| 摘 要： | 路由协议是无线传感器网络研究的关键技术之一，以数据为中心的路由协议是目前研究的热点。基于局域性更新机制的原理，改进了以数据为中心的Directed Diffusion协议，用C＋＋语言描述了协议的算法，在NS2仿真平台下根据不同参数设置场景，进行了仿真；与Directed Diffusion协议的性能做了比较，结果表明改进后的路由协议具有较少的时延和开销。

| Abstract: | The routing protocol is one of the key researching techniques for wireless sensor network, and the data-centric routing protocol is thehotspot of study at present. Based on locality updating mechanism, the data-centric Directed Diffusion protocol is improved. In different simulationscenes of different parameters, the improved protocol depicted by C++ is simulated on the NS2 platform. Compared with the performance ofDirected Diffusion protocol, the improved protocol has less delay and overhead. |
