Research on routing energy saving technology of wireless sensor networks based on distributed software definition based on cellular automata

针对软件定义的无线传感器网络的节能问题,文章提出一种将元胞自动机用于分布式SD-WSN路由设计的节能机制。该机制在分布式控制器中设置CA处理模块,节点自组织形成以分布式控制器为中心的二维元胞自动机区域。控制器采用节点的智能邻居列表计算节点的CA状态,节点根据控制器发布的CA指令匹配自身流表,切换工作状态进行休眠/唤醒以实现节能。仿真实验结果验证了该机制能降低网络能耗,延长网络生存周期。

To solve the energy-saving problem of software-defined wireless sensor networks, an energy-saving mechanism using cellular automata for distributed SD-WSN routing design is proposed in this paper. The CA processing module is set up in the distributed controller, and the nodes self-organize to form a two-dimensional cellular automata region centered on the distributed controller. The controller calculates the CA state of the node by using the intelligent neighbor list of the node. The node matches its own flow table according to the CA instruction issued by the controller, and switches the working state to sleep/wake up in order to save energy. The simulation results show that the mechanism can reduce the network energy consumption and prolong the network lifetime.
