A Novel Synergy Selection Mechanism among Multi- Devices for Ubiquitous Services

It is a challenge to select an optimal set of devices to accomplish a graph-based ubiquitous service and execute it continuously under the circumstances of dynamic environments and limited device capability. We elaborate a Synergy- aware Selection Mechanism （SSM） considering synergetic among devices. In the SSM, we design a distributed algorithm to integrate the devices and a dynamic updating weight method. The simulation results show that SSM can make devices composed together to ensure the continuity and smoothness of service

Assessing Level of Ubiquitous Computing Services for Ubiquitous Business Design

We are entering into a new era of enterprise computing that is characterized by an emphasis on broadband convergence, knowledge sharing, and calm services. Some people refer to this as the 'ubiquitous network' business model because its focus is on a high degree of connectivity between a company and its customers, suppliers, and channel partners. Moreover, immediate access to ideas, goods, and services will be of greater value than the traditional model of permanent and ponderous possession. This paper illustrates how ubiquitous computing technology can be combined with legacy computer-based information systems, along with thoughts on relevant issues of ubiquitous commerce. We also propose a model for how to assess levels of ubiquitous computing services.

Automatic generation of context-aware workflow documents for ubiquitous robot services

Intelligent robots in ubiquitous computing environment should be able to receive a variety of surrounding informa tion and provide users with appropriate services. A developer can describe the robot services that are proper to users＇ envir onments by using his or her various environments, and process them through the execution engine. However, it is difficult for a developer to describe and develop robot services, who knows all surrounding information which is called context infor mation. If there is a method for describing and documenting robot services in intuitive expressions, that is to use graphical user interfaces（GUls）, it would be very helpful. This paper suggests that robot service developers describe robot services us ing intuitive GUls with contextawareness. And the services can be automatically generated into workflow documents. Robot services that robot service developers have made with intuitive GUIs can be automatically generated into workflow docu ments by using the object modeling technique（OMT）. Developers can describe robot services based on contextaware work flow language（CAWL ）. For testing, scenariobased robot services are described using CAWLbased development tool, and their workflow documents are automatically generated.

A Study on Smart Home Design Incorporating Ubiquitous Healthcare Services

The smart home using ubiquitous technology can effectively provide services to the elderly and the physically impaired. However, such services are accompanied by high initial cost of installation and the operating inefficiency due to the absence of design guidelines. To solve these, the integrated management of the process by supplying the public service like voucher schemes to the dwelling is needed. This paper mainly proposes a research about the healthcare service in a residential environment, which includes medical service and safety service and so on, by surveying the voucher program and the in-house infra status. Finally, the house planning elements for healthcare-based smart home are drawn and the planning directions through expert survey are suggested. Therefore, this study surveyed on voucher program and in-house infra status, and drew the house planning elements for health-based care smart home. In addition, this study suggested the planning direction through expert survey. This study can be used as a guideline for constructing a smart home, which supplies healthcare service.

Multiple Mobile Sinks Data Dissemination Mechanism for Large Scale Wireless Sensor Network

WSN has been developing from traditional environment monitoring applications to the ubiquitous information services such as the Congestion-oriented Intelligent Transportation System （ColTS）. However, the mobility of nodes makes data dissemination a hard nut to crack. In this paper, we propose MSDD, a multiple mobile sinks data dissemination mechanism for solving the dissemination problem. The main ideas of MSDD are constructing a two-tier grid structure by a designated sink, exploiting a hierarchical monitoring mechanism, and employing a global agent to track the sink locations in order to make the emergencies reported to the sinks immediately, In addition, MSDD supports the query-driven data dissemination. Being compared with TTDD, MSDD is theoretically proved to have less communication overhead. We also validate MSDD outperforms TTDD in reliability and the emergency delivery latency bv simulations.

Ubiquitous information service networks and technology based on the convergence of communications, computing and control

The rapid development of the IoT(Internet of Things)is bringing about a functional change of communication networks from“information transmission”to“information service”.First,the conception and characteristics of the IoT are in-troduced,i.e.,an Internet of humans,machines,and things meant to achieve smart information services.Then,the technology requirements for realizing ubiquitous and smart information services are described.The corresponding key technologies are also discussed,including the integration of communications,computing and control technology(3C),heterogeneous network fusion theory and technology,intelligent sensor technology and short-distance networking theory,large-scale network transmission theory and technology,the network virtualization and intelligent computing technology geared toward information service,and the collaborative network system and service model geared to the application of the IoT.Finally,the development trends of in-formation technologies and information networks in the next five to ten years are analyzed,and give some suggestions for main research areas to be explored and key issues to be resolved.
