摘　　要：为解决混合光无线传感网络节点因自身能量耗尽而过早消亡的问题。结合改进的蚁群算法,对一般混合光无线传感网络节能路由算法进行优化。首先给出节能路由算法的假定条件,设置算法具体应用场景,然后构建混合光无线传感器网络通信能耗模型,最后从引入路径度量,改进前向蚂蚁和返回蚂蚁的信息素更新规则着手,提高传统蚁群算法收敛速度,以减少能量消耗,实现混合光无线传感网络节能路由算法优化。结果表明:与三种算法进行对比,所研究算法应用下,混合光无线传感网络节点消亡时间更晚,网络能量剩余更多,由此说明所研究算法能延长混合光无线传感网络使用寿命。In order to solve the problem of premature death of hybrid optical wireless sensor network nodes due to their own energy depletion. Combined with the improved ant colony algorithm, the general hybrid optical wireless sensor network energy-saving routing algorithm is optimized. Firstly, the assumption conditions of energy-saving routing algorithm are given, and the specific application scenarios of the algorithm are set. Then, the communication energy consumption model of hybrid optical wireless sensor network is constructed. Finally, the convergence speed of traditional ant colony algorithm is improved by introducing path measurement and improving pheromone update rules of forward ant and return ant, so as to reduce energy consumption and realize energy-saving routing in hybrid optical wireless sensor network Algorithm optimization. The results show that: compared with the three algorithms, the node death time of hybrid optical wireless sensor network is later, and the network energy surplus is more, which shows that the proposed algorithm can prolong the service life of hybrid optical wireless sensor network.
