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.
Aiming at the problems of low data transmission efficiency, high energy consumption and high end-to-end delay in routing decision making mechanism of three-dimensional heterogeneous network, based on the establishment of three-dimensional IOT model and communication model, Based routing decision mechanism based on Cellular Automata and nodes average received signal strength based on the establishment of network node data forwarding guidelines; through IPv6 addressing to complete the routing optimization and control; data forwarding mechanism and addressing strategy Based on this, a decision mechanism of IOT routing based on cell addresses is established. The simulation results show that the routing mechanism has a packet delivery rate of 82% -95% and a routing overhead ratio of 20% -35%. The average end-to-end delay is about 20 ms, while ensuring the IOT communication indicators, while improving the reliability and stability of the network operation.
