摘　　要：为解决无线传感器网络的能耗问题.提出了一种刻画能耗的新算法EEGSO(Energy Efficiency based on Glowworm Swarm Optimization).首先给出有效转发能效比定义和目标优化函数,同时通过萤火虫群优化算法实现对目标函数的求解.最后,利用NS2进行仿真实验,对比分析了EEGSO算法与其它算法之间的性能状况,并深入研究了影响有效转发能效比的关键因素.研究结果表明:相比于其它算法,EEGSO算法具有较好的适应性.In order to mitigate the energy consumption of wireless sensor network, a novel depicted algorithm EEGSO(Energy Efficiency based on Glowworm Swarm Optimization) was 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, compared with other algorithm,EEGSO algorithm has better adaptability.
