摘　　要：定向扩散协议作为一种经典的以数据为中心的无线传感网络的路由协议,得到了广泛的认可。但是在复杂质询的应用中,定向扩散协议采用的泛洪质询算法的能效性非常低,本文在此基础上提出了一种改进算法,可以将复杂质询分成若干个子质询,节点在收到质询消息后,可以先通过向d跳之内的相邻节点收集信息来解决质询消息。并将改进算法与传统的泛洪质询算法进行了比较,比较结果显示,改进算法在网络的能效性方面有了不错的提高。As an attractive Data-centric protocol in Wireless Sensor Network,Directed Diffusion has been widely accepted.Directed Diffusion uses the flooding algorithm,but its energy efficient is very low with the application of the complex inquiries.In the modified algorithm,the complex inquiries can be divided,and when a node receives a inquiry message,it will collect the messages from the adjacent nodes to solve the problem firstly.The result of the comparison shows that the modified algorithm saves energy of the whole network.
