Energy consumption controlling in wireless sensor networks based on power optimality for the main node

The power supply of the nodes in the wireless sensor networks is limited. Because of energy exhaustion, the nodes are easy to get out of order, lose their ability to work and deviate from the network, making the topological structure of the whole networks change. So it needs to design a kind of mechanism which can save energy to maintain stability of the entire networks to the best. In this paper, our contribution is to propose a new mechanism, the power optimality is targeted for the main node. We adopt the genetic algorithms (GA) to optimize the main node. As well, we have analyzed the influence of the controlling frames and the state of receiving on the energy consumption here.
