The Impact of Mobility Speed over Varying Radio Propagation Models Using Routing Protocol in MANET

Abstract

Mobile Ad hoc Network (MANET) is temporary network shaped for a particular function such as transferring data from one node to another that can change locations dynamically without any network architecture. This paper primarily focuses on three propagation models used in mobile ad hoc network. These propagation models are examined and evaluated through changing mobility and traffic parameters. The results of varying radio models are analyzed over DSDV (Destination-Sequenced Distance-Vector) routing protocol. The simulation is carried out using Network Simulator-2 in terms of average network delay, delivery ratio, throughput, and packet drop ratio over mobility parameter speed. The results show that these three models perform differently by using same traffic and mobility factors. The research reveals that the effect of varying mobility speed has more impact on the throughput of all the models especially Shadowing and Two Ray models. However, Shadowing model shows better data sending ratio at higher mobility speed than other models. Shadowing model tends to show longer and consistent average delay and drop more data packets than other models at high mobility speed.
