During the past five decades, satellite communications due to features such as global coverage, bandwidth flexibility, broadcast and multicast has played a major role in providing fixed and mobile services for both voice and data applications. With the growing demand of multimedia services and the exponential growth of the Internet, various broadband access technologies have been developed. Satellite communication has been a viable alternative to such access technologies. e.g. ADSL, Cable and Optical fiber. Satellite also plays a significant role in core networking for system of systems architectures. Although several broadband satellite network initiatives became the victims of changing economic trends, new applications such as support of email, fax and Internet access on airplanes, fast trains, during disaster recoveries and tsunami warning systems dictate the development of converged satellite and wireless network infrastructure.

In his keynote, Dr. Sastri Kota will address the satellite communications evolution and the current status of the GSO and NGSO network systems at different frequency bands, supporting multimedia and Internet access for fixed and mobile services. He will also provide an insight into IP based satellite networking and technical challenges that must still be addressed such as Quality- of- Service (QoS), multicast protocols, transport protocols and security. He will share his vision of the next wave of network architectures and possible technologies with emphasis on standards development to meet system interoperability requirements.

Dr. Sastri Kota is a Senior Scientist at Harris Corporation. During the past 30 years he held various technical and management positions and made significant contributions to military and commercial satellite communication systems. His research and development interests span the areas of broadband network architectures-IP and ATM, protocol design and analysis, traffic management and QoS, satellite IP, wireless and Mobile Ad Hoc networks, cross layer protocols and performance modeling at Loral Skynet, Lockheed Martin, SRI International, Ford Aerospace, the MITRE Corp., Xerox Corp., and Computer Sciences Corp. He was on the faculty of the Electronics and Communication Engineering Department of Indian Institute of Technology (IIT), Roorkee. He is an active participant at various Standardization Organizations and Industry Forums; ITU, IETF, ATM Forum, and TIA. Currently he is the US chair for the ITU-R, Working Party 4B and International Rapporteur for Ka-Band Fixed Satellite Systems. He was the chair for the Wireless ATM Working Group and ATM Forum Ambassador.

Dr. Kota is the principal author of the book Broadband Satellite Communication for Internet Access, Kluwer Academic Publishers, co-editor of the book Emerging Location Aware Broadband Wireless Ad Hoc Networks, Springer and has contributed book chapters to Encyclopedia of Telecommunications, John Wiley & Sons, High Performance TCP/IP Networking, Prentice Hall, and Modeling and Simulation Environment for Terrestrial and Satellite Networks, Kluwer Academic Publishers. He has published over 100 technical papers in journals or conference proceedings. He served as a guest editor for the IEEE Communications Magazine, Special Issues on Satellite ATM Architectures and Broadband Satellite Network Performance and International Journal of Satellite Communications and Networking, Special Issue on Satellite IP QoS .He currently serves on the editorial boards of the International Journal of Satellite Communications and Networking (Wiley Interscience), and the Space Communications (IOS Press). He also served as technical chair, member of organizing committees and technical program committees of numerous IEEE, AIAA, SPIE and ACM conferences and workshops.
