With the growth in the computation capacity of sensor nodes, they are increasingly equipped to handle more complex functions. Moreover, the need to realize the complete loop of se...
—We investigate location distinction, the ability of a receiver to determine when a transmitter has changed location, which has application for energy conservation in wireless se...
The dynamic point coverage problem in wireless sensor networks is to detect some moving target points in the area of the network using as little sensor nodes as possible. One way ...
— An important class of queries over sensor networks are network-wide aggregation queries. In this work we study a class of aggregation queries which we refer to as aggregate thr...
Abstract--We propose "mode switch", an adaptive loadsensitive solution that supports both an energy-efficient operation mode for transmitting normal sensor data and an Qo...
