Directions of activity

 

Basic directions of the Laboratory activity are development of theoretical foundation for analysis and synthesis of distributed information transmission networks, and practical implementation of large-scale projects concerning with distributed computer and communication networks.

The theoretical researches are carried in the following directions:

·        Development of theoretical foundation for design of infocommunication networks including both terrestrial fiber-optic and copper channels, and wireless radio and infrared communication lines.

·        Development of analysis and synthesis methods for wireless local area and regional networks controlled by IEEE 802.11x and IEEE 802.16 protocols.

·        Development of design methods for integrated information systems, using visual modeling methodology.

·        Development of methods and algorithms for topology synthesis and optimal routing in telecommunication networks.

 

MAIN RESULTS

 

In 2004, the Laboratory continued the fundamental researches related to extreme graph theory, queuing networks theory, and reliability theory. Moreover, the field experiments with various physical media (fiber-optical, radio, satellite communications), operational environments and various network architectures were carried on simultaneously.

The following main results have been obtained:

·        Basing on original topology synthesis algorithms and methods for connectivity probability evaluation and optimal route choice, the Laboratory has finalized the first version of automated design system for information transmission networks.

·        The Laboratory has developed novel analytical and simulation methods for modeling and designing broadband wireless networks, including:

–          Stochastic models for comparative study of distributed and centralized control in regional wireless networks;

–          Centralized control algorithm adaptive to experienced load for IEEE 802.11 networks and the algorithm optimization with usage of Markov models of network operation;

–          Methods for performance evaluation of IEEE 802.11 local area networks and study of packet fragmentation mechanism efficiency in case of correlated channel failures.

·        A novel method for integrated information system design has been developed on the base of visual modeling methodology and with usage of structural and object-based approaches. The method has become a foundation of large-scale organizational structures. Inter-document relation search algorithm has been developed on the base of shortest path search in large-scale graph.

Theoretical results in the area of distributed network analysis and design have been used as a basis for development of large-scale telecommunication network projects. Specifically, the scientific study results have been adopted in the following projects:

·        Extension of the Radionet cellular radio-modem network to provide an access to Internet for Moscow institutions of science, culture, and education. The Laboratory has finalized the deployment of the terrestrial fiber-optic backbone network joining the Radionet network’s base stations by implementation of two channels: IITP of RAS – Moscow State University – Ě9 and IITP of RAS – High-rise building at Kudrinskaya square with 100-Mbps information transmission rates. IITP-of-RAS routing node has been installed at M9 trunk exchange.

·        Development of pilot versions of high-rate wireless routers for bundling regional wireless networks, which exceed present domestic and foreign analogues.

·        Development and extension of telecommunication networks of Russian Ministry of Transport and Russian Road Agency. Development of an integrated information system for Presidium of RAS.
