Wireless Communications and Networking
In the last 25 years, wireless communications has emerged as one the most dynamic and exciting areas in telecommunications. Wireless systems like GSM and CDMA, developed in the late 80s and early 90s, and undergoing continued refinement, have enjoyed tremendously successful widespread deployment. Newer technologies developed in the late 90s and around the turn of the century, are now exploding in popularity, including 3G mobile networks and Wireless LAN (especially in their Wi-Fi incarnations) systems. While 3G mobile networks have evolved from the mobile telephony world, Wireless LAN systems have come from the data communications world, and surprised many with their great market success. Research activities include: IP mobility protocols (MIPv6, route optimization, redirection-based protocols, etc.) 3G/WLAN integration (network architectures, teletraffic analysis, etc., for optimizing design of integrated 3G and WLAN or GSM and WLAN systems where WLAN covers hotspots while 3G/GSM provide wide-area coverage), WLAN performance, and security for wireless networks.
