Analysis of AOMDV and OLSR Routing Protocols Under Levy-Walk Mobility Model and Gauss-Markov Mobility Model for Ad Hoc Networks

摘要

In this paper we have compared AOMDV and OLSR routing protocol using Levy-Walk Mobility Model and Gauss-Markov Mobility Model. OLSR is a proactive, table-driven, link state routing protocol while AOMDV is a reactive routing protocol. Besides eyeing the details of comparing a proactive routing protocol with reactive routing protocol we try to address the circumstantial effect of these mobility models on the routing protocols. Mobility models should symbolize the precise movement of nodes. A thorough investigation of these routing protocols over mobility models which reflect real world scenarios are very important as it affects the overall performance of the network. Part of the results obtained in this paper is in conjugation with [20] thus providing a thorough reference for other research works. Various metrics like packet delivery ratio, average network delay, network throughput, routing overhead and average energy consumption have been considered by varying the mobility speed and the traffic load in the network. Under traffic load scenario the results obtained for AOMDV and OLSR routing protocols contradicted each other for Levy-Walk and Gauss-Markov Mobility Models. But the same could not be said for the two routing protocols when compared under varying mobile speed. We also claim that our paper is the first to compare these two routing protocols with Levy-Walk and Gauss-Markov as the underlying Mobility Models.
