【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DirectedDiffusion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DirectedDiffusion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。更多还原

【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.更多还原
