摘要
为了降低节点能量消耗,延长网络生存的时间,提出了一种改进蚁群算法的无线传感器网络路由机制。首先将无线传感器网络服务质量分为3类,然后利用蚁群算法可以自适应网络状况动态性的优势,构建传感器节点转移函数和信息素更新规则,自适应构建数据路由,最后采用仿真模拟实验对算法性能进行检验。实验结果表明,相对于与现有无线传感器路由算法,本文通过引入蚁群优化机理挖掘传感器节点之间的关联性,数据传输延迟、可靠性和能量开销上具有更好的性能,使整个网络性能保持最优。
In order to reduce the energy consumption of the nodes and prolong the lifetime of the network,a new routing mechanism of wireless sensor network based on improved ant colony algorithm is proposed in this paper. Firstly,the quality of service is divided into 3 categories for wireless sensor network,and then ant colony optimization algorithm is used to dynamic adaptive network situation to construct sensor node transfer function and the pheromone updating rule and improve the adaptability and energy balance data routing construction,finally the simulation experiments are carried out to test the performance of the algorithm. The experimental results show that,compared with the existing routing algorithm of wireless sensor networks,this proposed algorithm can mine association of sensor nodes and obtain better performance of data transmission delay,reliability and energy cost with,so that the whole network can maintain optimal performance.
