Distributed Dynamic Power Allocation Strategy Based on Energy Balance in Wireless Sensor Networks for Smart Grid

The characteristics of wireless sensor networks can solve many problems in smart grid construction. The power allocation strategy can effectively improve the energy efficiency of wireless sensor networks, but the static strategy will lead to unbalanced network energy consumption. So we construct a function of the energy condition of the reaction node. The transmission power of nodes is changed dynamically through the exchanging of information between neighbor nodes. And a distributed dynamic power allocation strategy based on energy balance is proposed. Simulation results show that it can effectively prolong the overall survival time of the network. This method can be used in a power system private network.
