Abstract

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.

Description

technical field [0001] The present invention relates to the technical field of wireless sensor networks, and more specifically relates to a routing method and device and sensor equipment based on a tree-shaped wireless sensor network. Background technique [0002] Wireless sensor network combines sensor technology, communication technology and computer technology, and has the ability of information collection, transmission and processing. The sensor network originally originated in the military field, but with the development of sensor network technology, its application range is becoming wider and wider, and it has broad application prospects in the fields of environmental monitoring, smart agriculture and smart home. [0003] A sensor node in a wireless sensor network is a microsystem with information collection and processing capabilities. The sensor node can communicate with other nodes, but the communication distance of the node is limited, so when the source node need...
