摘要

Uneven energy distribution, which severely influences network lifetime, is a prevailing problem existing in many routing protocols for wireless sensor networks. To solve this problem, a distributed multiple attribute-based energy-balance routing (DMAE) is proposed. Through introducing load prediction mechanism and total transmission energy cost (TEC), we define parameters like residual energy, comprehensive load and TEC as attributes that are employed to establish a multiple-attribute decision making model. Weights of these attributes are calculated by using relative entropy based on information of node's forward neighbor table. Each node selects the optimal forward neighbor to relay packets according to the decision making model, which can effectively balance energy consumption of all nodes. Simulation results show that by comparing with MTE (minimum transmitted energy), EAR (energy-aware routing), DEBR (distributed energy balanced routing), DMAE has better energy-balancing effect and energy efficiency, which prolongs network lifetime.
