Energy balanced code distribution algorithm of wireless sensor network

The disadvantages of typical sensor network reprogramming protocol is analyzed and an energy balance code distribution algorithm of wireless sensor network (EBCDA) is proposed to improve this problem. Minimum communication distance and energy consumption balance are taken into account in the new algorithm. It chooses minimum weight (W_ij) of communication link according to link distance and residual energy to constitute optimal weight code distribution tree. It improves energy efficiency. Performance analysis and simulation experiments demonstrate that the new algorithm provides higher energy efficiency and longer lifetime.
