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...
Clustering has been well known as an effective way to reduce energy dissipation and prolong network lifetime in wireless sensor networks. Recently, game theory has been used to model clustering problem. Each node is modeled as a player which can selfishly choose its own strategies to be a cluster head (CH) or not. And by playing a localized clustering game, it gets an equilibrium probability to be...
In this paper, we focus on solving the decentralized consensus optimization problem defined over a networked multi-agent system. All the agents shall cooperatively find a common minimizer of the overall objective while each agent holds its own local objective and can only communicate with its neighbors. Motivated by many applications in which the local objective is the sum of a differentiable part...
A system which was proposed used temperature sensor, pressure sensor, infrared sensor and wireless communication network to monitor the productive process of boiler. Each wireless sensor module was spreaded each relevant position which needed to monitor in the productive process of boiler. The monitored data was sent to the master control box to analyse. The productive process was monitored by the...
Aiming at the shortcomings of the low energy adaptive clustering hierarchy (LEACH) routing protocol, an improved protocol in scenario with uneven clustering is proposed. In order to choose the right cluster-head, it considers many factors, including the residual energy of sensor nodes, the distance between the nodes and the base station, the difference of each node and the time of the node as a cluster-head...
In this work, we focus on the problem of fault tolerant data collection in heterogeneous Intelligent Monitoring Networks(IMNs). IMNs are expected to have a wide range of applications in many fields such as forest monitoring, structural monitoring, and industrial plant monitoring. We present our fault tolerant data collection scheme in the hierarchical structure of IMNs. We use an interesting technique...
This paper addresses the problem of joint multi-source localization and environment perception in wireless sensor networks (WSNs) based on received signal strength (RSS). Contrary to the traditional RSS approaches which assume known number of sources and known parameter of environments, we propose to estimate the sources with unknown number and the unknown environmental parameter simultaneously. By...
Measurements of wireless sensor networks (WSNs) are often polluted by random measurement noises and corrupted by unpredictable sensory reading errors. For a typical field monitoring scenario, this paper considers to correct sensory reading errors and recover the monitoring field, subject to measurement noises. The key factor to enable successful de-noising and error correction is that the monitoring...
In order to prevent the malicious attack from reducing the accuracy of aggregation result in wireless sensor networks, it is necessary to perform the attack detection in the received readings of all the sensor nodes before the resilient aggregation processing. However, the detection probability of the attack detection algorithm presented in the literature is small, and its computation complexity is...
