能量采集型无线传感器网络的高能效路由算法
A High Energy Utilization Routing Algorithm in Energy-harvesting Wireless Sensor Networks
摘要
Abstract
In energy-harvesting wireless sensor networks, sensor nodes can harness environmental energy to power the nodes. However, energy is still very valuable, so how to optimize routing protocol to improve energy utilization and maximize network lifetime is still a problem worthy of study. In order to solve the en-ergy efficient routing, an energy efficient routing algorithm based on genetic algorithm is proposed to find the global optimal path by establishing the fitness function considering the absorption energy, residual ener-gy, energy consumption and waste energy of the nodes. What is more, fitness function proposed in this pa-per is compared with three other fitness functions,including fitness function considering minimizing energy consumption,fitness function considering the energy absorption, residual energy and energy consumption of the nodes on the path,and fitness function considering the energy consumption of the nodes on the path and the energy waste of the nodes in wireless sensor networks. Genetic algorithm is used to solve the four kinds of routing and the simulation analysis shows that the proposed routing algorithm is of the highest energy effi-ciency.关键词
