An efficient environmental model considering environmental factor for V2I application services

Recent development in communication of wireless communication for automobile industry have aided the growth of ITS (Intelligent Transport System) which solves numerous vehicular mobility concerns like traffic congestion, accidental mishap etc. VANET (Vehicular Ad-hoc Network) a characteristic class of MANET (Mobile ad-hoc Network) which is a fundamental element of Intelligent Transport System in which the moving vehicles inter connected and communicates with each other remotely. Wireless technologies play an important part in assisting both Vehicle to Infrastructure (V2I) and Vehicle to Vehicle (V2V) correspondence in VANET. The existing scheduling technique does not consider the environmental factor which affects the throughput performance and increases packet drop rate which intern incur packet delay. Here in this work the author propose a RHU (Rural, Highway and Urban) environment model considering the environmental factor. The efficient environmental model algorithm is incorporated into slotted aloha in IEEE 802.11p MAC protocols which aided as a spine for assisting both safety application and non-Safety applications. The 802.11p also known as DSRC/WAVE technologies support low latency V2I communication. Experiments are conducted for collision and throughput efficiency. The experimental result shows the proposed environmental model impact on collision and throughput efficiency for varied environment and thus improving QoS for VANET application.
