Problems solved by technology

[0006] The purpose of the present invention is to solve the problems that the current wireless sensor network nodes and gateways need special chips or high-performance processors, and the wireless signal detection and transmission time of the sensor nodes are long, the power consumption is large, and it is unfavorable to use batteries for power supply. Invent a new communication method between wireless sensor network nodes and gateways by using the characteristics of wireless sensor nodes themselves, so as to realize two-way wireless communication between lower performance wireless sensor network nodes and gateways, and extend sensor operating life of nodes, and reduce product cost

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] The communication method between the wireless sensor network node and the gateway of the present invention adopts the communication mode in which the sensor node is the "master" and the sensor gateway is the "slave", and the channel occupation adopts frequency division multiplexing FDMA and time division multiplexing Combined with TDMA.

[0037] (1) The sensor node actively sends out a signal at regular intervals to complete the registration of the sensor node on the gateway and upload the collected data.

[0038] (2) The sensor gateway only sends the necessary response signal after receiving the registration request and uploading data sent by the sensor node, and does not actively transmit any wireless signal outside at ordinary times.

[0039] (3) Each sensor gateway only occupies one wireless channel, and the sensor gateways installed adjacen...

Abstract

The disclosed new communication method between a wireless sensor node and gateway comprises: with the feature of every node, applying the master (node)-slaver (gateway) way; assigning one wireless channel for every sensor gateway to store all managed ID and corresponding SN; registering the sensor node to build connection with gateway and obtain running parameters; then, gathering and sending monitor data. This invention is simple fit to run on low-performance SCM, and can prolong sensor node lifetime.

Description

technical field [0001] The invention relates to a communication method, in particular to an energy-saving communication method applied between nodes and gateways in the field of wireless sensor networks, in particular to a communication method between nodes and gateways in wireless sensor networks.
