Abstract

Unlike a cellular network, MANET(Mobile Ad-hoc Networks) is constructed only by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment, and node mobility, more power-efficient and reliable routing protocols are needed. Namely, it is very important that we consider Residual Battery Capacity and also Link Stability at the same time in MANET. Accordingly, this paper proposes RPTnE(A Routing Protocol for Throughput Enhancement and Extend Network Lifetime in MANET). The RPTnE considers Residual Battery Capacity and Link Stability. The RPTnE is based on AODV(Ad-hoc On-demand Distance Vector Routing). We use ns-2 for simulation. This simulation result shows that RPTnE is able to enhance throughput and extend network lifetime through the reduction of power consumption and distribution of traffic load that is centralized into special node.
