| 摘 要： | 在无线传感器网络中,节点能量有限决定了路由协议需要高效利用能量.基于定向扩散协议在能量方面的不足提出一种改进协议DD-OH.采用自由空间模型,通过最佳跳数值控制探测数据的扩散范围,增强能量的高效利用.理论分析和仿真结果表明,与传统的定向扩散协议相比,改进的协议有效地减少了网络中节点的平均耗能,有利于延长节点和网络的工作寿命.

| Abstract: | Energy for nodes is limited in wireless sensor network, so it is necessary to make use of energy effectively by routing protocol. Based on directed diffusion, the paper presents an improved routing protocol which is named as DD_OH. By controlling the diffusion of exploratory message with optimal hops in free space model, the energy consumption can be more efficient. Theoretical analysis and simulation results show that DD_OH achieves average energy saving. |
