A comparison of mobile vehicles for data collection and wireless charging

There are two ways to collect data and charge nodes based on mobile vehicles in wireless rechargeable sensor networks (WRSNs). One involves using single function vehicles, data collection vehicles (DCVs), and wireless charging vehicles (WCVs) to collect data and supply energy to sensors. The other involves using dual function vehicles, simultaneous data collection, and wireless charging vehicles (DC-WCVs) to gather data and supply energy to sensors. In order to compare and analyze the performance difference of these two ways, we classify and summarize related works in the field of mobile vehicles in sensor networks. Furthermore, we validate the network performance differences between the two ways through experimental verification and observe that the network lifetime and collected data amount are higher in networks using single function vehicles. The tour length of dual function vehicles is smaller in networks using dual function vehicles. Finally, we propose suitable vehicles to collect data and charge nodes for different optimization objectives. © 2019 Totem Publisher, Inc. All rights reserved.
