One of the biggest needs of our Information Society is timely discovery of and timely access to relevant information on time. Furthermore, with the advances in computing capabilities of mobile devices, the availability of different kinds of sensors, and the rapid deployment of broadband wireless and fixed networks, users will have access to an unprecedented amount of information and services. Thus mobile devices will play an ever-increasing role, as they will be used for both generating and consuming information. The requirement is to provide seamless and cost effective access to information and services that users need (ubiquitous access to information), regardless of the system they are using.The provision of ubiquitous access at the “wireless edge” will be an important challenge because of the scarcity of resources such as radio spectrum (bandwidth) and energy (battery), as well as the disparity between the resource availability in the wired network and the mobile edge. This will be compounded by the dynamic nature and interaction with its physical surroundings that come with mobility.
One of the major challenges is the design and deployment of services that will provide the users with access to the information and services they need/want efficiently. The focus of the networking group’s research activities is to develop mechanisms that will improve the quality of experience of the users when accessing information and services, especially at the wireless edge, by developing new theories, models and methods for providing the necessary functionality, as well as maximising the usage of the existing infrastructure.
