为了在已有RPL组播路由协议的基础上,改进无线传感网关键转发节点轮换机制,在DAO消息option选项中增加能量剩余参数和转发节点更换阈值后,根据网络规模和组播接收节点数,转发节点轮换阈值,使能量充足的转发节点参与到分组转发中.当节点能量减少到设定的阈值后,切换转发节点,保证各节点的能耗均衡,从而设计出最优转发节点集.通过仿真可知;该算法可以有效控制节点能耗,提高网络节点的平均使用时间,延长网络生存周期.
Research on NB-IoT Clustered RPL Multicast Routing Algorithm Based on Wireless Sensor Network
In order to improve the rotation mechanism of key forwarding nodes in wireless sensor networks based on the existing RPL multicast routing protocol,the energy remaining parameter and forwarding node re-placement threshold are added to the DAO message option.Based on the network size and the number of multi-cast receiving nodes,the forwarding node rotation threshold is set to allow energy-efficient forwarding nodes to participate in packet forwarding.When the node energy decreases to the set threshold,the forwarding node is switched to ensure that the energy consumption of each node is balanced,and the optimal forwarding node set is designed,It can be concluded through simulation that this algorithm can effectively control node energy con-sumption,improve the average usage time of network nodes,and extend the network lifetime.
