Analytical Simulations for Proactive, Reactive and Position based Routing Protocols using OMNeT++ via INet Framework

Abstract

Vehicular ad-hoc networks VANETs has become one of the great research topics related to automotive industry, as they are the suitable way to describe the real scenarios of the car movement through our daily life. Routing protocols used in the network description of a vehicular ad-hoc network are to balance between the responsiveness of the network to the rapid change of the topology and bandwidth efficiency. Different approaches for routing protocols are introduced to address the routing strategies to be followed in the constructed vehicular ad-hoc network considering its perspective of the routing algorithm to be followed. Each approach is consists of different routing protocols that inherits the main theme of the parent approach. Evaluating the measurements for each approach is very important for the developer of the network through network simulation prior to the expensive direct implementation of the vehicular ad-hoc networks. In this paper, we will discuss three main routing approaches: reactive, proactive and position based routing protocols, discussing the main theme for each approach followed by analytical simulations for three different protocols representing the three approaches. Ad-hoc on demand vector AODV representing the reactive approach, destination-sequenced distance vector DSDV representing the proactive approach and greedy perimeter stateless routing GPSR representing the position based approach.
