Problems solved by technology

Therefore, most of the current wireless sensor networks use the existing network infrastructure (such as Internet, GPRS, etc.) to complete data transmission. This method has high data transmission costs and limited coverage, which cannot meet the current development needs of wireless sensor networks.

Abstract

The invention discloses a method for multithreaded communication between network nodes of a wireless sensor and a gateway and a wireless gateway device. The wireless gateway device employs logistic chaotic mapping to generate a key, chaotically disturbs information sent from the sensor to the gateway and information sent from the gateway to a sensor network by nonequivalence operation, can realize package forwarding and relaying functions of an embedded wireless local area network composed of a plurality of sensor nodes having sentience, computation capacity and real-time communication capacity, and finishes remote linear transmission of an area network.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a multi-thread communication method between wireless sensor network nodes and gateways. Background technique [0002] In practical applications, wireless sensor networks often have to communicate with other information devices. communication connection. For example, a user walks with a handheld PDA in an area covered by the network, and can access the temperature information on the temperature sensor in the remote wireless sensor network by accessing the Internet. The data monitored in w SN (Wireless Sensor Network) sometimes needs to be sent to the upper server for analysis and processing through the Internet. At the same time, the upper server sometimes needs to send related commands to the nodes in W SN to realize related tasks. Some application systems Among them, different types of wSN nodes also need to coordinate communication with each other to realize ...
