We study the problem of tracking an object that is moving randomly through a dense network of wireless sensors. We assume that each sensor has a limited range for detecting the pr...
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...
Effective and efficient power management remains one of the most formidable obstacles that must be overcome before Wireless Sensor Networks can be deployed on a widespread basis. E...
As sensors in a network are mostly homogeneous in software and hardware, a captured sensor can easily expose its code and data to attackers and further threaten the whole network....
Emerging sensor network technologies are expected to substantially augment applications such as environmental monitoring, health-care, and home/commercial automation. However, muc...
