Keynote title:

"Satellite Networking: Evolution and the Future"

Satellite communications has played a significant role over the years both in military and commercial environments in a net- centric mode. The satellite network provides a complimentary solution to terrestrial mobile networks in emergency and disaster recovery, digital broadcasting, m- health and m-learning covering both urban and rural areas. This talk provides an overview of satellite communication systems design evolution in real world deployment with personal experiences and examples. The presentation covers systems that have been developed based on fixed and mobile services, switching technologies (e.g.circuit/packet/ATM/IP), processing options with on-board/repeaters, DAMA, and applications anywhere from pure voice to the current multimedia for Information Communication Technology (ICT) services. The historical era of Ka-band systems and the mobile satellite systems (MSS) and the lessons learned will be highlighted.

Digital Video Broadcasting (DVB) technologies and service applications using DVB standards via satellite including DVB-S/S2/RCS/RCS+M, and DVB- SH, for hand held devices and other technologies such as DOCSIS for satellite are presented. This dicussion is followed by research in the area of hybrid satellite-wireless networks with examples. Some of the technical challenges such as QoS, crosslayer protocol designs, propagation effects mitigation, mobility management, and interoperability for system realization are emphasized. A brief report on the current standard activities from organizations such as ITU- R, ITU- T, ETSI and IETF is presented. The presentation concludes with current trends on terabit satellites, O3b, satellite component for 5G, and research directions for the role of satellites for future networks.


Dr. Sastri Kota Dr. Sastri Kota, President of SoHum Consultants and Adjunct Professor, University of Oulu Finland has made transformative contributions to satellite communications and networking in both military and commercial environments. He began his career as a lecturer at IIT Roorkee, India in 1966. Since then he has held several management, technical, and senior scientist positions at Harris, Loral, Lockheed Martin, SRI international, The MITRE, XEROX and CSC Corporations. He provided leadership in International Standards as Head of the US delegation and Chair of ITU-R working group; Chair of Wireless ATM of ATM Forum and supported the satellite activities of IETF. He has authored/co-authored: Broadband Satellite Communications for Internet Access, Emerging Location Aware Broadband Wireless Ad Hoc Networks, Satellite TCP/IP in High Performance Networking, Trends in Broadband Networking in Wiley Encyclopedia of Telecommunications, and Modeling and Simulation Environment for Satellite and Terrestrial Communication Networks. He has published and presented more than 200 papers in conference proceedings, and journals and he holds US patents in bandwidth allocation and cross-layer designs. He conducted lecture series and tutorials on computer networking, broadband satellite networks, digital videobroadcasting at MILCOM, IEEE, and AIAA conferences; as well as several international universities. His research areas include Internet of Things (IoT); Broadband satellite and hybrid-network architecture; QoS and cross layer designs; terabit satellite networks; satellite component over 5G; cooperative communications; digital video broadcasting; and signal processing. Dr. Kota served as a guest editor of special issues for IEEE Communications Magazine, IEEE Wireless Magazine, IEEE VTS magazine, Int’l Journal of Satellite Communications and Networking, Space Communications- an Int’l Journal, and Int’l Journal of Wireless Information Networks. He is a member of the editorial boards on the Int’l Journal of Satellite Communications and Networking, and the Space Communications Journal. He served as the Unclassified Technical Program Chair of MILCOM 2007, symposium chair and co-chair of IEEE GLOBECOM 2009, 2006, 2002, 2000, and Technical chair of ISWPC 2007and served in the Technical committees of ICC, PIMRC, WCNC and IWSSC. Dr. Kota holds a Ph.D from University of Oulu, Finland, an Electrical Engineer’s degree from Northeastern University, Boston, US; an MSEE from IIT Roorkee, and a BS in Telecommunications from BITS, Pilani, India. He is the recipient of the Golden Quill and Enginnering awards from Harris Corp, Publication awards from Lockheed Martin, and the ATM Spotlight award from the ATM Forum. He is a Life Senior Member of IEEE and an Associate Fellow of AIAA.
