Management of Smart Vehicular Handovers in Overlapped V2X Networks

Reliable delivery of time-critical safety messages in vehicular networks is essential in intelligent transportation system (ITS) that mainly targets to improve safety on roads. Since the vehicular networks will be inevitably overlapped in metropolitan area, efficient managements of overlapped networks with smart vehicular handovers are necessary in order to mitigate channel interferences and intensive contentions in channel accesses. Currently available standards, including IEEE 802.11p, IEEE 1609, and wireless access in vehicular environment (WAVE) standards, however, are mainly focused on the coordinated multi-channel MAC protocol operations in a single isolated ad hoc network environment without in-depth considerations on the overlapped V2X networks.In this paper, we propose a management scheme for shared control channel and network-initiated smart vehicular handovers in the overlapped V2X networks with slotted TDMA Multichannel MAC (STMC-MAC). The proposed smart handover of vehicles across WAVE basic service set (WBSS) minimized the overhead of registration message exchanges at each WBSS, mitigating packet loss in wireless communication channels. The proposed scheme had been evaluated by implementation on NS-3 network simulator, and the performances of the proposed scheme were measured and analyzed.1
