In this paper, we consider the problem of modeling and analyzing the application communication reliability of wireless sensor networks (WSN) with different topologies, including star, tree, mesh, and hierarchical clustering. We propose reliability measures that integrate the conventional connectivity-based network reliability with the sensing coverage measure of WSN. We apply a reduced ordered ...

Wireless Sensor Networks (WSN) generates a huge amount of data for efficient application of discovering essential knowledge from it is important. Usually, WSN data is generated in streams and forwarded to a sink. Raw data leads to higher communication overhead adversely affecting WSN performance. Association mining processes data to locate frequent patterns. Thus, when association mining is app...
