Liao Wenxing, Muqing Wu, Yuewei Wu · 2016
In order to improve the energy efficiency of wireless sensor networks, we present a new energy-efficient algorithm based on multi-dimensional energy space(MES). Our energy-efficient algorithm is easily achieved in software-defined wireless sensor networks (SDWSNs). First of all, we introduce the concept of multi-dimensional energy space based on the residual energy. Then the details of principles of data transmission in our algorithm are introduced. Sensor nodes are firstly deployed in the energy spaces depending on their initial energy. With the increase of energy consumption, sensor nodes with lower residual energy are forced to shift to lower dimensional energy spaces which have different data transmission principles. Communications between different dimensional energy spaces can only apply certain links called “inter-space links”. The simulation results show that our energy-efficient algorithm performs better on balance of energy consumption and network lifetime compared with the typical data transmission algorithms.
