The cable acquisition and control system of the traditional greenhouse has many disadvantages such as complicated wiring, high cost and lack of accuracy and expansibility. In order to solve those problems, a greenhouse acquisition and control system based on ZigBee wireless sensor network (WSN) is designed in this paper. The ZigBee with temperature sensor DS18B20 and humidity sensor AM2301 is used...
In this paper we address the problem of decentralized event detection in a large-scale wireless sensor network (WSN). Comparing with existing centralized solutions, decentralized algorithms are superior in energy efficiency and network scalability, and thus fit for the distributed nature of a WSN. We formulate the event detection problem as a linear program, and solve it with the alternating direction...
