Book Description
It is becoming quite clear that there will be important technological advances in - bile and wireless connectivity, known as third-/fourth-generation (3G and 4G) mobile telecommunications systems. As a result we will be surrounded by ever-growing m- tidomain (technical and administrative) heterogeneous communications in both wired and wireless networks. This resulting environment deals with communication in m- tizoned networks, where people, devices, appliances and servers are connected to each other via different kinds of networks. Networks will be pervasive, ubiquitous, multis- vice, multioperatorand multiaccess. The mobility trend will also be spurred forward by the growing availability of mobile-enabled handheld devices. Mobile systems are expected to provide mobile users with cost-effective, secure, yet ubiquitous service access anywhere and anytime. Users will then continue to enjoy the new-found freedom mobile access provides and will have increasingly high exp- tations of mobility-aware applications that should be capable of seamlessly supporting the mobile lifestyle. The papers in this volume discuss issues from models, platforms, and architectures for mobility-aware systems to security, mobile agent technologies, sensitive com- nications, context awareness, mobile applications and management. They cover both practical experience and novel research ideas and concepts.

Book Description
The beginning of the twenty-first century is characterized by global markets, and the mobility of people is becoming an important fact of life. Consequently, the mobile user is demanding appropriate technical solutions to make use of customized information and communication services. In this context the notion of next-generation networks (NGNs), which are driven by the convergence of the entertainment sector, the mobile Internet, and fixed/mobile telecommunications, is emerging. Such NGNs are aggregating a variety of different access networks and supporting the seamless connection of an open set of end-user devices, and due to the adoption of an all-IP network paradigm they enable a much better integration of voice and data services. Coincidently the buzzword ‘fixed mobile convergence’ (FMC) describes the current trend towards providing common services across fixed and mobile networks resulting in the medium term in the full integration of fixed and mobile telecommunication networks. The adoption of appropriate middleware technologies and the provision of - called service delivery platforms driven by the ongoing innovation in the field of information technologies provides today the technical foundation for supporting terminal, personal and service mobility and thus the implementation of real seamless information and communication services. Furthermore, users are nowadays looking, in light of an omnipresent service environment, for a much higher degree of customization and context awareness in the services they use. The papers in this volume look at these enabling mobility-aware technologies and their use for implementing mobility-aware and context-aware applications.

Book Description
Fast and Efficient Context-Aware Services gives a thorough explanation of the state-of-the-art in Context-Aware-Services (CAS). The authors describe all major terms and components of CAS, defining context and discussing the requirements of context-aware applications and their use in 3rd generation services. The text covers the service creation problem as well as the network technology alternatives to support these services and discusses active and programmable networks in detail. It gives an insight into the practical approach followed in the CONTEXT project, supplying concrete guidelines for building successful context-aware services. Fast and Efficient Context-Aware Services: * Provides comprehensive and in-depth information on state-of-the-art CAS technology. * Proposes a system architecture for CAS creation and delivery, discussing service management and active network layers. * Describes the service lifecycle functional architecture, covering service authoring, customization, invocation, and assurance. * Explains system design considerations and details, system evaluation criteria, test-bed requirements, and evaluation results. Fast and Efficient Context-Aware Services is an invaluable resource for telecommunications developers, researchers in academia and industry, advanced students in Computer Science and Electrical Engineering, telecoms operators, as well as telecommunication management and operator personnel.

Book Description
Doctoral Thesis / Dissertation from the year 2014 in the subject Computer Science - Technical Computer Science, Sir Padampat Singhania University, language: English, abstract: Grid technology is a new paradigm which has the potential to completely change the way of computing and data access. Generally speaking, we could consider the Grid as the new enabling technology to transparently access computing and storage resources anywhere, anytime and with guaranteed Quality of Service (QoS). Grid computing has emerged to cater the need of computingon-demand due to the advent of distributed computing with sophisticated load balancing, distributed data and concurrent computing power using clustered servers. The Grid enables resource sharing and dynamic allocation of computational resources, thus increasing access to distributed data, promoting operational flexibility and collaboration, and allowing service providers to scale efficiently to meet variable demands. The lack of adequate development methods for this kind of systems since the majority of existing Grid applications have been built without a systematic development process and are based on adhoc developments suggests the need for adapted development methodologies. This thesis concern the resource discovery and trust management with security in large size of future grid. An automatic discovery mechanism is needed to find nodes willing to participate in the grid. For mobile grids, a decentralized discovery mechanism is vital to cope with the fluctuating topology and large number of participants. The thesis implemented an Ant based discovery mechanism in which forward and backward ants are used to establish super-grid nodes. The criteria for selecting the super-grid nodes include distance, CPU speed, available bandwidth and residual battery power. After establishing the supergrid nodes among the grid nodes, they collect information about all the resources in a resource table. It consists of grid node id, resource availability, distance from super-grid etc. If any node wants a specific resource, it sends request to its nearest super-grid node from which the node ids matching the request, are returned. The local and global trust values of each node can be estimated based on the factors Job Response time, percentage of correctly received data, Number of successfully finished jobs. These factors can be collected based on the feedback from the user. The trust values can be updated based on the predictive residence time of each grid node. (ie) The node with least residence time (with high mobility) is penalized by reducing the trust value by a step value. [...]
