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...
We explore camera scheduling and energy allocation strategies for lifetime optimization in image sensor networks. For the application scenarios that we consider, visual coverage ov...
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...
