Impact of Channel Fading on the Performance of AODV in Mobile Ad hoc Networks

Abstract

The Mobile Ad hoc network faces the fundamental limitations on its performance due to mobile radio channels. Since, these networks does not trust on any infrastructure to work, not any centralized control on its operation, rather the node itself coordinates and controls the network in cooperation of other devices.The promptness of signal impacts how swiftly the signal level fades as a node moves in space. The objective of this research is to study the performance of Ad hoc On- Demand distance vector Routing (AODV) protocol for mobile ad hoc networks(MANETs) with channel fading. Various experiments have been performed with different variables in different scenarios under free space, two-ray ground and shadowing propagation models. Here the result of the study indicates discrete results of performance of the network.It shows that the AODV protocol has maintaining the routes laboriously in the given environments with severe fading. Additionally, management of radio power so that the packet transmissions are tailored to reach only the desired nodes seems to be a good compromise between interference and coverage.
