摘 要: 针对三维异构物联网路由决策机制存在的数据传输效率低、能量消耗大以及端到端时延高等问题,在建立三维物联网模型与通信模型的基础上,提出了基于元胞地址的三维异构物联网路由决策机制.在元胞自动机和节点平均接收信号强度的基础上建立网络节点数据转发准则;通过IPv6寻址来完成对路由的优化和控制;在数据转发机制和寻址策略的基础上,建立基于元胞地址的物联网路由决策机制.仿真结果表明,该路由机制的分组投递率为82%~95%、路由开销比为20%~35%,平均端到端延迟最大约为20 ms,在保证物联网通信指标的同时,提升了网络运行的可靠性和稳定性. A three-dimensional heterogeneous routing decision-making mechanism may have some prob- lems, including low data transmission efficiency, high energy consumption and poor end-to-end delay in lnternet of things (loTs). One routing decision-making mechanism based on cellular address (RDCA) was proposed with the establishment of a three-dimensional communication model. The RDCA established network node data forwarding guidelines based on cellular automata and node average received signal strength. The RDCA completed the route optimization and control by IPv6 addressing. The- routing deci- sion- making mechanism was resolved by the cellular address. The simulation results showed that the packet delivery fraction of RDCA was between 82% and 95%, routing consumption ratio was between 20% and 35%, and average end-to-end delay was 20 ms. It can not only ensure IoTs communication per- formance index, but also improve network reliability and stability.
