Topic: | Self-Defending Optical Networks: Optical Channel Protection and Countermeasures |
Abstract: | Fiberoptic DWDM networks transport an aggregate data rate that exceeds Tbps. Because of the huge information rate, optical channels need to be monitored continuously in-service and in-real time. Some of the key channel performance metrics are the Bit Error Performance (BER), and the Signal-to-Noise Ratio (SNR). Currently, these metrics are measured using EDCs and BERTS; EDCs are embedded in the information signal of the channel, and they require many frames of information, and BERTS are specialized equipment used off-service. In this talk, we describe a statistical method which estimates the performance parameters (BER, SNR, NF, Q, and min-max signal levels) of all incoming communication channels simultaneously, in real-time and in-service. In addition, we describe the realization of the method with a simple CMOS circuit and its applicability to multiple channel protection. Finally, we develop strategies for optical network self-defense upon the detection of network intruders. |

Topic: | Information-Centric Networking: Overview, Current State and Key Challenges |
Abstract: |
Information-Centric Networking (ICN), also referred to as content-centric, content-aware or data-oriented networking, is seen as an emerging paradigm that tries to re-focus communications, centering on content access rather than on host-to-host interaction as is the case today. The proliferation of user-generated content and the fact that the vast majority of interactions over the Internet concern media content access has led researchers to think of new communication models in which information/content comes on center stage and is accessed in a location-independent fashion; in addition, the underlying network is aware of the content characteristics and optimizes delivery accordingly. The resulting communications paradigm is receiver-driven, with “time-phased” multicasting and in-network caching being the norm. The network infrastructure becomes more intelligent, with application logic potentially executing within the network in order to support demanding media applications that are not possible today. This presentation will start with an overview of information-centric networking, it will present the state-of-the-art in the relevant research activities and will consider the current state and key challenges. |
Biography: |
Since 2008 I am Professor of Communication Networks coordinating activities in networking and network/service management in the Communication and Information Systems Group at the Department of Electronic and Electrical Engineering, University College London. Before that I was for 10 years Professor of Communication and Information Systems, leading the activities of the Networks Research Group in the Centre for Communication Systems Research at the Department of Electronic Engineering, University of Surrey. I hold a Diploma (MEng equivalent) in Electrical & Mechanical Engineering from the National Technical University of Athens, Greece, and MSc and PhD degrees in Computer Science from the Department of Computer Science at University College London. Before re-joining University College London in the beginning of 2008, I was Professor at Surrey leading research activities in networking and network/service management. Before 1998, I was Senior Research Fellow and Lecturer at UCL, leading research activities in the area of network/service management. At both Surrey and UCL I established and led highly successful research teams while I have also been involved in extensive teaching and curriculum development activities. My research interests focus on networking and network & service management and have included aspects such as traffic engineering, quality of service management, self-organised ad hoc/mesh networks, policy-based systems, autonomic networking, information-centric networking, multimedia service control and object-oriented communications middleware. I have published in all these areas and my publications have been extensively cited, for relevant citations see also my Goole Scholar page. I am on the editorial boards of the IEEE Transactions on Network and Service Management, the IEEE Communications, the IEEE Communication Surveys & Tutorials and the Springer Journal of Network and System Management. I am also involved in a number of international conference program committees. I have consulted for many communications companies in the UK and Europe and have contributed to standardisation activities in ISO, ITU-T, TMF and IRTF/IETF. |

Topic: | Interactive Multimedia Platform for Networked Intelligent Surveillance |
Abstract: | Visual surveillance systems play more and more important roles in many countries for the purpose of public security, although most of these systems just sense environments, send and store videos for online or offline manual observation. Automatic online analysis and alarm is rather difficult because human motion analysis is still a great challenge for complex environments, such as poor illumination, similar backgrounds, object occlusion and various human behaviors. To implement practical intelligent surveillance basing on the above situation, an interactive multimedia platform is designed based on an idea of cooperation between automatic surveillance systems, human observers, mobile robots and cameras for different scenarios. Visual attention models are introduced for security sensitive analysis and vision-audition fusion strategies are proposed for dealing with poor illumination and occlusion. A mobile robot is designed for active vision and active audition for events analysis and all cameras and microphones are networked for event prediction according to their spatial-temporal relations. Lots of indoor and outdoor experiments show that the platform provides us better performances than not only common visual surveillance systems, but also human observation. |

Topic: | Converting Images into NL Text for Multimedia Retrieval |
Abstract: |
Images represent the majority of digital information processed by computers and transmitted via networks. Retrieving the desirable images from databases and especially via internet is a challenging problem. In response to this challenge researchers have developed a variety of methods to accomplish good results. Some of these methods for retrieving images use the color, shape and/or size. Some other methods use image analysis, and other use image annotation (automatic or semi-automatic) techniques. |
