| 摘 要： | 不同于传统的网络,无线传感器网络能够协同地进行实时监测、感知和采集网络覆盖区域中监测对象的信息,并对其进行处理,处理后的信息通过无线方式传送,并以自组多跳的方式传送给观察者。路由协议的研究是无线传感器网络研究重点之一。蚁群算法是一种模仿自然界蚂蚁觅食的仿生算法,生物学家经过长期观察发现,蚂蚁总能够在巢穴和食物源之间找到一条最短路径。文中采用蚁群优化策略,给出了一种SMR多路径路由协议的改进算法ACO-SMR。该算法在保留SMR算法优点的基础上,进一步提高了资源利用率和路径稳定性,以及延长了网络生存时间。

| Abstract: | Wireless sensor network which is different from traditional network can monitor, apperceive and gather the information from the network coverage area. After being disposed,the information will be transformed to the observers by self-organizing and multi-hop way. The research of the routing protocol is one of the important researches in WSN. Ant colony algorithm imitates ants to look for food. By observing for a long time,biologists find ants always can find a shortest way between the source and the nest. By using the biological sim- ulation strategy ,propose an improved SMR routing protocol algorithm called ACO-SMR based on ant colony algorithm. This algorithm can utilize the advantages of SMR and can further improve the effective use of resources, the selection of stable paths and lifetime of net- work. |
