MANET Routing Protocols Comparison for Composite Traffic Network

The choice of routing protocols is an important issue in the establishment and design of Ad hoc networks. However, existing routing protocols are based on single traffic source or simple traffic models used in conventional networks like HTTP and video flows. In this paper we focus on choosing routing protocols for network with a composite traffic model that is closer to the real situation. This paper compares two common mobile ad hoc network (MANET) routing protocols, i.e., AODV and TORA in terms of both traffic delay and traffic deliver rate, in networks with different node mobility. Simulation results manifest that TORA outperforms AODV in the traffic deliver rate in all the scenarios. The best traffic deliver rate of TORA is 73.9% in static network. When the nodes in network are static, TORA excels AODV in traffic delay. However, when the nodes move, the traffic delay of AODV improves from 42.60s to 4.56s and is lower than that of TORA.
