Research Interest

My primary interests are in the areas of high-speed and wireless networks with particular emphasis on the impact of these new technologies on the network and higher layer protocols and applications. Building on the past extensive experience in protocol and architectural issues of the existing telephone network, I currently interested in routing and security issues in IP Telephony. I am  interested in P2P networks with particular emphasis on incentives for resource contributions. I am also interested in mobile ad hoc and sensor networks, particularly, in challenges in and applications  of vehicular ad hoc networks. Finally, I am interested in the protocols and architectural issues in next generation wireless and cellular networks.
