To meet the special requirements on micro-climate raised by the greenhouse in Northeast China, we develop a WSN-based greenhouse environment monitoring system. We decrease the power consumption of nodes, reduce the complexity of system development and simplify the deployment of nodes by dormancy mechanism, single-hop transmission, and on-demand deployment. Gateway node transmits the sensor data to...
This paper targets the identification of faulty sensor nodes, which is one of the most important sources of faults in wireless sensor networks. To explore an effectual technique for node self detection, a new algorithm, Node Self Detection by History data and Neighbors (NDHN) is proposed in this paper. This algorithm collects the characteristics of the nodes to compute the biases through historical...
The accurate traffic model and prediction of mobile network plays an important role in network planning. It is particularly important for the performance analysis of mobile networks. The study in this paper concerns predicting the traffic of mobile network, which is essentially nonlinear, dynamic and affected by immeasurable parameters and variables. The accurate analytical model of the traffic of...
