Abstract

The invention provides a micro-power wireless communication method. The method comprises the steps that each wireless sensor node sends a Hello package including the routing information of the wireless sensor node and friendly node routing information to a neighbor node; each wireless sensor node receives the Hello package sent by the neighbor node; each wireless sensor node updates the friendly node routing information of the wireless sensor node according to the received Hello package sent by the neighbor node; the data sending priority of a friendly node is judged according to the information of the Hello package, and when the friendly node routing information includes the destination address of data needing to be sent, the data are sent or forwarded by utilizing a depth-first algorithm according to the data sending priority; the data sent by the neighbor node are received and processed. The data are sent or forwarded by utilizing the depth-first algorithm, the flooding phenomenon caused by network resource occupancy cannot happen, the hop count of the nodes in the network is increased, the network communication distance is increased, and the network coverage area is correspondingly increased.

Description

Technical field [0001] The present invention relates to wireless communication network technology, in particular to a micro-power wireless communication method. Background technique [0002] Various micro-power short-distance radio transmission devices have penetrated into people's lives, such as the well-known cordless phones, Bluetooth, wireless local area network, car distance radar, radio frequency identification, and ultra-wideband, which belong to the category of micro-power radio technology. The existing micro-power wireless communication devices are widely used in wireless meter reading, industrial telemetry, remote control, in automatic data collection, building automation, computer room equipment monitoring, security, access control systems, wireless keyboards, wireless mice, underwater positioning, alarms, etc. Industrial and civil equipment. [0003] In the existing wireless ad hoc network, the breadth-first algorithm is generally used for communication. The breadth-fi...
