A Novel Link Stability and Energy Aware Routing with Tradeoff Strategy in Mobile Ad Hoc Networks

—Mobile ad hoc networks (MANETs) are selforganizing, rapidly deployable networks without any fixed infrastructure. In MANETs, mobile terminals can move freely, which cause frequent link breakage. Due to the dynamic nature of the network, finding a stable route for transmitting data is a challenging task. In order to adapt to the topological changes and provide some quality of service (QoS), this paper propose a novel link stability and energy aware routing algorithm with tradeoff strategy, and implement it on Ad Hoc On-demand Distance Vector Routing Protocol (AODV), namely NLSEAAODV. The new protocol sets up routes with high stability in route discovery based on link stability and node energy information, and predict the breaking link in route maintenance. Besides, the routing takes a route stability-hop count tradeoff strategy to select routes with high stability and low hop count. Simulation results show that the new protocol has a better overall performance than original AODV protocol, which improved the network utilization greatly.
