Method for wireless gateway to perform coverage calling on wireless network nodes and a computer readable storage medium

Abstract

The invention discloses a method for a wireless gateway to perform coverage calling on wireless network nodes and a computer readable storage medium. The method comprises the following steps: after the wireless network node wakes up, carrying out wireless signal detection by using inherent communication parameters; if a wireless signal frame is detected, receiving the wireless signal frame, and performing corresponding operation according to the requirement of the data frame; otherwise, entering the next dormancy period; the working period of the wireless gateway is t, the t comprises lead code time t1, data frame time t2 and dormant period time t3, namely t = t1 + t2 + t3; m is the number of coverage calls, and the initial value of m is 0; the working mode of the wireless gateway is as follows:1, enabling the wireless gateway to continuously work for n times according to a t period; 2, enabling m is equal to m + 1, determining whether the product of the number m of covered calls and the delay time td is larger than or equal to t or not; 3, if so, ending the whole calling process; otherwise, delaying the time td, and returning to the step 1. After the method is adopted, the wireless gateway can actively call all wireless network nodes within the signal coverage range of the wireless gateway.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for a wireless gateway to cover and call a wireless network node and a computer-readable storage medium. Background technique [0002] With the development of wireless technology, wireless communication has been widely used. There are basically two networking methods for current low-power wireless devices: one is that the wireless gateway is always in the receiving state at a fixed frequency point, and the wireless network node periodically sends wireless signals at the same frequency point, actively Looking for a wireless gateway that can be networked; another way is for the wireless gateway to send wireless signals and seek nodes for networking. The sleep cycle of the wireless network node must be less than the gateway wireless signal preamble time before it can be awakened by the gateway reliable call. Both of these methods have disadvantages: the f...

Problems solved by technology

Both of these methods have disadvantages: the former method brings troubles to the success rate of networking and network communication due to the presence of concurrent signals from network nodes; The signal time limit is stricter (for example, the original requirement is 5 seconds, and now 1 second is advocated). Only when the sleep cycle of the wireless network node is shortened, the gateway can reliably wake up the call, which brings huge challenges to the low power consumption of the wireless network node. challenge
