Data capture is important for some critical network applications, such as network diagnosis and criminal investigation. In multi-channel wireless networks, the fundamental challenge for data capture is how to assign operation channels to wireless sniffers. The existing approaches make some impractical assumptions, such as the prior knowledge on network traffic and the perfect conditions of data capture...
Secondary user data capturing is a fundamental building block for cognitive radio network forensics. It faces great challenges mainly due to the unknown secondary user behavior, wide spectrum, and packet capturing uncertainty. There is a lack of fundamental understanding of the data capturing problem in theory. In this paper, for the first time, we formulate the dynamic sniffer channel assignment...
