M2M Communications: A Systems Approach

Abstract: A comprehensive introduction to M2M Standards and systems architecture, from concept to implementationFocusing on the latest technological developments, M2M Communications: A Systems Approach is an advanced introduction to this important and rapidly evolving topic. It provides a systems perspective on machine-to-machine services and the major telecommunications relevant technologies. It provides a focus on the latest standards currently in progress by ETSI and 3GPP, the leading standards entities in telecommunication networks and solutions. The structure of the book is inspired by ongoing standards developments and uses a systems-based approach for describing the problems which may be encountered when considering M2M, as well as offering proposed solutions from the latest developments in industry and standardization.The authors provide comprehensive technical information on M2M architecture, protocols and applications, especially examining M2M service architecture, access and core network optimizations, and M2M area networks technologies. It also considers dominant M2M application domains such as Smart Metering, Smart Grid, and eHealth. Aimed as an advanced introduction to this complex technical field, the book will provide an essential end-to-end overview of M2M for professionals working in the industry and advanced students.Key features:First technical book emerging from a standards perspective to respond to this highly specific technology/business segmentCovers the main challenges facing the M2M industry today, and proposes early roll-out scenarios and potential optimization solutionsExamines the system level architecture and clearly defines the methodology and interfaces to be consideredIncludes important information presented in a logical manner essential for any engineer or business manager involved in the field of M2M and Internet of ThingsProvides a cross-over between vertical and horizontal M2M concepts and a possible evolution path between the twoWritten by experts involved at the cutting edge of M2M developments

Formal foundation and conceptual design of dynamic adaptations in a workflow management system

Abstract: While the different aspects of flexible workflow management are still under discussion, the ability to adapt the structure of running workflow instances to modified workflow schemas is an important property of a flexible workflow management system. In this paper, we present the formal foundation and conceptual design of dynamic adaptations in an object-oriented workflow management system. We describe in some detail how workflow schemas are represented. The system architecture, based on the CORBA object-oriented middleware, is overviewed, and the implementation of dynamic adaptations is sketched. An example introduces the graphical user interface of the system and shows a dynamic adaptation.

Synthesis of control circuits in folded pipelined DSP architectures

Abstract: A systematic folding transformation technique to fold any arbitrary signal processing algorithm data-flow graph to a hardware data-flow architecture, for a specified folding set and specified technology constraints, is presented. The folding set specifies the processor and the time partition at which the task is executed and is typically obtained by performing scheduling and resource allocation for the algorithm data-flow graph and the specified iteration period. The constraints imposed on the hardware architecture are also assumed to be known. The technique is used to derive the control circuitry of the hardware architecture. The authors derive conditions for the validity of a specified folding set, and present approaches to generate the dedicated architecture using systematic folding of tasks to operators. They propose automatic retiming and pipelining of algorithms described by data-flow graphs for folding. The folding algorithm is applied after preprocessing the data-flow graph for automated pipelining and retiming. >
