Performance Analysis of Various Ad Hoc Routing Protocols in MANET using Variation in Pause Time and Mobility Speed

A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes that communicates with each other without using any existing infrastructure, access point or centralized controller. In MANET, as nodes moves in and out of the network, the topology of the network changes frequently and thus, routing becomes a challenging task. A variety of routing protocols with varying network conditions are analyzed to find an optimized path from a source to destination. In this article a performance comparison of four popular mobile ad-hoc network routing protocols i.e. Ad hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR), Optimization Link State Routing (OLSR) and Zone Routing Protocol (ZRP) is presented with variable pause time. A network simulator QualNet 6.1. from scalable networks is used to evaluate the performance of these protocols. The performance analysis is based on different network metrics such as Average End to End delay (s), Average Jitter(s), Throughput and Packet delivery ratio.

Study of Performance Variation of AODV Routing Protocol for Various Parameter Patterns using Qualnet Simulator

Ad-hoc On-demand Distance Vector (AODV) is a routing protocol used for Mobile Ad hoc Network (MANET). MANET is formed by mobile nodes connected by multi-hop wireless links without centralized access points or backbone network. Popularity of MANET has been increased because of the availability of license-free wireless communication devices. MANETs can be used for disaster-management, business meetings, military operations, rescue operations, or in a situation where temporary communication network among some nodes is demanded. Routing protocols used in fixed infrastructure networks cannot be efficiently used for mobile ad-hoc networks, so that MANET requires different protocols. This paper presents the analysis of performance of one of the routing protocols used in mobile ad-hoc networks (AODV) under various parameter-patterns with two path loss models, i.e. Two-ray and Free-space model.

Comparative Study of DSR, OLSR and ZRP in MANET under Varying Pause Time and Packet Transmission Rate

MANET is an infrastructure less network which consists of mobile nodes without central administration. It’s routing algorithm should not only be capable of finding the shortest path between the source and destination, but it should also be adaptive, in terms of the changing state of the nodes, the changing load conditions of the network and also the changing state of the environment. In this paper a performance comparison of three popular mobile ad-hoc network routing protocols i.e. Dynamic Source Routing (DSR), Optimization Link State Routing (OLSR) and Zone Routing Protocol (ZRP) is presented with variable pause time and packet transmission rate. A network simulator QualNet 6.1 from scalable networks is used to evaluate the performance of these protocols. The performance analysis is based on different network metrics such as Average End to End delay (s), Average Jitter(s), Throughput and Packet delivery ratio.
