Cloud and Network Security Laboratory, CANS Lab, is formerly known as High-speed Network Laboratory, HSNET Lab. The Lab focuses on the cloud network management and security-related research and practice. The main research covers network security, network communications, network traffic management, cloud computing, digital forensics, IoT, botnet, VANETs and other fields as well. The Lab published numerical papers on IEEE Transactions and other well-known journals and completed implementation of prototypes of several cloud security systems, and achieved several invention patents. Most graduate members serve in telecommunication companies, netcom manufacturers or related institutions and universities. Basically, M.S. student before graduation in the Lab should publish a conference paper at least.


Wireless communication and network laboratory (WCN) was founded by Dr. Chih-Wen (Wenson) Chang in Department of Electrical Engineering, National Cheng Kung University in August 2006. The current research interests of the WCN Lab include radio resource management (RRM) and cross-layer optimization for the wireless communication systems. Recently, we have investigated several critical RRM issues for the 3.5G, 4G and more advanced wireless communication systems, e.g. WCDMA, HSPA, MC-CDMA, OFDM-based and CR systems. Now, we are interested in the following and related issues: 1. Radio resource management for the 4G, 5G, femto-cell systems and CR network. 2. Performance analysis and optimization for cooperative communication system. 3. Application of Game theory to the wireless communication systems. 4. Adaptive cellular architecture design, including adaptive frequency planning and sectoring with aids of distributed antenna system and relays. 5. Cross-layer design and optimization for advan.

Research in our lab focuses on signal processing techniques for digital communications systems, including the transceiver algorithms suitable for baseband ICs (such as MIMO detection, equalization, channel estimation, synchronization algorithms for multi-carrier systems, single-carrier systems, and next-generation systems), as well as distributed detection for cognitive radio systems.
