Embodiment Construction

[0040] Fig. 1 is the flowchart of the first embodiment of the wireless sensor network local node management method of the present invention, specifically:

[0041] Step 1. At the current sampling time, the working nodes in the first node set predict the candidate area where the ideal node combination that can provide the best positioning performance at the next sampling time is located. The first node set is at the current sampling time. A collection of working nodes in working state;

[0042] Step 2. Each node in the first node set broadcasts prediction information including the candidate area to other nodes in the wireless sensor network;

[0043] Step 3. The node receiving the prediction information judges whether it is in the candidate area, if so, the node joins the second node set, and the second node set is the candidate to enter the working state at the next sampling time A collection of nodes;

[0044] Step 4. The candidate nodes in the second node set mutually conf...

Abstract

The invention relates to a local type node management method of the wireless sensor network, which comprises the steps that at the current sampling time, a working node in a first node collection can predict that the alternative area where the ideal node combination with the optimum positioning performance at the time of the next sampling is positioned can be provided; each node in the first node collection can broadcast the forecasting information including the alternative area to other nodes in the wireless sensor network; the node which receives the forecasting information judged whether is positioned within the alternative area, and if the node is positioned within the alternative area, the node is added to a second node collection; the alternative nodes in the second node collection can mutually confirm the location and the condition of the other node, and the alternative nodes can come into the working condition at the next sampling time. The invention can effectively avoid the disadvantages that the computing load of the traditional overall type node management method is large, the storage demand is large, the complexity of the system is large, the structure is complex, the expansibility is not strong etc., the invention can rapidly obtain the node combination which can position the object with very high precision, the working complexity of the system can be reduced, and the network service life can be prolonged.

Description

technical field [0001] The invention relates to a wireless sensor network node management method, in particular to a wireless sensor network local node management method. Background technique [0002] A wireless sensor network is composed of multiple miniature wireless sensors, each of which has the functions of wireless communication, data collection and processing, and collaborative cooperation. The sensor nodes in the wireless sensor network can be randomly or specifically arranged in the target environment. In the system, sensor nodes self-organize through a specific protocol, obtain information about the surrounding environment, and cooperate with each other to complete specific tasks. [0003] At present, wireless sensor network technology is widely used in medical and health, military applications, environmental protection, quality and safety, and animal and plant monitoring. Among them, passive target monitoring and tracking technology has received extensive attentio...
