Abstract
This paper evaluates the performance of two different mobile ad-hoc networks (MANET) routing protocols based upon one of the Mobility Model: Manhattan Grid (MG) with varying Speed of the mobile nodes in two different traffic Patterns. We have considered CBR and an Exponential Traffic Pattern (which is based on Exponential distribution). Simulations have been carried out by using Network Simulator Version 2.35 (NS-2) and its associated tools for analysis of results. Comparative analysis of simulation results includes the value of Packet Delivery Ratio (PDR), Throughput and Normalized Routing Load (NRL). It is found that the Exponential Traffic pattern gives better results as comparative to CBR Traffic pattern. A Mobile Ad-Hoc Network (MANET) is a self-configuring network of mobile nodes connected by wireless links, to form an arbitrary topology. The nodes are free to move randomly. Thus the network's wireless topology may be unpredictable and may change rapidly. Each node in the MANET is equipped with a wireless transmitter and receiver, with the aid of which it communicates with the other nodes in its wireless vicinity. The nodes which are not in wireless vicinity, communicate with each other hop by hop following a set of rules (routing protocol) for the hopping sequence to be followed. Routing protocols will need to perform four important functions of determination of network topology,
