Abstract

Summary: Communication protocols in vehicular sensor networks (VSNs) in urban areas play an important role in intelligent transport systems applications. Many cross‐layer communication protocol studies are originated from topology‐based algorithms, which is not suitable for the frequently changing computational scenario. In addition, the influence factors that have been considered for VSNs routing are not enough. With these aspects in mind, this paper proposes a multifactor cross‐layer position‐based routing protocol for VSNs to improve reliability and efficiency in message delivery. Considering the complex intersection environment, the algorithm for vehicles selection at intersections (called AVSI) is further proposed, in which comprehensive factors are taken into account including the position and direction of vehicle, the vehicle density, the signal‐to‐noise‐plus‐interference ratio, and the frame error rate in MAC layer. Meanwhile, the dynamic H E L L O _ S T R E A M broadcasting system with the various vehicle speeds is proposed to increase the decisions accuracy. Experimental results in network simulator 3 show the advantage of multifactor cross‐layer position‐based routing protocol over traditional state‐of‐the‐art algorithms in terms of packet delivery ratio, overhead, and the mean end‐to‐end delay. Abstract : In this paper, we have presented a multi‐factor cross‐layer position‐based routing protocol called MCLPR for VSNs to improve reliability and efficiency of message delivery. The protocol takes into account a numbers of factors. In MCLPR protocol, we have proposed AVSI to select the optimal next hop vehicle in intersection environment and AVSNI to select the optimal next hop vehicle in non‐intersection environment, respectively.
