摘要
为了解决物联网专用频点自组网网络节点能量消耗容易失衡,当节点数增加时易产生链路故障的问题,设计一种改进物联网专用频点自组网驱动路由协议算法。以感知现场、汇聚节点和Internet为主要结构,构建物联网专用频点自组网网络模型。模型采用多媒体印刷读物(multimedia print reader,MPR)集合综合选取节点机制,以网络节点总能量消耗以及能量代价为基础,通过节点优化目标函数,确保自组网能量消耗处于均衡状态。通过网络路由协议改进算法,采用最小覆盖集实现物联网专用频点自组网链路故障的修复。结果表明,改进后的算法对路由链路信息转发具有良好的吞吐性能,可以提高网络数据传输性和连通性,并可增加节点生存时间,最终提升数据包到达率和数据控制量。
To solve the problem that the energy consumption of nodes in the ad hoc network at special frequency points of the Internet of things is easy to be unbalanced and link failure could occur when the number of nodes increases,an improved ad hoc network driven routing protocol algorithm of special frequency points of the Internet of things(IOT)was designed.The model of the ad hoc network at special frequency points of the IOT was constructed with the main modules of scene sensing,node converging,and the Internet.The model adopts multimedia print reader set to select nodes comprehensively.Based on the total energy consumption and energy cost of network nodes,the energy consumption of ad hoc network could be balanced by optimizing the objective function of nodes.With the improved algorithm of the network routing protocol,the least cover set could be used to repair the link failure of the ad hoc network at a special frequency point of the IOT.Results show that the algorithm had a good throughput performance for routing link information forwarding,improved the network data transmission and connectivity,increased node lifetime,and finally enhanced the packet arrival rate and data-control volume.
