QoS Based Power Aware Routing in MANETs

Vinay Rishiwal, S. Verma and S. K. Bajpai

Abstract—In this paper, QoS based power aware routing protocol (Q-PAR) is proposed and evaluated that selects an energy stable QoS constrained end to end path. The selected route is energy stable and satisfies the bandwidth constraint of the application. The protocol Q-PAR is divided in to two phases. In the first route discovery phase, the bandwidth and energy constraints are built in into the DSR route discovery mechanism. In the event of an impending link failure, the second phase, are pair mechanism is invoked to search for an energy stable alternate path locally. Simulation was performed to determine the network lifetime, throughput and end to end delay experienced by packets and for other parameters. The results indicate that Q-PAR is able to discover the required path with lesser overheads, the network lifetime increased by around24-29 % for small networks (20-50 nodes), the packet delivery ratio improved and the packet experienced a low average delay. Moreover the local repair mechanism was able to find an alternate path in most of the cases enhanced the network life time and delayed the repair and reconstruction of the route.
