Abstract :

The development of cyber physical frameworks that must support continuous queries of physical situations through wireless sensor systems has picked up thrust recently. Traditional embedded systems, contains standalone devices that can be replaced with a full-fledged Cyber Physical Systems that is designed as a wireless senor network with interacting elements both at the input and output. The cyber-physical systems use query services at regular time intervals accumulate information from the sensor nodes to a centralized base station. Time Division Multiple Access (TDMA), Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA), and Dynamic Conflict-free Query Scheduling (DCQS) etc. which are unsatisfactory for high information rate and continuous application in real time since they give exceedingly variable communication latencies because of their irregular back-off systems and accomplish low throughput under huge load because of intemperate channel discord. Subsequently, for clash free transmission scheduling for constant queries in Wireless Sensor Networks is proposed. The proposed algorithm provides a characteristic tradeoff in the middle of in activity latency and real-time capacity that can adapt its transmission schedule in response to addition, removal and changes in queries dynamically. It provides the ability of adapting to workload changes more efficiently than Time Division Multiple Access with fixed transmissions schedules and it has limited storage requirements which makes it suitable for asset constrained devices. The analysis is validated through NS2 simulations.
