Node Selection Approach for Data Compression in Wireless Multimedia Sensor Networks

Multimedia sensor network is an advanced form of sensor networks. It has multimedia informa-tion perception, processing and transmission capacity. For the problem of great redundancy and correla-tion in the collection data, a node selection approach for data compression was designed. By using the correlation model based on three-dimensional perception, it describes the relevant characteristics between the observed images data. Then the camera node selection algorithms was proposed based on correlation coefficients to reduce the spatial redundancy of sensing data. A set of comparisons are performed to evalu-ate the effective of our algorithms.
