ADVICE-LOC: An adaptive vehicle-centric location management scheme for intelligent connected cars

Abstract

With the recent advances and wide availability of heterogeneous wireless access technologies, inter-vehicle communication systems are expected to culminate in the integration of different wireless networks based on such standards as 5G/6G, coupling with multimedia and sensor networks for the next generation of connected and autonomous vehicles. However, the high mobility nature of vehicles poses intrinsic research challenges on the mobility management and the integration of different wireless technologies. Towards this end, in this paper, we propose an ADaptive VehIcle-CEntric LOCation management protocol (ADVICE-LOC) that utilizes the individual mobility projection of each vehicle and estimates the vehicles’ residual time within each access point. Its ultimate objective is to eliminate the network communication’s overhead, while guaranteeing a high packet delivery ratio and low latency rates. The proposed protocol preemptively adjusts the vehicles’ access registration and location updates based on its movement projections. We present our protocol, and we report on its performance evaluation using an extensive set of experiments using SUMO generated vehicles’ mobility. Our results indicate that the proposed DEVICE-LOC protocol succeed significantly in reducing the communication overhead while sustaining high packet delivery ratio when compared to previous studies.
