摘要
针对传统基于逻辑拓扑的低压电力载波网络不可靠不稳定的问题,提出了一种基于虚拟IP的组网路由算法。该算法按深度优先遍历策略搜索全网,结合可变功率方法探测未知节点,根据节点间的信号衰减得出基于物理拓扑的网络平等簇结构,采用反映拓扑结构的虚拟IP进行网络编址,从而实现节点定位及高效路由。
In order to solve the problem of unreliability and instability in low voltage Power Line Carrier Sensor Network(PLCSN) conventionally based on logical topology,a virtual IP based networking and routing algorithm is proposed.The algorithm follows the depth-first traversal strategy to search the whole network,combining the variable power method to detect unknown nodes,and according to signal attenuation between nodes to calculate the physical topology based network equal cluster structure.Network addressing is achieved by virtual IP that reflects topology structure so that both node positioning and efficient routing are realized.
