An Efficient and Reliable Data Gathering Protocol Based on RSU Identification

Vehicular Ad hoc Networks (VANETs) can act as an essential platform for providing various types of safety and non-safety applications by collecting the data sensed by the vehicles during their journey. To collect data in an efficient manner exclusive of network congestion is a very challenging task. In this paper, an efficient data gathering protocol based on Road side unit (RSU) identification approach is proposed for collecting the essential data sensed by the vehicle during their journey in an efficient manner without network congestion. The proposed protocol is able to reduce the communication overhead and average delay and capable of increasing the packet delivery ratio. Moreover, the proposed protocol is compared with the RSU activated data gathering protocol based on beacon broadcast. With the help of simulation results it has been identified that the proposed data gathering protocol considerably improves the efficiency of data collection as compared to RSU activated data gathering protocol based on beacon broadcast on the basis of communication overhead, average delay and packet delivery ratio.
