Abstract

The invention discloses a hash algorithm-based terminal gateway load distribution method in an intelligent housing system. The load distribution in the invention is in a network composed of a plurality of terminal gateways and a local server; the terminal gateway uses a Zigbee coordinator to receive sensor data sent by a Zigbee sub-device and the data is stored in the server; a master control gateway segments the data into a plurality cells and maps the data to a hash ring; the location of the terminal gateway on the hash ring is replaced with a virtual node; the hashrate of the terminal gateway is shown by using the number of the virtual nodes; that is, when the terminal gateway joins an edge computing network, the master control gateway distributes the virtual nodes in a corresponding number for the terminal gateway according to the hashrate of the terminal gateway and the virtual nodes are mapped to the hash ring by using a hash function; the virtual node captures the closest data in a fixed direction so that the gateway system which has entered the edge computing state has the ability of distributing the load according to a hashrate specific value while joining and quitting theedge computing network dynamically.

Description

technical field [0001] The invention discloses a terminal gateway load distribution method based on a hash algorithm in a smart home system. Background technique [0002] Smart Home is that thing connectionization embodies under the influence of Internet of Things. Smart home connects various devices in the home (such as audio and video equipment, lighting system, curtain control, air conditioning control, security system, digital cinema system, audio and video server, shadow cabinet system, network appliances, etc.) Home appliance control, lighting control, telephone remote control, indoor and outdoor remote control, anti-theft alarm, environmental monitoring, HVAC control, infrared forwarding and programmable timing control and other functions and means. Compared with ordinary homes, smart homes not only have traditional residential functions, but also include construction, network communications, information appliances, and equipment automation, providing a full range of...
