Optimal Charging Paths of Wireless Electricity in Wireless Sensor Networks: Fully Charging with One External Stationary Energy Source

摘要

Due to the limited battery power of each sensor in wireless sensor networks (WSN), energy efficiency has been considered seriously as one of the most important factors in designing WSN protocols. Thus, many WSN protocols often sacrifice performance to minimize energy consumption. To mitigate the energy restriction, this paper proposes a wireless electricity (witricity) charging protocol in a WSN with minimizing energy loss of the wireless electricity charging and maximizing a network lifetime of a WSN. To the best of the author's knowledge, this is the first attempt to integrate witricity technology to a WSN with minimizing energy leakage and maximizing network lifetime. Among many different witricity charging models for WSNs, this paper focuses on a fully charging protocol with one external stationary energy source for a stationary wireless sensor network. In a stationary wireless sensor network, sensors are not mobile once they are initially deployed.
