The Impact of Node Velocity on Mobile Adhoc Data Network (MADNET) Performance

Abstract

A Mobile Ad-hoc Data Network (MADNET) is a self-configuring, infrastructure-less network of mobile devices (nodes) where nodes communicate with each other using multi-hop wireless links. Node failures and arbitrary movement of nodes at higher node velocity break the routes and lead to the frequent operation of rebuilding routes that consume lots of the network resources and the energy of nodes. This study, analyses the impact of node velocity on performance of two MADNET Transport protocols i.e. TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) using Uniform Mobility Model. The network performance metrics for analysis in this study are throughput and packet delivery delay. Iperf was used as the network management and performance tool. The result got from the field study shows that the throughput decreases while the delay increases at higher nodal velocities.
