Abstract—Sensor networks have been deployed for many barrier coverage applications such as intrusion detection and border surveillance. In these applications, it is critical to o...
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 the research field of Wireless Sensor Networks (WSN), how to reduce the energy consumption of WSN so that the lifetime of WSN can be prolonged is one of the hottest spots. In t...
—We consider information retrieval in a wireless sensor network deployed to monitor a spatially correlated random field. We address sensor scheduling in each data collection und...
