摘要
在无线传感网络中,簇的划分以及簇内节点访问顺序对网络生存周期具有重要影响。为了提高分簇网络生存周期,提出一种分簇融合的方法。采用ISODATA聚类法实现网络的分簇,在簇内由移动代理对数据进行融合。将移动代理路由归结为一个优化问题,采用蚁群算法求出移动代理迁移的最优路径序列。实验以能耗和网络延时作为评价指标,结果表明该算法可以有效的降低网络能耗,提高网络生存周期。
s In wireless sensor networks, clustering and access sequence of sensor nodes make a great impact on life cycle of clustering networks. In order to extend life cycle of clustering networks, a cluster and fusion strategy is proposed. The proposed method applies ISODATA clustering algorithm to partition wireless sensor networks and utilizes mobile agent fusing information inside clusters. Mobile agent routing can be treated as an optimization problem. Ant colony algorithm is used to find out the optimal nodes＇ sequence of mobile agent routing. The experiment adopts energy time as the performance metric. The simulation results show that the algorithm has smaller energy consumption of the network and extends the life cycle of network.
