In a wireless video sensor network (WVSN), each video sensor node consumes a significant amount of power on video compression in addition to the required power for communication. Therefore, the power optimization is a more critical issue in WVSN. This paper presents a cross-layer algorithm for the minimization of the total power in a video sensor network organized in a clustered architecture. The...
In a sensor network, each sensor has a limited energy supply. Therefore, it is critical to minimize the power consumed by each sensor to maximize its lifetime. Video sensor networks differ from conventional sensor networks in the fact that video compression at the sensor node consumes a significant amount of power comparable to that used for communication. This poses new challenges, and renders power...
