On the Selection of Optimum QoS Bounds for Mobile IP Enabled VANET through Realistic City Scenario

The emergence of DSRC 802.11p in VANET (Vehicular Adhoc Network) has resulted in the evolution of Intelligent Transport System (ITS). However, one of the major challenges in the success of VANET is the robust and reliable implementation through rapid vehicle movement and hostile channel conditions. Mobile IP can be considered as one of the most promising technologies to address the challenge of uninterrupted services in spite of rapid movement. In this work, a Mobile IP enabled scenario has been proposed and the hostile channel conditions have been modeled using Rayleigh fading distribution. The optimum QoS bounds have been obtained through extensive simulations by varying the queue size and application traffic type. Due to the quick handoff in Mobile IP, there is crucial need of selection of appropriate queue size responsible for accommodating data packets. Considering all these factors, this paper emphasizes on the selection of most suitable application traffic along with appropriate queue size even under realistic channel conditions for Mobile IP enabled City Scenario.
