Optimal Path Selection for AOMDV Routing Protocol with Efficient Energy and Bandwidth in Mobile Ad hoc Network

Abstract

Mobile Ad-hoc Networks (MANETs) are decentralized, self-configuring, and dynamic nature wireless networks which have no fixed infrastructure. These can provide several advantages, however Mobile Ad hoc Networks are energy and bandwidth constrained since nodes operate with limited battery power and limited bandwidth. Due to that, energy and bandwidth are the important parameters in order to design mobile ad-hoc network. How to find the efficient route for MANET routing protocol with efficient energy and bandwidth is the main goal of this thesis. In this paper, during route discovery process, the destination node receive the route request message only if it have enough battery power for transmitting the packet and the primary path for data transmission is selected between source and destination node based on maximal-minimal residual energy and maximum available bandwidth approach. The results of the simulation show that the new proposed protocol, which is Improved AOMDV (IP-AOMDV) can effectively improve the networks’ packets delivery, increase throughput and minimize packet dropping ratio when compared with AOMDV protocol. NS2.35 simulation tool is used to evaluate the performance of both routing protocols.
