Networking method and system for wireless sensor network based on multiple sink nodes

Abstract

The invention relates to a networking method for a wireless sensor network based on multiple sink nodes. The method is characterized by comprising the following steps of: 101, sending a control command for acquiring sensor data to the network by a control server according to demand; 102, acquiring the sensor data and sending to the sink nodes by ordinary nodes; 103, collecting the acquired sensor data, sending commands for acquiring the sensor data to the ordinary nodes and simultaneously sending the acquired sensor data to a wireless base station by the sink nodes; 104, performing time synchronization of each of the sink nodes by a time server; 105, sending the sensor data received by the wireless base station to a data server through the network, simultaneously sending the commands for acquiring the sensor data to the sink nodes, and configuring a long-distance wireless communication module for the wireless base station; and 106, storing the acquired sensor data by the data server.

Description

technical field [0001] The present invention relates to the technical field of wireless sensor networks, in particular to a method and system for networking a wireless sensor network with multiple convergence nodes. Background technique [0002] Wireless sensor network is a system that integrates wireless communication, sensor technology, embedded technology and distributed computing technology. The connection between the computing world and the ternary world of human society is also called the "Internet of Things". Sensor networks have important application value, such as intelligent transportation, environmental monitoring, precision agriculture, national defense and military, smart home, security monitoring, rescue and disaster relief and many other important fields have broad application prospects. At present, the promotion and application of this technology have been started in many industries, and certain results have been achieved. With the development of applicatio...

Problems solved by technology

However, when the network scale is large, the number of hops from the sensor node to the sink node will increase sharply, and the path will become very long. In addition to the instability of the wireless link itself and the hot spot problem of the sink node, the collected transmission The transmission of sensory data to the aggregation node will experience a large delay, the probability of successful transmission will also be reduced, and the energy consumption caused by a single sensory data transmission will also become very large. Therefore, the life of the network and the success of data collection The rate and delay will be seriously affected

[0004] At present, there are few networking methods based on multi-sink nodes, which can also be divided into two sub-categories: one category is a networking method that can only be applied to belt-shaped monitoring objects such as rivers, and this method has a wide range of applications. limitations
