Abstract:  

 Abstract:  The problem of neighbor position acquisition in vehicular networks is investigated. A realtime protocol called RNP for neighbor position acquisition is proposed. In RNP, time is divided into frames with some time slots. To achieve realtime neighbor position acquisition, RNP adopts an adaptive message transmission strategy. Based on an analytical framework, every parameter of RNP is optimized. Real tracedriven simulations are conducted. Performance results demonstrate that, RNP outperforms other alternative protocols.
