摘要：
In this paper, an energy-efficient routing algorithm with joint distributed routing and centralized scheduling for software-defined wireless sensor networks (SDWSNs) is proposed to balance energy efficiency and capacity efficiency. The proposed least energy difference based routing algorithm called LEDRA is composed of two major components that are neighbor type determination criteria and relay selection criteria. Sensor nodes execute LEDRA based on the prior criteria in a distributed routing way. For given sensor and sink node pair, the controller executes LEDRA based on the latter criteria through centralized scheduling and updates the routing considering energy efficiency and interference mitigation into the flow tables stored at the sensor nodes. Simulation results show that the proposed LEDRA is able to reduce energy consumption while improve capacity efficiency by mitigating interference.
