Design and Implementation Weights Equation for Optimization DSR Protocol in MANETs Environment

Abstract

A Mobile ad hoc network is a gathering of various data transmission node. The nodes in the MANET are movable. Due to this quality of Mobile ad hoc network, the topology is highly dynamic. There is no fixed infrastructure in this type of network. Any node that wants to transmit the data from the origin node to the sink node in the network, the data has to promote from one node to another node to reach the destination node.MANET routing protocol is divided into proactive routing protocol, reactive routing protocol. First is proactive routing protocolthey are kept routing information; every node keeps routing information to all other nodes in the network.They minimize convergence time but consume higher processor, memory, bandwidth, and battery utilization than reactive protocols. They include Destination-Sequenced Distance-Vector Routing (DSDV),The Wireless Routing Protocol (WRP),The protocol Global State Routing (GSR)The protocol Fisheye State Routing (FSR),andThe Source Tree Adaptive Routing (STAR). Second is reactive routing protocols: they do not need to keep routes among all source-destination pairs, that is why considered better for dynamic topologies.These consists of temporally ordered routing algorithm (TORA); Dynamic source routing (DSR); Destination Sequenced Distance Vector (DSDV); and the ad hoc on Demand Distance Vector(AODV). The purpose of this study was to find the factors that affect the performance of DSR Protocol and design a formula to determine the optimal environment for DSR protocol working.In our work, we have studied the effect of pause time, Number of node, and Transmission range.When we want to study the effect of pause time, we will make the values of the other factors is constant (Number of node, broadcast) and so on. We have applied 50 times for each factor.
