摘　　要：为解决无线传感器网络中节点数据传输实时性与使用寿命之间的矛盾,并实现无线传感器网络的Internet远程信息获取,本文建立了适合于远程信息获取的传感器网络通信模型;在该模型基础上,借鉴蚂蚁算法在无线adhoc网络中的应用,考虑到无线传感器网络要求能量消耗小、易损坏和移动性的特点,对蚂蚁算法进行改进,提出蚁后算法,分别从本地信息获取和远程信息获取两个角度对信息获取的可行性进行分析,使得Internet的信息获取成为可能,并提出建立新的无线传感器休眠模式,以解决无线传感器数据传输实时性和使用时间的矛盾;最后,利用网络仿真器对该算法进行了仿真,并且与SPIN协议所得的结果相对比,根据仿真结果对比分析其在能源利用和远程信息获取的可行性.Recently advantages of wireless sensor networks have germinated many new applications in both military and civil domains. Many researchers are engaged in scheming new algorithms for wireless sensor networks where energy awareness is an essential consideration. We identify the trends that wireless sensor networks should be maneuverable by users from Internet and propose a new algorithm that can fulfill long-distance communication and operation through Internet, by which the user can avoid unnecessary damages from dangerous environment. We develop a new model which imitates the process of ants＇ searching for food. Additionally, we describe our algorithm in details and simulate this algorithm. Finally, we conclude with several open research issues of this new protocol.
