SmartShadow: Models and Methods for Pervasive Computing by Zhaohui Wu, Gang Pan

By Zhaohui Wu, Gang Pan

SmartShadow: types and techniques for Pervasive Computing deals a brand new standpoint on pervasive computing with SmartShadow, that's designed to version a person as a character “shadow” and to version pervasive computing environments as user-centric dynamic digital own areas. similar to people’ shadows within the actual global, it follows humans anyplace they pass, supplying them with pervasive prone. The version, tools, and software program infrastructure for SmartShadow are awarded and an software for shrewdpermanent autos is usually brought.

The booklet can function a priceless reference paintings for researchers and graduate scholars within the box of pervasive/ubiquitous computing.

Zhaohui Wu is a Professor at Zhejiang college, Hangzhou, China. Gang Pan is a Professor on the comparable institute.

Theoretical Aspects of Evolutionary Computing

In the course of the first week of September 1999, the second one EvoNet summer time college on Theoretical elements of Evolutionary Computing was once held on the Middelheim cam­ pus of the college of Antwerp, Belgium. initially meant as a small get­ jointly of PhD scholars attracted to the idea of evolutionary computing, the summer season college became a winning mixture of a four-day workshop with over twenty researchers within the box and a two-day lecture sequence open to a much wider viewers.

Sample text

20 1 SmartShadow Model on the person ontology of SOUPA, which specifies a personal profile of a user, including identity, name, location, gender, education, and intentions. The user description also specifies a comfortable interaction zone. Only within this range is a user comfortable with the moving distance to interact with some services/devices. 6 Planning for a Virtual Service Space: ServiceShadow Once the intentions of a user and the services in the environment are known, a virtual service space can be constructed with service discovery, matching, and composition by a planning algorithm.

The Gaia OS is provided as system software infrastructure to implement mobility. Gaia’s scheme is a tight coupling solution for mobility, which cannot cope with openness and heterogeneity of smart environments. Preuveneers and Berbers [7] use the OSGi platform to implement the smart service’s synchronization. They mainly focus on service diffusion and how to redeploy the same service on other hosts in a synchronous service state. The approach cannot deal with high-level task migration across heterogeneous devices since it has no semantic abstraction of tasks and environments.

2) Nontrigger state node: It refers to the node that does not require system response, called critical state node. 48 3 Context-Awareness in SmartShadow Fig. 3. The model allows three types of state transition between context situations: (1) Nontrigger state → trigger state: This transition represents a change from critical state to crisis state, which means a service will be triggered.
