Some Ad Hoc Network Characteristics Effects on the Performance of On-Demand Routing Protocols

AMobile Ad-Hoc Network (MANET) is a collection of wireless nodes that can be setup dynamically anywhere and anytime without using any pre-existing network infrastructure. Each node can communicate with another node that is immediately within their radio range. Traditionally Ad-Hoc routing protocols are typically used to deal with the dynamic nature of these networks and can survive rapid changes in the network topology. These protocols typically suffer from a number of shortcomings, such as high routing overhead and limited scalability. This motivates the work presented in this paper, which provides a comparison of AODV and DSR protocols inMobile Ad-Hoc network. Our experimental results show that the routing path is changed by using the Critical Transmission Range. A comparison analysis of the topology changes, transmission range and hop count is presented.
