Join the IEEE Communications Society Monday evening, 22 April 2013, to hear Dr. Anthony Chuan, Huawei Technologies, present “Distributed Mobility for Future Mobile Internet”.
Cellular networks, which currently serve 6 billion telephones and mobile devices globally, have employed centralized control with different network functions arranged in a hierarchy. The Internet, however, has employed distributed control functions in a more flattened, i.e., less hierarchical structure. Despite the large amount of standards work on Internet mobility in the Internet Engineering Task Force (IETF) focused primarily with centralized mobility, the deployment to the mobile Internet is still slow, and a fundamental change to distributed mobility is needed.
Mobility management with centralized mobility anchoring in existing hierarchical mobile networks is quite prone to suboptimal routing and issues related to scalability. Centralized functions present a single point of failure, and inevitably introduce longer delays and higher signaling loads for network operations related to mobility management. To make matters worse, there are numerous variants of Mobile IP in addition to other protocols standardized outside the IETF, making it much more difficult to create economical and interoperable solutions. The existing mobility management standards in IETF, the issues of mobility management for the future mobile Internet, the trend of the mobile Internet and the proposed distributed mobility at IETF are explained.

Wednesday, January 16, please join the MTTS at Ciao Wireless to hear Earl Cox, program manager at AeroVironent, present Adoption of the DDL Waveform for the most widely deployed UAV in the World (19,000 airframes).
Small Unmanned Aircraft Systems (SUAS) such as the Army’s RQ-11B Raven have become a vital part of a soldier’s equipment since the early 2000’s. They help to cut through the Fog of War by providing the soldier with a vantage point to observe his or her surroundings while remaining far away from the danger. In order to accomplish this, however, the soldier needs to be able to communicate with the aircraft, both to control it and to get the information that it has.
A major improvement in the SUAS filed that Earl will discuss is an interoperable data link called the SUAS Digital Data Link (SUAS DDL or just “DDL”). The Army has adopted this data link as its standard waveform for all of its Unmanned Aircraft weighing less than 30 lbs.
This presentation will describe the waveform and how it can be used to work with Small Unmanned Aircraft to keep American and allied soldiers safer.

Wed, 28 Nov 2012 at 7pm, Dr. Christopher Silva, Ph.D., IEEE Fellow, describes highly accurate baseband time-domain measurement and modeling techniques for non-linear communications components and systems.
The increasing demands for performance, mobility, and services in difficult physical channel and frequency allocation environments, in both commercial wireless and military contexts, pose formidable new challenges to communications designers. Current activity in these areas has especially focused on the system level or behavioral modeling of solid-state power amplifiers, with concomitant efforts on efficiency enhancement and distortion compensation, the latter in the form of predistorters, linearizers, and equalizers. Refined nonlinear measurement and modeling approaches will be required to successfully support these efforts, which will only escalate in difficulty with the use of increasingly complex and broader bandwidth signaling schemes.
This presentation introduces and describes highly accurate baseband time-domain measurement and modeling techniques applicable to nonlinear communication components and systems having bandwidths ranging up to several GHz This method provides a powerful set of tools, and numerous benefits for the state-of-the-art nonlinear modeling and distortion compensation of communications systems.
About the Speaker

MTTS hosts IEEE Fellow Dr. Arun K. Bhattacharyya Wed 16 May 2012 at Ciao Wireless to present “Efficient Shaped Beam Synthesis in Phased Arrays and Reflectors”.
Shaped beam array synthesis invites considerable attentions because arrays offer the highly desirable “in-orbit reconfigurability” for communication and broadcasting satellites. This talk presents an overview of commonly used beam shaping algorithms, followed by the Projection Matrix Method of synthesis. The Projection Matrix method relies on orthogonal projection of the desired far field intensity vector onto the space spanned by the far field intensity vectors of the array elements. The method is employed successfully for a reflector surface synthesis and is shown to be several times faster than the gradient search method commonly used for beam synthesis. Numerical results for array and shaped reflector syntheses are shown and advantages are discussed. High efficiency horns as an array element will also be reviewed.

Please join Aerospace, Life Members, and Microwave Societies joint presentation of Computational Modeling of Partially-Ionized Gases for the Assessment and Mitigation of Material Degradation in Electric Rocket Propulsion by Dr. Ioannis (“Yiangos”) G. Mikellides, NASA Jet Propulsion Laboratory.
Electric propulsion (EP) embodies several plasma rocket technologies that can enable new science missions for NASA. Over the last two decades two (mN-class) EP systems have emerged as primary candidates for several proposed science missions, mainly due to their superior performance and proven record in space flight: the Ion and Hall thrusters. As NASA looks ahead to increasingly ambitious science goals however, missions become more demanding of the life of the propulsion system. Therefore, by contrast to the early years of development of these thrusters, when the emphasis was on propulsive performance, the focus today is shifting towards extending their service life.
Two major difficulties emerge as a result of the increasing demand for extended thruster operation. First, the degradation of these thrusters occurs largely due to ion bombardment of the material surfaces. Thus, the problem requires an understanding of not only the complexities of the ionized gas that persist in these thrusters but also of the close coupling that exists between the gas and the thruster materials. Second, since the service life of EP has been customarily demonstrated through life tests in vacuum facilities, both the cost and time associated with such tests are expected to rise. Whereas some cost-capped NASA missions may be able to absorb these costs, launch window opportunities and mission timelines may simply rule out a multi-year life test. It is therefore becoming increasingly apparent that some combination of analysis and test must be adopted in the life qualification process of EP. Inevitably, computational modeling of EP has been receiving increasing attention at NASA.
Considering all potentially life-limiting mechanisms in Ion and Hall thrusters two are of primary concern: (a) the erosion of the acceleration channel in Hall thrusters and, (b) the erosion of the hollow cathode, a component that is necessary for the operation of both types of thrusters. The physical processes leading to material wear in these devices are uniquely challenging. In this presentation the driving plasma physics will be elucidated based on insight gained from advanced numerical simulations at the Jet Propulsion Laboratory (JPL). Recent breakthroughs on erosion mitigation will also be presented, which, after more than three decades
About the Speaker
Dr. Mikellides received his doctoral degree in Aeronautical and Astronautical Engineering in 1999 from the Ohio State University with concentration in plasma propulsion and computational magnetohydrodynamics. Since 1992 he has been performing numerical simulations of ionized gases that have spanned a broad range of temporal and spatial scales, in problems such as plasma processes within a GW-level, high-pressure (>1000 atm) discharge chamber and hypersonic nozzles, ablative thrusters, fusion-powered subsonic/supersonic plasma flows through magnetic nozzles, rarefied EP plumes and, more recently, X-ray-radiating astrophysical plasmas. Since joining the EP group at JPL in 2004, Yiangos has developed the first comprehensive 2-D computational model of the partially-ionized gas in hollow cathodes and the first 2-D model of Hall thrusters with a computational mesh that is closely aligned with the applied magnetic field. Yiangos is an Associate Fellow of the AIAA and has been the recipient of multiple awards for his computational work in EP including the NASA Exceptional Engineering Achievement Medal and the Lew Allen Award for Excellence in Scientific Research. He is a Sr. Engineer at JPL with joint appointments in the Engineering and Science Divisions. He has authored/co-authored over twenty-five peer-
