WiSNet: Welcome to Wireless and Secure Networks Lab

Welcome to Wireless and Secure Networks Lab

Wireless and Secure Networks (WiSNet) Research Lab at the NUST School of Electrical Engineering and Computer Science (SEECS), National University of Sciences & Technology (NUST) conducts research in two broad domains; IP-based Wireless Networks, and Network/information security. In the former domain, WiSNet is currently investigating projects pertaining to network performance analysis and enhancement, high-throughput communication, fair and efficient medium access, resilient and energy-efficient routing, and wireless multimedia. In the latter domain, WiSNet focuses on network- and host-based intrusion detection, malware and vulnerability analysis, network forensics, and information hiding.
