Data and Energy Integrated Wireless Networking

With the wireless communication being more various in the future, it is becoming challenging to prolong the lifetime of many battery powered devices, since frequently replacing their batteries is a cumbersome job. An hybrid access point (H-AP) is capable of simultaneously operating wireless data transfer (WDT) and wireless energy transfer (WET) by exploiting the radio frequency (RF) signals. By jointly considering both the mobility of the user and the popularity of the sites, we focus on the design of the H-AP’s deployment scheme. Specifically, a mobility model of the grid based city streets is exploited for characterizing the users’ movements. Based on this mobility model, the impact of the deployment site’s popularity on the WDT and WET efficiencies is firstly analyzed. Then, an H-AP deployment scheme for striking a balance between the WIT and the WET efficiencies is proposed, which is regarded as the B-deployment scheme. The simulation results demonstrate that the B-deployment scheme is more flexible for satisfying diverse requirement of the WDT and WET efficiencies.
