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 throughputnand 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.

INTRODUCTION
Wireless networks are becoming more and more popular among recent network technologies as compared to the traditional wired network. Wireless networks are connected through the wireless channel.
Generally there are two kinds of wireless networks. The cellular networks and WLANs that have a wired backbone in which the base stations are the boundary nodes and the extended connections between mobile users and the base stations are wireless channels.
The other is wireless ad hoc network, which is an infrastructureless self-configuring network [3] with more than one hop wireless channels in the connection.
This kind of topology is not widely implemented yet, but it is useful in emergency search such as rescue operations, and military applications [2].
