摘要
现有无线传感器网络的路由协议大多基于通用的Mesh路由考虑,在能效信息网络中,数据采集测量节点、能效信息业务量以及节点的位置相对固定,从而导致传统的无线传感器网络路由方法在能效信息网络中运行效率不高.针对能效信息网络的上述特点提出一种基于能效信息业务的新型路由方法(SPIN-DD),在SPIN路由协议的基础上融入定向扩散路由机制的基本思想,在能效终端与能效数据集中器之间建立了高效的通信连接.通过四节点仿真拓扑说明SPIN-DD的路由协议更新与配置过程,并进行SPIN-DD最佳路由长度的优化分析.在OMnet平台中搭建了能效信息采集网络仿真平台,对所提出的方法进行了验证.仿真结果表明,与已有方法相比,SPIN-DD在路由传播与路由更新时减少了不必要的邻居关系维护,具有更短的数据传输延迟以及更少的网络开销.
Existing routing protocols are focused on the common network. In the energy efficiency information network, the data acquisition measurement node and the volume and the node position of energy efficiency information are almost fixed, which lead to low efficiency of traditional wireless sensor network routing applications in energy efficiency information network. According to the above characteristics of the energy efficiency information network, a novel routing method based on energy efficiency service was proposed by integrating SPIN routing protocol and the basic idea of directed diffusion routing mechanism. High efficient communication channel was established between energy efficiency terminals and concentrator. The updating and configuration process and optimization analysis of the best route length of SPIN-DD was described by the 4-nodesimulation topology. Finally, the simulation platform of energy efficiency information collection network was constructed in OMnet to verify the proposed method, and simulation results show that, compared with the existing methods, SPIN-DD reduces unnecessary neighbor relationship maintenance in routing propagation and routing updates and has shorter transmission delay as well as less network overhead.
