Performance evaluation of the manhattan mobility model in vehicular ad-hoc networks for high mobility vehicle

摘要

Vehicular ad-hoc network is a part of MANET in which the road topology and traffic regulations must take into considerations for the movement factors. VANET is supported by fixed infrastructure in a crucial points which can help with a few services, such as a warning messages. It also can connect the network to stationary network. The Manhattan mobility model is a mobility model that can generate the map pattern of the Manhattan city, which resembles a complex traffic. In this model, there is a Traffic Light Model (TLM) algorithm that can control the mobile node movement in intersection. In this work, we evaluate the implementation based on NS-2.34 for an application to control the packet data sending. VanetMobiSim 1.1 is used as an application to generate the movement model from the Manhattan mobility model. The simulation result shows that the end to end delay depends on the node congestion, average hop in one route and congestion window. The results shows that the Manhattan mobility model can reach 140 ms end to end delay on 190 m wireless range. The packet delivery ratio of Manhattan mobility model can reach the value of between 90% – 99% in 190 m wireless range. The average number of hop is between 2.5 – 5 in the 150 m wireless range. Using this model, the throughput which can be achieved is almost 12 kbps.
