Implementation and performance evaluation of AODV in Wireless Mesh Networks using NS-3

Wireless Mesh Networks (WMNs) are a radio-based network technology that has gained considerable importance in network research community. It is a multi-hop wireless access network where nodes can act both as a host as well as a router. One of the factors that influence the performance of WMNs is the underlying routing protocol used. Since implementation of wireless routing protocols in a real test bed is difficult, hence, simulation environment is being considered for performance evaluation of a routing protocol in a wireless scenario. Recently, a new network simulator called NS-3, which is in its developing stage, demands a great potential (as claimed by the developers group) for performance analysis of different routing protocols. In this paper, we aim to implement and analyze the performance of Ad hoc On-Demand Distance Vector (AODV) routing protocol in NS-3, which is one of the candidate routing protocol proposed by IETF group for WMNs. For this, we have implemented AODV in NS-3.6 and extensive simulations have been carried out for calculation of Throughput, Packet Delivery Ratio (PDR), and Normalized Routing Overhead (NRO).
