摘要: DD协议是一个经典的无线传感器路由协议。针对该协议能效方面的不足,提出一种能量高效的协议——自适应数据转发扩散协议(ADTDD)。通过自适应地控制节点的转发概率实现能量的高效利用。理论和仿真结果表明,与传统的DD协议相比,ADTDD协议降低了网络节点的能量消耗,延长了网络的生存时间。

Abstract: DD protocol is a classical wireless sensor network routing protocol.An improved routing protocol based on directed diffusion is presented-ADTDD(Adaptive Data Transmit Directed Diffusion protocol).By adaptive controlling the node’s percent of transmit to achieve efficient use of energy.Theoretical analysis and simulation results indicate that ADTDD achieves energy saving compared to prior method and the lifetime of wireless sensor networks is prolonged.
