An RSU coordination scheme for WAVE safety services support

The use of wireless communication technologies to increase road safety is rising within the automobile world. Vehicle to vehicle (V2V) communications is a very promising field but the slow vehicle renewal rate combined with the current world economic crisis turns V2V into a distant scenario. A more viable solution relies on Infrastructure to vehicle communications (I2V) and the use of the wireless access for vehicular environment (WAVE) standard, specifically tailored for delivering safety and multimedia messages in a highly dynamic communication environment. This work-in-progress paper addresses an open issue in a previous presented infrastructure based solution: the beacon coordination between adjacent road side units (RSUs) and also a safety message retransmission mechanism performed by such RSUs.
