    ABSTRACT: The PERFORM project is funded under EC FP7 Program and aims to provide a platform for the remote health status monitoring, classification & modeling, and the personalisation treatment of patient suffering from Parkinson’s disease (PD) and Amyotrophic Lateral Sclerosis (ALS). The remote monitoring of neurodegenerative disease evolution is achieved via micro-sensors worn by the patients at home, forming a local network of specialised devices, which are in turn controlled by a Base Processing Unit (BPU) at patient’s home. The system uses advanced knowledge processing, fusion algorithms, & data mining techniques in order to provide Clinical Decision Support (CDS) for medics & specialist in neurodegenerative disease. This helps with the management & personalised control of the symptoms, for each individual patient, during the evolution of the disease.

    ABSTRACT: In recent years the use of personalized service provisioning applications has been very popular. However, effective personalization cannot be achieved without accurate user profiles. In literature a number of classification algorithms have been used to classify user related information to create accurate user profiles. Nevertheless, there is lack of comparison of these algorithms with classification accuracy of the user profile information. In our previous work [1], we compared four different classification algorithms which are; Naive Bayesian (NB), Instance-Based Learner (IB1), Bayesian networks (BN) and Lazy Learning of Bayesian Rules (LBR) classifiers. According to our results NB and IB1 classifiers outperformed the BN and LBR classifiers with respect to classification accuracy. In this study we compare the performance of NB, IB1, Classification and Regression Tree (SimpleCART), Naive Bayesian Tree (NBTree), Iterative Dichotomister Tree (Id3), J48 -a version of C4.5- and Sequential Minimal Optimization (SMO) algorithms with large user profile data. This study is aimed to find the best classification algorithm for user profiling process. Our simulation results show that, in general, the NBTree has the highest classification accuracy performance with the lowest error rate. On the other hand, we also found that the NBTree has one of the highest time requirements to build the classification model. Therefore, NBTree classification algorithm should be favoured over SMO, NB, IB1, J48, SimpleCART and Id3 classifiers in the personalization applications especially when the classification accuracy performance is important.

    ABSTRACT: Mobile IPv6 and SIP are protocols designed to support different types of mobility. Mobile IPv6 has been used to support mobility in IP networks and SIP has been used for voice over IP applications. It is the signalling protocol of the IP multimedia subsystem (IMS). In this paper both protocols have been simulated and compared in order to observe their performance for voice over IP (VoIP) applications. In this paper the architectures proposed by researchers in order to combine mobile IPv6 and SIP have also been investigated and compared to analyse their advantages and disadvantages. A network scenario, running mobile IPv6 and SIP for IMS, has also been simulated in order to evaluate the performance offered by the two protocols and to compare them with the results from the simulation of the pure mobile IPv6 and SIP architectures. The comparison shows that the combined scenario offers better performance similar to the one obtained using only mobile IPv6 with route optimization. The scenario simulated was also compared with the integrated architectures for mobile IPv6 and SIP that were investigated.

    ABSTRACT: The ePerSpace project is developing and implementing a generic distributed networked system with wide ranging applications, accessible at home and globally anywhere else outside home. The project is creating an open, interoperable and trusted integration framework to create network enabled audiovisual systems and home platforms where home and personal devices can seamlessly work together providing personalised services, provisioning content adaptation, and managing service platforms. Using the personalisation information the system can recognise and form specific user communities towards which specific services can be directed. The paper presents the main concept and components of the system such as: the global service manager (GSeM) which handles service providers, users and the residential gateways (RGs), and local service manager (LSeM), which manages home and personal devices inside the home area network (HAN), and communication between GSeM and LSeM

    ABSTRACT: The paper describes development of a generic architecture for the intelligent reconfiguration of the wireless mobile networks within the EC funded Framework V CAST Project. The CAST demonstrator, currently being developed and integrated, is intended to evaluate some of the fundamental concepts of the proposed architecture, within the technological constraints presently available. Here, we present a generic distributed architecture and discuss problems associated with the organic-based intelligent support, network management, resource optimisation and control, and object orientated reconfiguration of resources.

    ABSTRACT: In this paper, a novel method for improving the spectrum efficiency of multi-layer cellular systems, by means of prioritisation based on the user mobility behaviour and service application has been proposed. The proposed system is shown to have a higher efficiency over a wider range of offered traffic, in comparison to the conventional FIFO queuing. Computational results suggest that using this new scheme, system capacity for handover voice calls at 2% dropping rate can be improved by as much as 27% compared with FIFO. This benefit came at the expense of some increase in the dropping rate of low priority calls. The improvement in capacity also reduces with service priority.

    ABSTRACT: We present our vision of the software radio (SR) concept. To the author's knowledge this vision of an intelligent reconfigurable network encompasses and adds to the main SR concepts presented to date, namely SR/SDR, re-configurable radio systems and networks, and cognitive radio. The newly proposed architecture and supporting technology provides a flexible way to introduce re-configurability into any network node and protocol layer of a network fixed or mobile, while simultaneously providing a structured framework in which re-configurability can be introduced and hence networks can evolve. This concept has provided a solid foundation and plays a central role in providing a suitable context in which to examine reconfigurabilty issues in the mobile terminal and base station. We believe that this concept has the potential to help the telecommunications industry in facilitating; the introduction, development and harmonization of reconfigurability within existing and future fixed and mobile networks

    ABSTRACT: This paper presents a possible solution to the intelligent evolution of mobile systems using a complex organic distributed architecture (CODA), which supports intelligent reconfiguration of all system components. A key feature of this architecture is the deployment of multiple warehouses. The warehouses store data in a variety of ways depending on the type of intelligence, required. On line analytical processing (OLAP) software is used to monitor and control data in the system. An effective system of filters and wrappers ensures that data is secure. A system of feedback loops ensures that information travels through the system quickly and effectively

    ABSTRACT: This paper examines some of the limitations of existing handover schemes and the potential performance and efficiency gains that can be achieved through hybrid variants that utilise neural networks. The virtual connection tree (VCT) is chosen as a candidate handover scheme because it statistically demonstrates a fast handover methodology that uses resource pre-allocation to maintain the QoS requirements for wireless ATM traffic. A hybrid multicast re-routing; scheme is introduced which aims to utilise the available bandwidth more efficiently and consequently to handle a higher number of concurrent calls

    ABSTRACT: This paper demonstrated the potential of the novel technique of the active predistortion linearisation. In comparison to the competitive methods, the proposed technique has the distinct advantage of reducing all the components of IMD distortion uniformly and over a wide frequency range, without significantly affecting the power efficiency
