constraints impose strict limits on the system capacity. However, existing anonymous routing protocols generate a significantly high cost, which is resource constraint problem in MANETs. It use anonymous routing protocols that hide node identities and routes from outside observers in order to provide anonymity protection and propose an Anonymous Location-based Efficient Routing protocol (ALERT). ALERT initially it partitions the network field dynamically in to separate zones and randomly chooses nodes in zones as intermediate relay nodes, ensuring a non-traceable anonymous route. In this protocol the data initiator/receiver among many initiators/receivers is hidden. Thus, ALERT offers anonymity protection to sources, destinations, and routes. It also provides effective solution to counter inter- section and timing attacks.  Experimental results exhibit consistency with the theoretical analysis, and show that ALERT achieves better route anonymity protection and lower cost compared to other anonymous routing protocols. Many anonymity routing algorithms are based on the geographic routing protocol (e.g. Greedy Perimeter Stateless Routing (GPSR)) that greedily forwards a packet to the node closest to the destination. ALERT provides high level security to sources, routes and destinations. At the end we compare ALERT with other protocols in terms of efficiency and cost.
