The current algorithm is mostly focused on the power loss at the node transmission, rather than the impact that may have in residual energy on network lifetime. As a result, the network node failed to achieve an effective balance in energy consumption, leading to premature death of a number of nodes, and thus unable to better extend the network lifetime. This paper is designed to take on the parameters of energy consumption and residual energy at node transmission, while giving the definition on the cost function along the transmission link. Meanwhile, a distributed topology control algorithm (EBDTCA) that is based on node energy balance was presented with theoretical analysis. With the help of this algorithm, the network topology may be optimized in reference to real-time dynamic of the node content can. Furthermore, only the local topology information is required to be able to achieve the global topology optimization, as a kind of lightweight topology control algorithm. Simulation results showed that the algorithm could avoid excessive consumption of energy at the bottleneck node. In the case of random distribution, the network survival was extended by app. 20%, relative to the classic LMST and LSP algorithms.
