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 the hotspot of study at present. Based on locality updating mechanism, the data-centric Directed Diffusion protocol is improved. In different simulation scenes of different parameters, the improved protocol depicted by C++ is simulated on the NS2 platform. Compared with the performance of Directed Diffusion protocol, the improved protocol has less delay and overhead.
