Such a vision raises questions about how to manage issues like privacy, trust and identity in those environments. In this paper, we review the technical challenges that face pervasive computing environments in relation to each of these issues. We then present a number of security related considerations and use them as a basis for comparison between pervasive and traditional computing. We will argue that these considerations pose particular concerns and challenges to the design and implementation of pervasive environments which are different to those usually found in traditional computing environments. To address these concerns and challenges, further research is needed. We will present a number of directions and topics for possible future research with respect to each of the three issues.

Cellular design considered a free space propagation model supplemented with results from field tested equipment. This model was then used to determine the signal strength that may be achieved in a variety of different environments by applying a classical propagation loss model.

It reports on the experience of using the technique of problem-based learning as a key pedagogical method for teaching practical network design within the context of a Master's program module in data telecommunications and networks at the University of Salford, Salford, Greater Manchester, U.K. A two-threaded approach was adopted that comprised a problem-based learning thread and a conventional lecture thread. The problem-based learning thread within the module comprised sessions designed to place the students in the position of network design consultants who are introduced to scenarios that have a high degree of realism in which a client has specific business requirements that can be met through the adoption of a network solution. In this way, the problem-based learning thread allows the students to develop their design skills, while the lecture thread uses traditional teaching methods to allow students to develop their understanding of key network components and architectures. A formal evaluation of this approach has been carried out and demonstrated a very effective and realistic learning experience for the students. Therefore, the authors propose that problem-based learning is an ideal pedagogical tool for the teaching of computer network design.

The Digital Home Energy Management System (Dehems) project is a wide-scale, government-policy-driven system deployment based on user-driven innovation methodology that assesses user experiences and preferences early on. This approach lets the system provide more value to domestic-energy consumers and effect positive behavior change. Drawing on their experience in developing and deploying the pilot Dehems system and engaging with householders, the authors specify design concerns and the challenges for domesticating energy-monitoring technologies.

Such services offer many new opportunities for organisations such as museums who are constantly striving to improve their overall visitor experience. There is considerable interest in the use of location based services to track visitors as they move around a museum gallery such that information can be delivered that adds value to the exhibit on view. In addition exhibit information can be personalised to the visitor using aspects of their context that relate to their museum visit.

This paper presents a new approach to combating such threats by introducing active routers into the network architecture. These active routers offer the combined benefits of intrusion detection, firewall functionality and data encryption and work collaboratively to provide a distributed defence mechanism. The paper provides a detailed description of the design and operation of the algorithms used by the active routers and demonstrates how this approach is able to defeat a SYN and SMURF attack. Other approaches to network design, such as the introduction of a firewall and intrusion detection systems, can be used to protect networks however, weaknesses remain. Within the paper it is proposed that the adoption of an active router based approach to protecting networks overcomes many of these weaknesses and therefore offers enhanced protection.

Their potential is well recognised in the literature and ongoing technological advances will ensure that their capabilities continue to expand. A key issue for many museums and galleries is to understand the practical realities of developing and operating a multimedia guide to truly realise its potential. In this article, we discuss our experiences developing the mi-Guide multimedia visitor guide at the Museum of Science and Industry (Manchester, UK) and share our experiences of the technical, digital design, content authorship and non-technical, people-related issues that need to be understood and addressed.

From a UK perspective the foundations of this evolution can be traced back to the launch of the UK’s first mobile phone network on the 1st January 1985. The urban environment impacts radio propagation necessitating a greater density of base stations for coverage however also capacity given the density of people within these places. As the urban landscape is constantly changing there is a friction with the cellular network, a new building may block radio signals and/or add new capacity demands, demolition of a building may cause radio interference. In suburban and rural areas there are similar problems plus some unique ones; trees can block signals however this is more likely in summer during and after rainfall due to leaves on trees, therefore taller towers are required. Areas of outstanding natural beauty require base stations to be designed to blend in. Even heritage of buildings has this impact in that you need to design the antennas to be visually blended. Therefore landscape and space play a key role in determining the form and design of a cellular installation; this chosen form then influences the efficiency and upgradability of the cellular network itself. Over its 30 year history the cellular network has undergone many transformations as a result and these will be examined in this presentation. Space, place, and landscape in the history of communications,

The authors, both acknowledged experts in this field, explore the origins of the mobile phone in the UK and its evolution over the following thirty years. Throughout the book they analyse the background developments, such as the licensing of new networks, the emergence of new data services and the technical evolution through TACS, GSM, UMTS and LTE as well as the development of text messaging and the integration of the mobile with the web. Alongside this, the authors explore the design and technical changes to the handsets, including the integration of cameras, the emergence of apps and the trend-setting influence of the iPhone. Ranging from 1G through to the current 4G networks, this book tells you everything you need to know about the development of the mobile phone in the UK. Available from Amberley, Amazon and all good on-line retailers.
