STUDY & PERFORMANCE ANALYSIS OF HOMOLOGOUS ROUTING PROTOCOLS OF WIRELESS INFRASTRUCTURE LESS NETWORK
A Wireless Infrastructure less Network represents a system of wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary network topologies, allowing people and devices to seamlessly internetwork in areas without any preexisting communication infrastructure. These networks are also known as Mobile Ad hoc Networks (MANET). To this end, mobile nodes must cooperate to provide the routing service. Routing in mobile environments is challenging due to the constraints existing on the resources (transmission bandwidth, CPU time, and battery power) and the required ability of the protocol to effectively track topological changes.An ad hoc network has certain characteristics, which imposes new demands on the routing protocol. The most important characteristic is dynamic network topology, which is consequence of node mobility. Nodes can change position quite frequently, which means we need a routing protocol that quickly adapts to topology changes. Many Routing protocols have been developed for accomplishing this task. In this thesis we have simulated, analyzed and compared three homologous ad-hoc routing protocols DSDV, DYMO and ZRP at different scenarios. We have used Qualnet version 5.0.2 Simulator for the simulation of these routing protocols at two different channel frequency and at two different Physical radio model and also the performance of these protocols are analyzed using Random Way Point Mobility Model and compared them for throughput, average end to end delay, Average jitter, Mobility, Number of broadcast and unicast packets transmitted and received, Signal Received and forwarded to MAC layer.
