Enhancement Of 802.11 Modules In Ns-2 For Wireless Access On Vehicular Environments And Performance Evaluation

This paper designs and develops the simulation program based on ns-2 for the multi-channel operation of the WAVE mode which is defined to enable communication among high-speed vehicles or between a vehicle and a roadside infrastructure network. The ns-2, the most popular simulation tool for networking research, supports the original 802.11 MAC and PHY, and some researchers contribute 802.11e, 802.11-extension modules to ns-2. However, the wireless MAC module utilizing the multi-channel operation for the WAVE has not been included until now. In this paper, we explain the newly-designed multi-channel simulation program based on ns-2 and show the verification and performance results.
