Performance analysis of a security architecture for active networks in Java

Internacional Association of Science and Technology for Development - IASTED, Benalmadena, Spain: 8-10 Septiembre, 2003.Active network technology supports the deployment and execution on the fly of new active services, without interrupting the network operation. Active networks are composed of special nodes (named Active Router) that are able to execute active code to offer the active services. This technology introduces some security threats that must be solved using a security architecture. We have developed a security architecture (ROSA) for an active network platform (SARA). Java has been used as programming language in order to provide portability, but it imposes some performance limitations. This paper analyses the penalty of using Java and proposes some mechanisms to improve the performance of cryptographic implementations in Java.Publicad

Mobihealth: mobile health services based on body area networks

In this chapter we describe the concept of MobiHealth and the approach developed during the MobiHealth project (MobiHealth, 2002). The concept was to bring together the technologies of Body Area Networks (BANs), wireless broadband communications and wearable medical devices to provide mobile healthcare services for patients and health professionals. These technologies enable remote patient care services such as management of chronic conditions and detection of health emergencies. Because the patient is free to move anywhere whilst wearing the MobiHealth BAN, patient mobility is maximised. The vision is that patients can enjoy enhanced freedom and quality of life through avoidance or reduction of hospital stays. For the health services it means that pressure on overstretched hospital services can be alleviated

The role of the multinational firms on the producer services sector: repercusions for peripheral regions.

The spatial polarisation of services is one of the explanations for present regional disparities. A new international division of labour based on Business Services has appeared, in which multinational firms play an important role. This paper aims to examine the repercussions of the behaviour of firms in the advanced business services (ABS) sector on peripheral regions. Particularly, we analyse the case of Andalusia – a region situated in a “central area”, the European Union, but characterised as peripheral-. Using direct research – interviews carried out with a representative sample of enterprises -, we study the impact of these multinational firms, not only from the point of view of the companies which offer these services in Andalusia, but also from the point of view of demand – enterprises which use these services -. Multinational firms Business advanced services Peripheral regions Uneven regional development Andalusia

Prototyping Telematic Services in a Wireless Vehicular Mesh Network Environment

International audienceNext generation telematic services are expected to play a key role in future automotive applications. In order to achieve strong integration between the services and the underlying network infrastructure there is a need for both simulation and emulation of the entire system. This paper presents a combined simulation and emulation approach for telematic services prototyping in an emulated wireless vehicular mesh networking environment. The ns-3 wireless mesh model, SUMO vehicular mobility model and different telematic services are integrated to demonstrate high scalability and flexibility of the proposed approach

Integrating Cloud Computing with Next-Generation Telematics for Energy Sustainability in Vehicular Networks

This research focuses on new approaches to enhance the economic viability of newer hybrid/electric vehicle technology utilizing a telematic and cloud computing framework. First, an economic foundation is proposed that rewards drivers for energy efficient driver behavior in units of energy based on a predefined standard. Next, a service model is presented that allows drivers to transfer information regarding their energy efficiency through a telematic and cloud computing network. Based on existing cloud computing technology and telematic standards, a network architecture is proposed to transfer this information to service integrators and content providers that can use this information to create vehicle energy resource management capabilities for vehicle users and fleet owners. Such an architecture would enable drivers or fleet owners to redeem energy units for monetary or promotional incentives, thereby realizing more economic value for the vehicle investment
