DSR Routing Protocol in Wireless Ad-hoc Networks: Drop Analysis

Abstract

A Mobile Ad Hoc Network (MANET) is a network consisting of a collection of nodes capable of communicating with each other without aid from a network infrastructure. Each node participating in the network works both as host and a router and must therefore is willing to forward packets for other nodes. For this purpose, a routing protocol is needed. The most important characteristics of MANET is the dynamic topology, nodes can change position dynamically therefore a need of a routing protocol that quickly adapts to topology changes. In this paper for experimental purpose, Investigators considered 150m x 150m, 250m x 250m, 350m x 350m, 450m x 450m, 550m x550m, 650m x 650m & 750m x 750m terrain area and illustrate the Drop packet analysis using DSR protocol parameters for wireless network scenario. The Dynamic Source Routing protocol, a simple as well as an efficient routing protocol is designed particularly for use in multi-hop wireless ad hoc networks, allows the network to be entirely self-organizing and self-configuring, without the requirement of any presented network infrastructure or the administration. All aspects of the protocol work entirely on-demand, permitting the routing packet overhead to scale automatically to only which needed to respond to various changes in the different routes currently in use.

A Robust and Efficient Dynamic Network Protocol for a large-scale artificial robotic skin

“…In contrast to the former protocols, they don't explain in [6] how they provide loopfreedom. Source Routing protocols like DSR, as described in [7], store routes in packets, which is insufficient for largescale networks like artificial skins. Dynamic routing protocols always require some bandwidth for route updates.…”

Comparative Analysis of Aodv and DSR to Achieve Group Communication in Manet

“…Requests are discarded if they were processed recently since they are assumed to be duplicates. Here a and b shows that DSR [5] route request and reply. First, the source node looks up its route cache to determine if it already contains a route to the destination [11].If the source finds a valid route to the destination, it uses this route to send its data packets.…”

Congestion Avoidance for Multi-Hop Wireless Network

“…DSR stores the complete path from source to destination including the intermediate nodes through which it reaches the destination in its routing table whereas AODV stores only the next hop node in its routing table. So the information about the path is listed in the packet header by the packet sender to reach its destination [8]. This form of routing is known as source routing.…”
