Simulation and Performance Analysis of Reactive Routing Protocols

An ad-hoc network is a collection of two or more devices equipped with wireless communications and having networking capability. The devices in the network can communicate with another node that is immediately within their radio range or one that is outside their range. The intermediate node is used to relay or forward the packet from the source to the destination. An Ad-hoc Network is a self-organizing and self-configuring wireless network. It is a temporary network established without the aid of stand-alone infrastructure. The topology of an ad-hoc network changes dynamically. The topology changes due to departure or arrival of a node. The nodes in mobile ad-hoc network acts as host as well as routers that routes the packets to the destination node. The mobile ad-hoc network is established for a single session and it does not require router of a base station. In this research two Reactive Routing (On-demand) protocols have been studied and compared with each other on various performance factors. The protocols that have to be examined are Dynamic Source Routing (DSR) and Ad-hoc On Demand Distance Vector (AODV). The main part of the research is the energy consumption by these protocols to transfer the data from the source to destination. Various other factors have also been examined in this paper based on which we come to know which protocol can be used according to our requirements and produces better results.
