Design and performance analysis of high reliability-optimal routing protocol for mobile wireless multimedia sensor networks

Designing of Wireless Multimedia Sensor Network (WMSN) routing protocols limited by conventional sensor network protocols. They have been designed for scalar data such as sensor data; which is small in size compared to multimedia data. The addressed challenges were the motivation to design mobile reliable routing protocol based on greedy routing structure. In this paper, we propose a new routing protocol for greedy forwarding based on throughput energy aware multi-path routing protocol(GFTEM), which is based on selection of next hop node that has the highest throughput and closer to destination node. GFTEM performance is seen and compared against Ad hoc on-demand distance vector routing protocol (AODV), Dynamic MANET on-demand routing protocol(DYMO) and greedy perimeter stateless routing for wireless networks (GPSR). The OMNET++ simulator has been used to study the behavior of the protocols in terms of end-to-end delay, packet error rate and residual energy. The protocols has been tested under various sensor node speed and the simulations demonstrate that GFTEM has better end-to-end delay, packet loss ratio, with good energy efficiency compared to GPSR, AODV, DYMO routing protocols.
