Abstract

The invention relates to a seamless connection multi-gateway WSN structure and belongs to the technical field of the Internet of Things. Framework construction of the WSN is performed by using multiple gateways and frequency reuse, and therefore the system capacity is greatly improved; and shared nodes are adopted at edges of subnets to enable the shared nodes to be connected with adjacent subnets simultaneously. According to the structure, seamless connection among the subnets is achieved and the transmission delay is effectively reduced.

Description

technical field [0001] The invention relates to a seamlessly connected multi-gateway wireless sensor network structure, which belongs to the technical field of the Internet of Things. Background technique [0002] Sensor nodes can continuously perform data collection, event detection, event identification, location monitoring, and node control. These characteristics and wireless connection methods of sensor nodes make the application prospects of wireless sensor networks very broad, and can be widely used in military, environmental monitoring and Forecasting, health care, smart home, building status monitoring, complex machinery monitoring, urban transportation, space exploration, large workshop and warehouse management, and safety monitoring of airports and large industrial parks, etc. With the in-depth research and wide application of wireless sensor networks, wireless sensor networks will gradually penetrate into various fields of human life. However, in different applic...
