Efficient Coordination among Electrical Vehicles: An IoT-Assisted Approach

Higher refueling time of the Electric-Vehicles (EVs) is one of the major concerns in their wide-spread use for transportation. A well-planned charge scheduling of the EVs, hence, is extremely important for proper utilization of the limited charging infrastructure and also limit the size of the waiting queue in the Charging Stations (CSs). Almost all the existing works on this topic are theoretical and assume the availability of global data of the EVs and the CSs. In this work, we take an endeavor to derive a practically useful solution to this problem through efficient EV-CS coordination. In particular, we perceive the EVs and the CSs to be connected with each other through a Low-Power Wide Area Network (LPWAN) and propose to achieve dynamic EV-CS coordination through the use of Concurrent-Transmission (CT) based mechanism. Through extensive simulation and testbed based studies we demonstrate how the goal can be fruitfully achieved in a quite scalable fashion despite the requirement of a very wide area coverage and active participation of an enormous number of EVs and CSs.
