Abstract: Mobile ad hoc network is a collection of mobile nodes communicating through wireless channels without any existing network infrastructure or centralized administration. Because of the limited transmission range of wireless network interfaces, multiple "hops" may be needed to exchange data across the network. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. The primary goal of such an ad hoc network routing protocol is to find an efficient route establishment between a pair of nodes so that messages may be delivered in a timely manner. Route construction should be done with a minimum of overhead and bandwidth consumption. This study examines two on demand routing protocols for mobile ad hoc networks based on manhattan grid mobility model-the Dynamic Source Routing (DSR), Ad hoc On-demand Distance Vector routing (AODV) and evaluates both protocols based on packet delivery fraction, normalized routing load, average delay and normalized medium access load by varying number of nodes, speed and connection rate.
