Networking method of master-slave low-power-consumption wireless ad hoc network

Abstract

The invention discloses a networking method of a master-slave type low-power-consumption wireless ad hoc network. The networking method of the master-slave type low-power-consumption wireless ad hoc network comprises the following steps that a gateway node is powered on and initialized, and sensor nodes are powered on and initialized; the gateway node actively sends a broadcast awakening command to the sensor nodes to awaken the sensor nodes; the gateway node issues a roll call instruction, and each sensor node sends its own address to the gateway node; the gateway node issues a networking instruction, and the sensor nodes send information of the sensor nodes and information of the sensor nodes close to the sensor nodes to the gateway node; the gateway node actively registers information of each sensor node; and after the gateway node registers the addresses of the sensor nodes, the gateway node sends a networking ending command, and the sensor nodes enter a low-power-consumption mode.The method has the advantages of being high in networking speed and low in sensor node power consumption.

Description

technical field [0001] The invention belongs to the technical field of wireless ad hoc networks, and in particular relates to an ad hoc method for a master-slave low power consumption ad hoc network. Background technique [0002] The wireless ad hoc network is a temporary, multi-hop autonomous system composed of a group of mobile nodes with wireless transceiver devices. Center, strong invulnerability and other characteristics. The wireless ad hoc network node antenna can quickly receive the wireless signal of the adjacent node, and the router node of the node starts the routing algorithm according to the position of the adjacent node at that time, automatically adjusts the communication relationship between the nodes, and forms a new network topology. [0003] Wireless sensor networks are mainly used to periodically read real-time data from all sensor nodes in the network, such as temperature, humidity, flow, pressure, flow velocity, air indicators and other data collection...

AI Technical Summary

Problems solved by technology

In the wireless sensor ad hoc network, the sensor products of each node are often not powered by mains power, but are powered by batteries. Due to the long communication time and large data packets of the traditional ad hoc network technology, the power consumption of the sensor nodes is large. Battery power cannot meet the demand, which limits the popularization and application of sensor ad hoc networks

[0004] At present, the sensor node only stores its own information and does not have the information of nearby nodes. In addition, in the current wireless network, it is necessary to manually register the address (number) of the installed sensor node in advance; the manually registered sensor node address must be entered in advance into the base network management node or By remote downloading to the network management node, when a node needs to be replaced, the network needs to be re-registered, which is very inconvenient
