A routing protocol for extend network lifetime through the Residual Battery and Link Stability in MANET

MANET(Mobile Ad-hoc Network) which does not use a wired network and base station system is composed of a group of mobile and wireless nodes. There are various types of restrictions. The main restriction is the frequent change of network topology and confined energy of the batteries. In MANET, route is only maintained during short time and mobile nodes are connected with each others having limited battery capacity. Namely, it is very important that we consider Link Stability and Battery Capacity at the same time in MANET. In recent years, much research has been tinder taken to not only improve the energy efficiency but also to lengthen the network lifetime. In this paper, we propose EBL(A Routing Protocol for Extend network life time through the Residual Battery and Link Stability in MANET). The EBL considers distance among neighbor nodes, Residual Battery Capacity and Link Stability. The EBL is based on AODV(Ad-hoc On-demand Distance Vector Routing). We use ns-2 for simulation. This simulation result shows EBL is able to extend network lifetime by reducing power consumption and distributing traffic load centralized into special node.
