Fault Tolerance QoS Routing Protocol for MANETs
M. L. Ravi Chandra, P. Chandra Sekhar Reddy · 2016
A Mobile Ad Hoc networks is a dynamic environment which due to frequently mobile wireless nodes experiences Communication failures due to network partitioning, and nodes failures exhibiting different faulty actions temporary or long lasting arising out of glitches related to hardware or software. As the mobile nodes are mostly resource constrained, in case of faulty nodes packets forwarding could be lead to further complications. Hence in designing a robust mobile ad hoc network fault tolerance plays a major role. Due to the presence of faulty nodes, the Performance of routing degrades and the reason for the faulty nodes has to be identified to address routing by exploring network redundancies. In our previous work[13],we devised Genetic Algorithm(GA) based Energy efficient QoS routing (GAEEQR) protocol. As extension of previous work, we devised protocol called Fault Tolerance QoS Routing Protocol, which has capability to send the data with an alternative route when route break occurs. This protocol gives the better results than GAEEQR in terms of delay, packet delivery ratio, and throughput and energy consumption.
