Abstract— The paper describes a target tracking system running on a Heterogeneous Sensor Network (HSN) and presents results gathered from a realistic deployment. The system fuses...
—Wireless Sensor Networks (WSNs) consist of spatially-distributed autonomous sensors that can cooperatively monitor physical and environmental conditions. Because of sensors’ r...
Data gathering is a basic activity of many wireless sensor network applications. We propose a novel collaborative data gathering approach utilizing data co
—Wireless sensor networks are often composed of resource-constrained sensor nodes with limited memory space, computational capacity and communication range. The links in WSN are ...
Abstract. To process aggregation queries issued through different sensors as access points in sensor networks, existing algorithms handle queries independently and perform in-netw...
