本发明公开了一种无线传感器网络的分簇路由方法,该方法包括:从无线传感器网络中随机选取若干节点作为簇首节点,各个簇首之间的通信采用低功耗有损网络路由协议RPL方式;当簇首节点向外发送OFFER消息邀请其他节点成为其簇成员节点时,根据当前簇首节点在RPL路由树中的位置控制该簇首节点所携带的簇成员节点数量,完成分簇组网过程;在进行数据路由时,簇成员节点将采集到的数据通过单跳路由的方式发送至对应的簇首节点;簇首节点采用RPL路由方式将数据传递至根节点。通过采用本发明公开的方法,降低了拓扑树的深度、均衡了各节点的能耗、保持了网络的连通性、提高了网络稳定性的。
A method for clustering routing in a wireless sensor network includes: randomly selecting a plurality of nodes from a wireless sensor network as a cluster head node, and communicating among the cluster heads using a low-power lossy network routing protocol RPL When the head node sends an OFFER message to invite other nodes to become its cluster member nodes, the number of cluster member nodes carried by the head node of the cluster is controlled according to the position of the first cluster head node in the RPL routing tree to complete the cluster group Network process; During data routing, cluster member nodes will be collected by a single hop routing data sent to the corresponding cluster head node; cluster head node using RPL routing data to the root node. By adopting the method disclosed by the invention, the depth of the topology tree is reduced, the energy consumption of each node is balanced, the connectivity of the network is maintained, and the stability of the network is improved.
