Wireless sensor network for monitoring irrigation area and communication protocol of wireless sensor network

Abstract

The invention discloses a wireless sensor network for monitoring an irrigation area and a communication protocol of the wireless sensor network. A star topological structure is adopted in the wireless sensor network and comprises an information management center, a sink node and a plurality of sensor nodes deployed around the sink node and used for exchanging information with the sink node in a one-hop manner. Aiming at the characteristics of no limit to energy of the STAR-WSN (Wireless Sensor Network) sink node and more adoption of star structures, the communication protocol is used for improving a TDMA (Time Division Multiple Access)-based MAC (Media Access Control) protocol, and adopts an MAC protocol-STAR MAC oriented to single-coverage WSN monitoring application. According to the invention, automatic acquisition, transmission, display, storage and processing on site information of the irrigation area can be realized, and irrigation area management efficiency is increased, water utilization rate is increased, purposes of scientifically using water and saving water are achieved, and positive effects can be generated for developing agricultural economy and water conservancy economy of the irrigation area, effectively enlarging irrigation area, building a better ecological environment and realizing sustainable development of irrigation area economy.

Description

technical field [0001] The invention discloses a wireless sensor network for irrigation area monitoring and a communication protocol thereof, belonging to the fields of wireless sensor networks and electronic measurement and control. Background technique [0002] Most of the existing irrigation area information systems use wired methods to connect sensors such as water level, rainfall, sluice level, and soil moisture content with data collectors to transmit information such as water regime, rain regime, work condition, moisture condition, drought condition and weather. This method has the defects of complicated wiring, vulnerable to accidental damage, and high installation and maintenance costs. At the same time, when it is necessary to increase the measurement parameters, it is often necessary to modify the hardware and software of the data collector. The system has poor scalability and is inconvenient to use. In order to overcome the above shortcomings, it is a developmen...
