2 May 2016 | | Abstract: | Motivated by alleviating CO$_2$ pollution, Electric Vehicle (EV) based
applications have recently received wide interests from both commercial and
research communities by using electric energy instead of traditional fuel
energy. Although EVs are inherently with limited travelling distance, such
limitation could be overcome by deploying public Charging Stations (CSs) to
recharge EVs battery during their journeys. In this paper we propose a novel
communication framework for on-the-move EV charging scenario, based on the
Publish/Subscribe (P/S) mechanism for disseminating necessary CS information to
EVs, in order for them to make optimized decisions on where to charge. A core
part of our communication framework is the utilization of Road Side Units
(RSUs) to bridge the information flow from CSs to EVs, which has been regarded
as a type of cost-efficient communication infrastructure. Under this design, we
introduce two complementary communication modes of signalling protocols, namely
Push and Pull Modes, in order to enable the required information dissemination
operation. Both analysis and simulation show the advantage of Pull Mode, in
which the information is cached at RSUs to support asynchronous communication.
We further propose a remote reservation service based on the Pull Mode, such
that the CS-selection decision making can utilize the knowledge of EVs’
charging reservation, as published from EVs through RSUs to CSs. Results show
that both the performance at CS and EV sides are further improved based on
using this anticipated information. | | Source: | arXiv, 1605.0434 | | Services: | Forum | Review | PDF | Favorites | |
