Abstract— The 802.15.4 WSN standard provides optional reliability through positive acknowledgments. Since positive-ACKs are not designed for energy efficiency, there is significa...
Wireless networks of visual sensors have recently emerged as a new type of sensor-based intelligent system, with performance and complexity challenges that go beyond that of exist...
Network lifetime maximization is a critical issue in wireless sensor networks since each sensor has a limited energy supply. Different from conventional sensors, video sensors com...
— In this paper, we study the angle coverage problem in visual sensor networks where all sensors are equipped with cameras. An object of interest moves around the network and the...
