performance evaluation of a hybrid adaptive service discovery protocol for next generation heterogeneous vehicular networks (hvns)
Recently, vehicle networks are gaining lots of interest from the research community. In order to provide efficient and pervasive road communication, Heterogeneous Vehicular Networks (HVN) are considered as a promising solution. HVNs have unique characteristics and face challenging problems. Consequently, it is hard to use the traditional mechanisms and protocols in this type of networks. service discovery is a very challenging problem for HVNs based applications. Furthermore, to the best of our knowledge, very little work has been done to deal with the service discovery problem in HVNs. Due to the heterogeneity of the vehicular network and the high mobility and density of vehicles, traditional discovery techniques do not perform well. To solve this problem, we first propose a new architecture for Next Generation Heterogeneous Vehicular Networks, then we propose a novel class of service discovery protocol that permits to vehicles to discover services through the heterogeneous wireless network. Our hybrid proposed technique combines both proactive and reactive discovery approaches. It is also adaptive because it adapts to the vehicular network conditions in order to permit efficient discovery in terms of low overhead, and high success rate. We present extensive simulation results to evaluate the performance of our scheme.
