The constrained capacity of wireless sensor nodes and harsh, unattended deploy environments make the data collected by sensor nodes usually unreliable. We have proposed a count-min sketch based anomaly detection scheme with the goal of detecting the anomaly data values in WSN. In this paper, we analyze the performance of the proposed scheme thoroughly. We show through experiments with real sensed...
In this paper, we consider the performance of serial distributed detection in wireless sensor networks (WSNs) under the assumption that the local decisions made by sensors are transmitted over noisy channels. Different from the parallel fusion, where the local results are directly sent to the fusion center, in serial fusion, local results are transmitted to the fusion center through multi-hop, short-range...
Wireless sensor networks can enable the reliable information gathering and transmission for a variety of applications that range from environment protection and civil structure monitoring to battlefield surveillance. This paper presents an innovate detecting system based on wireless sensor networks for detecting occupancy of vehicle berth in car park The battery-powered wireless sensor nodes can be...
