基于邻节点覆盖的电力线通信组网路由算法

Routing algorithm of power line communication network based on covering-neighbor nodes

为扩大低压电力线载波网络的通信范围并提高网络通信可靠性,提出一种基于邻居节点覆盖的分簇路由组网算法。提出覆盖优先策略与转发优先权机制,为相邻簇节点分配不同的转发优先权,实现簇头的初步筛选,结合簇节点的优先转发权引入动态延时转发机制,进一步确定簇节点的角色。仿真结果表明,与非交叠分簇算法相比,该算法能有效降低节点间的传输延时并建立多条通信路径,提升系统的可靠性。

To enlarge the communication range and improve the reliability of the low-voltage power line communication network,a clustering routing algorithm based on covering-neighbor nodes was proposed.Cover priority strategy and forward priority mechanism were put forward for the adjacent cluster nodes to be assigned with different priorities so as to achieve preliminary screening of cluster heads.The priority forward right of cluster nodes was combined into dynamic delay forwarding mechanism to further determine the role of the cluster nodes.Simulation results show that compared with the non-overlapping clustering algorithm,the proposed algorithm can effectively reduce transmission delay,establish multiple communication paths,and improve the reliability of the system.
