In order to mitigate the energy consumption of wireless sensor network, a novel depicted algorithm EEGSO （Energy Efficiency based on Glowworm Swarm Optimization） is proposed for energy consumption based on the previous studies. In this algorithm, the energy efficiency ratio and objective optimization function are defined at first, and glowworm swarm optimization algorithm is presented to solve objective function. Then, a simulation with NS2 was conducted to study the performance between EEGSO and other algorithm, and it was deeply studied the key factors of energy efficiency ratio. The result shows that EEGSO algorithm has better adaptability compared other algorithm.
