Abstract
The inevitable combination of Software Defined Networking (SDN) and Wireless Rechargeable Sensor Network (WRSN), or the so called evolution from WRSN to Software Defined WRSN (SDWRSN), is a gradual process. Hybrid SDWRSN, where software defined devices and traditional devices coexist, will last for a long time. Hybrid SDWRSN brings new challenges as well as opportunities for energy saving issue, which is still a key problem considering that the wireless chargers are also exhaustible, especially in some rigid environment out of the mains supply. Numerous energy saving schemes for Wireless Sensor Networks (WSNs), or even some works for WRSNs, are no longer suitable for the new features of hybrid SDWRSNs. Consequently, we derive a mathematical optimization model for the energy efficiency problem in hybrid SDWRSNs. Based on the model, an Energy-saving Traffic Scheduling (ETS) algorithm is proposed to achieve better energy efficiency. The simulation results show that comparing with traditional Minimum Transmission Energy (MTE) protocol, ETS can substantially improve the energy efficiency in hybrid SDWRSNs for up to 20–40%.
