Abstract

The invention provides a self-adaptive adjusting method, which comprises the following steps of: acquiring information data, extracting at least one control variable reflecting an information auto-correlation according to the information data; sorting at least one control variable reflecting the information auto-correlation according to index demand; adjusting value of a controllable parameter corresponding to at least one control variable reflecting the information auto-correlation in a protocol stack according to the sorting result. The present invention also provides a sensor node and a sensor network having the sensor node. Moreover, the extracted control variable and the variable reflecting network communication condition received in the protocol stack can be combined and optimized according to the index command to realize the bilateral control, thus increasing the performance of network system.

Description

technical field

[0001] The invention relates to communication technology, in particular to an adaptive adjustment method, a sensor node and a sensor network. Background technique

[0002] Wireless Sensor Network (WSN for short) is a wireless network formed by a large number of low-complexity sensor nodes through self-organization. Each network node is composed of a sensing module, a processing module, a communication module and a power module. Complete three basic functions of data collection, data sending and receiving, and data forwarding. Wireless sensor networks have the characteristics of high reliability, easy deployment and scalability. The emergence of a new generation of smaller and cheaper low-power devices, the improvement of data computing and processing capabilities brought about by distributed computing, and the development of micro-electromechanical systems have enabled the development of low-cost, low-power, small-volume, short-distance communication devices...
