摘要：Event query processing is a very important issue in wireless sensor networks (WSNs). In order to detect event early and provide monitoring information and event query timely in WSNs, an efficient intelligent collaborative event query (ICEQ) algorithm is proposed, in which sensor nodes that are near to the boundary of events are selected to accomplish complex event monitoring and query processing through intelligent collaboration. ICEQ will select range-nearest neighbors as the basic components of surrounding nodes. Then it will identify the gaps between the surrounding nodes and try to select the nearest neighbor collaborative nodes for enclosing the event in the node selection phase, which can avoid redundant sensor nodes to join surrounding nodes via identifying a set of association surrounding nodes between the nearest sensor nodes and the query events. Detailed experimental results and comparisons with existed algorithm show that the proposed ICEQ algorithm can achieve better performance in terms of query-processing time, average number of selected collaborative nodes, and query message consumption.
