ABSTRACT

A Mobile Ad Hoc Network is a collection of mobile wireless nodes connected together to form a dynamic network without the need for any fixed infrastructure. This dynamic and unpredictable nature of MANETs requires multi-path routing. In multipath routing multiple paths are established between a source and destination pair of nodes. Multi-path routing provides several benefits such as fault-tolerance, load balancing etc. Transmission power of nodes plays an important role in MANET communication. Now, let us assume that each node can dynamically control the transmission power it uses independently of other nodes. The objective of this work is to study the behavior and performance of the two multi-path MANET routing protocols with respect to different transmission range/power of individual nodes of the network. We have selected Ad Hoc On-Demand Multi-path Distance Vector (AOMDV) Routing Protocol and Multi-path Dynamic Address Routing (MDART) Protocol for this study. We will analyze the impact of increase in transmission range/power of individual nodes on the performance of these multi-path MANET routing protocols.
