Ad-HOC ad hoc network system and method

Abstract

The invention discloses an Ad-HOC ad hoc network system and an Ad-HOC ad hoc network method. The Ad-HOC ad hoc network system comprises a host and a plurality of node modules. Each node module is in wireless communication with the host, wherein the host is used for sending a configuration file to the node modules, and the node modules are used for reading and storing network group number information and frequency hopping parameter information in the configuration file after receiving the configuration file. And the node module is also used for setting the network group number and the wireless communication frequency of the node module according to the network group number information and the frequency hopping parameter information. According to the Ad-HOC ad hoc network system and method, the signal data accuracy and transmission timeliness of the multi-node module during long-distance transmission can be ensured.

Problems solved by technology

[0003] The inventor finds in the process of realizing the present invention, the hardware cost height of Zigbee wireless ad hoc network technology, communication stability is poor, lacks the shortcomings such as direct communication with the Internet to be the bottleneck of Zigbee technological development all the time

At present, the domestic Zigbee technology mainly adopts the 2.5G frequency in the ISM frequency band, which has weak diffraction ability and weak wall penetration ability.

In the home environment, even a door, a window, or a non-load-bearing wall will greatly reduce the signal

Some manufacturers will use RF power amplifiers to amplify 2.5G signals, but this will cause additional radiation pollution, and it also runs counter to the original intention of Zigbee's low power consumption and energy saving

Secondly, using the Zigbee protocol stack for application development requires a certain technical foundation, and the high difficulty of development is also the technical threshold for the large-scale implementation of Zigbee technology

Furthermore, the ad hoc network system of Zigbee technology needs to state the network group number and channel number in the program code, which is not conducive to the secondary multiplexing of hardware.
