Abstract

A Mobile Ad hoc NETwork (MANET) is considered to be a self-organised network formed by wireless mobile nodes without any existing infrastructures. In the future, it is very likely every person and vehicle will have wireless communication capability in a city environment. The resulting information network can be viewed as a typical MANET with the characteristics of conventional ad hoc networks and Inter-Vehicle Communication (IVC) system with node heterogeneity. Due to various movement behaviors of mobile nodes, space constraints and obstacles effect, the MANET in the city environment can exhibit significantly different characteristic. This paper studies this particular MANET and the characteristics of the mobile nodes in the city environment, and discusses on the solutions for enhancing the routing performance. The city environment is constructed by a novel City-IVC Mobility model, and a typical IVC system, called the RoadLamp-aided IVC system is introduced and compared with the Bus-aided IVC system. The impact on the routing performance in both systems is extensively studied and compared by simulating the conventional protocol AODV
