LSEA: Link Stability and Energy Aware for efficient routing in Mobile Ad Hoc Network

Reactive routing protocols in Mobile Adhoc Networks (MANETs) rely on the discovery process to establish routes between the communication peers. The discovery process employs data flooding to propagate the routing control messages in the network. This process is very costly in terms of packet collisions, network contention and routing overhead, which significantly impacts the network performance. In addition, MANET mobility support is one of the prevalent factors that cause of links and routes breakage. Besides, MANET nodes are battery driven devices that are featured by limited energy lifetime and hardware resources. In this paper, a new routing protocol called Link Stability and Energy Aware (LSEA) is proposed, which is a modified version of Ad-hoc On Demand Distance Vector (AODV) protocol. LSEA employs a novel route discovery process that takes into account the links stability and the nodes residual energy to perform data routing. The simulation results show that LSEA reduces the routing overhead by 17% and increases the network life time by 20%, as compared to the traditional AODV.
