Hybrid listening and sleeping method for wireless sensor and wireless sensor

Abstract

The invention provides a hybrid listening and sleeping method for a wireless sensor and the wireless sensor. The method comprises the following steps: in N (N=N1+N2) monitoring and sleeping cycles, monitoring wake-up packets sent by a collector or a mobile terminal by the wireless sensor in N1 monitoring and sleeping cycles by using a first monitoring time length, and monitoring wake-up packets sent by the mobile terminal in other N2 monitoring and sleeping cycles by using a second monitoring time length, wherein the first monitoring time length is greater than the second monitoring time length, N1 is less than or equal to N2, and N1 first monitoring time lengths and N2 second monitoring time lengths are distributed at intervals. Compared with the way of using a single monitoring time length in the prior art, the hybrid listening and sleeping method for the wireless sensor provided by the invention reduces the monitoring total time length in the N monitoring and sleeping cycles, thereby reducing the monitoring power consumption of the wireless sensor.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a hybrid monitoring and dormancy method of a wireless sensor and a wireless sensor. Background technique [0002] With the evolution and development of wireless sensor networks, its application fields are becoming more and more extensive. The most commonly used scenario for wireless sensor networks is the data monitoring and acquisition system. The data monitoring and acquisition system collects data through wireless sensors and sends the collected data to data processing. The server does the aggregation, processing, etc. Data monitoring and acquisition systems usually support two modes: remote data acquisition and short-distance data acquisition. Remote data collection refers to the communication between the wireless sensor responsible for the corresponding data collection and the remote collector, and the collected data is sent to the collector, and then ...

Problems solved by technology

[0004] However, in the existing time-asynchronous monitoring sleep method, the wireless sensor uses the same monitoring time for the collector and the mobile terminal, which increases the power consumption of the wireless sensor within the monitoring time, resulting in a large power consumption of the wireless sensor.
