The range searching problem is fundamental in a wide spectrum of applications such as radio frequency identification (RFID) networks, location based services (LBS), and global po...
Conventional wide-area video surveillance systems use a network of fixed cameras positioned close to locations of interest. We describe an alternative and flexible approach to w...
Duty-cycling in wireless sensor networks (WSNs) has both beneficial effects on network lifetime and negative effects on application performance due to the inability of a sensor to ...
