  Abstract

Vehicle to Pedestrian (V2P) is a technology that prevents accidents between pedestrians and vehicles. There exists a tradeoff between the service quality and the overheads to exchange status data among vehicles and pedestrians in providing the V2P services. This may limit the usage of services due to the limitation in battery power of pedestrians’ cellular phones. In this paper, we propose a V2P service which reduces the energy consumption of pedestrian phones without sacrificing the quality of V2P services. The proposed mechanism leverages the Mobile Edge Computing (MEC) servers to avoid the interrelationship between the pedestrian data update intervals and frequency that vehicles receive the pedestrian data. Having the MECs broadcast pedestrian data with a frequency appropriate for the speed of vehicles on behalf of the pedestrians, the cellular phone may inform the data only when the pedestrian moves more than a certain meaningful distance. Furthermore, in order to minimize the unnecessary transmissions from pedestrian phones, the data transmission interval is dynamically adjusted at each cellular phone based on the pedestrian"s context information. Through the simulation, it is shown that the proposed mechanism increases the energy efficiency of the pedestrian cellular phones without degrading the quality of V2P service.
