Mobility Models for Vehicular Ad-hoc Network Simulation

Evaluation of Mobility Models For Vehicular Ad-Hoc Network Simulations

There is a growing interest in deployment and evaluation of routing protocols for Vehicular Ad-Hoc Wireless Networks (VANETs) in urban contexts. The mobility model of nodes is one of the most important factors that impacts the evaluation of any wireless ad-hoc routing protocol using simulations. In this paper we make the case that the state-of-the-art simulation techniques do not effectively mo...

Improving Vehicular Ad-Hoc Network Stability Using Meta-Heuristic Algorithms

Vehicular ad-hoc network (VANET) is an important component of intelligent transportation systems, in which vehicles are equipped with on-board computing and communication devices which enable vehicle-to-vehicle communication. Consequently, with regard to larger communication due to the greater number of vehicles, stability of connectivity would be a challenging problem. Clustering technique as ...

Towards Realistic Mobility Models for Vehicular Ad-hoc Networks

In performance studies of vehicular ad hoc networks, the underlying mobility model plays a major role. In this paper, we investigate the influence of three mobility models on the performance of ad hoc network routing protocols (AODV and GPSR). As a benchmark, we use the popular random waypoint mobility model. Our second model is based on a vehicular traffic simulator that we proposed in earlier...

A Survey on Mobility Models for Vehicular Ad Hoc Networks

Vehicular networking is an emerging area of interest in the wireless networking community as well as in the transportation research community. Vehicular ad hoc networks (vanet) are distributed, self-organizing communication networks which progressed from traveling vehicles, and are thus characterized by very high speeds and limited degrees of freedom in node (vehicle) movement patterns. Differe...
