Título: (EN) routing method and device as well as sensor equipment based on wireless sensor tree network
(ZH) 基于树形无线传感器网络的路由方法和装置及传感器设备
Resumen: front page image
(EN) The invention discloses a routing method and device as well as sensor equipment based on a wireless sensor tree network. The method comprises the steps of: allocating short addresses for sensor nodes in advance according to the layer and the intra-layer position, where each sensor node is in, in the tree network; inquiring the short address of a target sensor node according to a message to be transmitted; inquiring a pre-established neighbor table to acquire the short address of each neighbor node of the current sensor node; respectively calculating number of the basic routing hops from each neighbor node to the target sensor node according to the short address of each neighbor node and the target sensor node; and selecting a next-hop node from the neighbor nodes according to the basic routing hop number obtained through calculation, and forwarding the message to the next-hop node. The method disclosed by the invention benefits the increase of the routing transmission efficiency of the sensor nodes in a message forwarding process.
