Abstract:
The new generation of WSNs has no more energy limitation problem. They could be recharged through wireless charging, which is more relaiable than energy harvesting techniques. Moreover, recent advances in power transfer to simultaneous multiple devices improved scalability problem in Wireless Rechargeable Sensor Networks (WRSNs). In this thesis, we formed virtual nodes by clustering sensor nodes in minimum possible clusters. Then, virtual nodes were scheduled according to their lifetime in a TSP-based manner. In synchronization phase, the energy level of the nodes was calculated to make them send their request on their scheduled charging turn. So, on received requests, the mobile charger could charge proper nodes according to charging table and constructed service pool. The proposed charging protocol can reduce both evaluation parameters (traveling distance and charging delay) by about 10% and 40% respectively.
