India-UK Advanced Technology Centre (IU-ATC) of Excellence in Next Generation Networks Systems and Services

Lead Research Organisation: University of St Andrews
Department Name: Computer Science


This UK-India consortium-based initiative has been established in direct response to a previous request from the British High Commission in India. The IU-ATC consortium has developed through a series of workshops supported by EPSRC and the British High Commission in India, commencing with a Technical Workshop in January/February 2006. The consortium comprises 8 research-leading universities in UK, 5 leading IITs, major industrial partners in UK and India (including companies such as BT, InfoSys, Wipro, Sasken, and Tejas), and a number of SMEs. The initiative aims to establish the first virtual India-UK Advanced Technology Centre (IU-ATC) in Next Generation Networks, Systems and Services, which will put in place the support infrastructure to facilitate, develop and enable the Digital Economy of both countries. This will be achieved through scientific investigation of the technical and functional requirements of Next Generation Networks through the promotion of industry collaboration with research-leading academic institutions and government departments as part of an initial 30 month Phase 1 of an overall 5-year joint programme between the UK and India. The current proposal builds on the existing and well formed consortium, which has already attracted EPSRC support (Travel Grant GR1, INTERACT 5 GR2), UKTI Grant, GOF, and most recently UKIERI-DST Research Award (S083). The explosive growth in advanced telecommunication networks and multimedia services in the last decade has offered exciting opportunities across a wide range of sectors, including communications, education, entertainment, and health. These opportunities have been successfully embraced within Europe and USA, and there is an increasing need to provide similar opportunities for the rapidly expanding economy of India. However, given India's special requirements, this cannot easily be achieved by transference of existing technical and engineering solutions, and a fundamental rethink is required to adapt or develop novel solutions and provide for research, innovation and wealth creation opportunities between UK and India. The IU-ATC initiative is focused on promotion of the Digital Economy, a priority identified under the recent government Comprehensive Spending Review 2007 . The Digital Economy aims to support research and skilled people to effect early adoption of Information and Communication Technologies (ICT) by a variety of user sectors. Understanding and enabling the impact of information, better positions the UK and India to reap the economic and social benefits offered by emerging Telecommunications Engineering hardware and software together with fixed/wireless/mobile Broadband technologies for low cost sensor and user devices, and service delivery platforms. The challenges in exploiting the promise of the technological advances within NGNs, and achieving their potential performance, economic and social returns, require not only a thorough understanding of the lower layers of the communications networking stack but also a strong ability and interest in exploiting the core technologies for citizen-facing applications. This often implies an appreciation of business and government strategies in specific areas such as healthcare, finance, manufacturing and management and requires close collaboration between academia and industry to realise the full potential.

Kannan G (2009) A Cross Layer Routing Protocol for Multihop Cellular Networks in Wireless Personal Communications

Description The key practical science output of the work has been the examination of the operation, performance and en- ergy efficiency of IEEE 802.11 wireless LAN (WLAN) technology (aka WiFi) for wireless access to Internet services. The key practical engineering output has been the production of an opensource WLAN testbed, with measurement capability, using off-the- shelf equipment. The testbed supports all the commer- cially available variants of IEEE 802.11 (a, b, g and n), in the both the 2.4GHz and 5GHz ISM bands. Our testbed also includes scripts to provide emulations of Voice of IP (VoIP) and Video over IP (ViIP) traffic profiles. Documentation and instructions on operation of the testbed and scripts are included.

Our other output examines the energy efficiency of WLAN applications. The novelty compared to the work of others has two foci:
1. to consider the system level viewpoint, and exam- ine system level energy usage.
2. to relate energy usage to other performance metrics widely used for systems and network management.
The first focus helps us to understand the overall im- pact on WLAN devices and systems when considering energy usage and gain insight into where energy effi-
ciency gains can be made on a system-wide basis. The second focus helps as to understand how both existing (legacy) applications and new applications may be able to use smart adaptation techniques to make energy ef- ficiency gains through software configuration, in com- plement to, but independently of, new energy efficient hardware. We have shown the potential for energy ef- ficiency gains of two orders of magnitude on a system wide basis. We have demonstrated these effects in a repeatable manner on our WLAN testbed.
Exploitation Route Provides insight into operation an d performance of a communication technology that is increasing in its use. Academia and industry will be able to take our performance evaluations in applying these technologies, as well as designing and building evolutions of these technologies.
