  • Ubiquitous Computing - Test Bed and Applications., Sponsored by Department of Information Technology (DIT), Govt. of India, New Delhi.

    Project Started: 1st March 2007
    Duration of the project: 3 Years
    Amount : Rs. 97 lakhs


         Ubiquitous computing is the trend towards increasingly ubiquitous (another name for anytime, anywhere), connected computing devices in the environment, a trend being brought about by a convergence of advanced electronics and particularly, wireless tech- nologies and the Internet. Ubiquitous computing devices are not personal computers as we tend to think of them, but very tiny - even invisible - devices, either mobile or embedded in almost any type of object imaginable, including cars, tools, appli- ances, clothing and various consumer goods - all communicating through increasingly interconnected networks. Ubiquitous computing is integration of Distributed Systems, Mobile Networking, and Embedded Smart Devices. The issues of the distributed sys- tems and mobile networking are still the issues in ubiquitous computing along with the new issue arising from embedded smart devices communication.

  • Design and Development of a Security Scheme for M-Commerce applications,, Sponsored by Department of Information Technology (DIT), Govt. of India, New Delhi. .

    Project Started: 1st October 2004
    Duration of the project: 2 Year
    Amount : Rs. 27 lakhs


         Internet security is foremost in the minds of businesses as well as consumers. What can we do to provide a secure environment for online transactions? The last couple of years have seen a big push by the telecom industry to accelerate the use of wireless technology in providing distributed computing and internet facilities. New technologies abound - WAP, i-mode, J2Me, VoiceXML, Bluetooth, GPRS, MMS and Wireless LANs, to name a few. While these new services are beset by the problems of introducing new technology and the current economic pressures, slowly but surely they will start to impact on how we do business, thus setting new challenges for the IT functions in many organizations.

    Mobile communications is now considered a relatively mature technology with the move from second to third generation systems, and with its high consumer acceptance. Clearly, as the level of involvement increases, so does the responsibility and potential liability for loss. The security concept built and applied around the service will depend on how the service is configured, but must also ensure that liability is established where an interface occurs with another party.

    Bearing this in mind, the three basic security components are:
    Transaction:protecting the transaction parties and their data by providing an acceptable level of security
    Information: protecting valuable and sensitive information about customers
    Infrastructure: protecting the network infrastructure from attack.

    In this proposed project, we envisage to carry out research and development in the area of mobile commerce security. We are planning to develop three Application Programmable Interfaces (APIs) namely Authentication Services API, Cryptographic Services API and Key Management Services API.
  • Development of MPLS Net-box, Sponsored by Central Research Laboratory, BEL, Bangalore..

    Project Started: 1st July 2002
    Duration of the project: 1 Year
    Amount : Rs. 25 lakhs


         The strength of the Internet has been its immense scalability and adaptability to accommodate a seemingly unceasing portfolio of applications. In this tradition of adaptability, Multiprotocol Label Switching (MPLS) is the latest technique being implemented in the Internet core. MPLS provides a virtual path capability between packet (label) switches to efficiently carry differentiated services across the Internet. Additionally, MPLS has been enhanced with the capability to precisely engineer traffic tunnels to avoid congestion and more fully utilize all available bandwidth. The greatest strength of MPLS is its seamless coexistence with IP traffic and its reuse of proven IP routing protocols.

    The Multi-Protocol Label Switching (MPLS) has been widely identified as a new tool to help service providers meet the often-conflicting challenges of increased predictability, growth in revenue, and cost reduction. MPLS's connection-oriented nature that provides an ability to increase IP service predictability, create differentiated IP services, and potentially reduce operation costs in IP-centric and multi-service networks.

    To achieve all of this, MPLS combines a variety of functions from both IP and ATM.Specifically, MPLS adds enhancements to IP routing protocols to make them connection-oriented. In short, MPLS aims to provide a Connection-Oriented Link Layer (COLL) for IP that results in reliable and predictable forwarding of IP traffic, and that enables traffic engineering, congestion management, optimized end-to-end transmissionrecovery, and differentiated IP services. Further, MPLS, when augmented with a QoS framework such as that specified in the IETF's Differentiated Services model, may enable deterministic QoS in IP-centric networks.

  • "Design and Development of Routing Intelligent Mobile Agents for the INTERNET Routing", Sponsored by Cisco Systems Ltd., USA..

    Project Started: 15th February 2001
    Duration of the project: 1 Year
    Amount : US 65,000 Dollars


         The Internet is extremely diverse, in terms of both the technologies that from the network and applications that use it. Today, the range of traffic management options is fairly limited in the Internet. The switches and routers increasingly have some support for packet classification and scheduling, these capabilities are often only used in simple ways, such as filter out certain types of traffic, to do some simple prioritization of flows, or to implement some QoS mechanisms, etc. As long as routers are closed boxes with set of standard protocols, it is unlikely that the Internet can meet the future end-user requirements and the highly competitive service providers plans.

    To meet the future routing requirements, we propose to design more flexible, quickly adaptable to the changes, reliable, scalable, and rapid stabilizable routing strategies. This project is aimed at building the Routing Intelligent Mobile Agents (RIMAs) for the routing in the Internet.

  • "Design and Development of an IP-based Multimedia Network Service Platform (MNSP)", Sponsored by Central Research Laboratory, BEL, Bangalore.

    Project Started: 1st August 2000
    Duration of the project: 1 Year
    Amount : 8.75 Lakhs Rupees


         Recent advances in distributed systems and transportable software and increasing demand for better quality-of-service (QoS) control in multimedia service networks are driving a reexamination of network software architectures. We believe that the development of Multimedia Network Service Platform (MNSP) is the solution and represents a key research challenge to the networking community. The MNSP is a system independent service platform which would be easily portable on any networking environment. The proposed platform must support a set of application interfaces (APIs) for resource control and management to meet the required QoS guarantees of the multimedia applications.

    The project duration is 12 months. During the period we propose to carry-out a feasibility study to built a sophisticated Multimedia Network Service Platform to support different type of multimedia applications and develop a prototype MNSP for Voice-over IP and Video-on-Demand applications.

    Our feasibility study focuses on developing new network architectures that support service creation, QoS control, and the joint allocation of computing and communications resources. This provides a new opportunity to reconcile the perspectives of the computing and communication communities.

  • " Protocol Engineering and Technology Unit (PET-Unit)", sponsored by Northern Telecom (NORTEL), Canada.

    Project Started: 1st October 1998
    Duration of the project: 5 Years
    Amount : 100,000 US dollars


        Nortel Networks, Canada., has given this amount as a research-seed money for five years. Regarding the deliverable for this research grant, PET-Unit and SEAL, Nortel Networks, will decide every year.

    In case new projects have been proposed to Nortel Networks under PET-Unit, the Nortel is ready to provide additional funding to the new research programme during this period.

    (a) Deliverables for the Year (October 1998 - September 1999): Design and development of a Quality of Service adaptation and Mixers Algorithms.
    The proposed adaptation procedures are to provide desired QoS in Mixed wired and wireless networks which allow the system to recover automatically, if possible from QoS violations by identifying a new configuration of system components that might support the initially agreed QoS and by performing a user transparent transition from the original configuration to the new one.
    The proposed approaches, together with suitable negotiation mechanisms, allow us:

    (i) to reduce the probability of QoS violations which may be noticed by the user, and thus to increase the user confidence in the service provider,

    (ii) to improve the utilization of the system resources and thus to increase the system availability, and

    (iii) to deliver the data in time in case of critical connection abort situation.

    (b) Deliverables for the Year (October 1999 - September 2000): Designing the Self-Stabilization procedures for the BGP-4 implementation on a Router.
    To manage traffic across this complex, extensive and geographically dispersed network, more and more corporations are splitting their internal network ASs into multiple ASs that are linked by a backbone of routers running BGP-4. Within each AS, devices running Enhanced Interior Gateway Routing Protocol (Enhanced IGRP) and Open Shortest Path First (OSPF) continue to route traffic among subnetworks. However, propagation of table updates among these routers remains internal to a given AS domain. In this project we propose some of the performance studies on Routing system and design faster self-Stabilization procedures for BGP-4 implementations.

  • "Education-on-Demand system over Virtual Private Networks", Sponsored by Dept. of Education, Ministry of Human Resources Development (MHRD), Got. of India.

    Project Started on: 4th January 1999
    Duration of the project: 3.5 Years
    Amount : 5 Lakhs rupees


         Researchers have developed and are continuing to develop technologies that can make Internet data transmission more efficient and provide additional bandwidth. Some of the more promising techniques include Internet switching and fast modems, as well as Integrated Services Digital Network(ISDN) and Digital Subscriber Line (DSL) technologies. Virtual Private Networks (VPNs) transmit data via the Internet, rather than expensive traditional private networks. A VPN provides network-to-network or remote-user-to-network connectivity via an encrypted tunnel through the public Internet. Data must be encapsulated within an IP packet before it can be sent across a VPN. Network owners use various encryption and authentication schemes to provide security.

    The proposed Education-on-Demand system is a VPN based Internet service. It has the multimedia data abstracted from the various subjects in the form of multimedia documents which may be available even in the multimedia databases.
