“…We have investigated the requirements for building a software development framework that is useful for processing real-time computer-mediated social networks. Since the framework requires various services and software components to work coherently, a middleware design approach has been adopted, following the guidelines of Nakajima et al [12]. Our methodology is set to address the objectives presented in section 1.2.…”

An emerging research area in pervasive computing is the inference of social context in order to facilitate and mediate communications among collocated people. Understanding users' needs through information reasoning and leveraging principles of social networks plays an important role in the emergence of innovative computer-mediated social networks. This thesis introduces a generic social networking framework for the design, analysis and visualization of opportunistic social networks. The proposed framework is capable of analyzing social similarities in order to provide decision support to users in the form of ego-centric social graphs. Using opportunistic data networks, a distributed inference model is introduced to provide multi-criteria attribute matching in an ad hoc computing environment. Enhancing communications protocols to deal with real-time analysis of dynamic data, generation of spontaneous semantics, and introducing efficient social visualization techniques are salient goals of this research. Efficient pattern matching algorithms in mobile ad hoc networks can have significant benefits in generating real-time context and eliminate the need for a centralized arbiter. In our research, we demonstrate a generic and customizable software architecture for achieving efficient pattern matching in mobile ad hoc networks. In this research we present a novel design for the development of a generic matching engine that is customizable to changing social scenarios. We show how customizable semantics can play an important role in decision-making, selection of a desired attribute, and notifying users with messages in a volatile mobile network.

Abstract.A software platform for developing future information appliances requires to satisfy various diverse requirements. The operating system architecture presented in this paper enhances the flexibility and dependability through virtualization techniques. The architecture allows a system to use multiple operating systems simultaneously, and to use multi-core processors in a flexible way. Also, dependability mechanisms in our architecture will avoid crashing or hanging a system as much as possible in order to improve the user experience when defects in the software are exposed. We present a brief overview of each component in the operating system architecture and some sample scenarios that illustrate the effectiveness of the architecture.

“…We believe that the appropriate world model is very important to develop contextaware services that are natural to users. The final topic is to collect experience with building middleware infrastructures for ubiquitous computing [5,6]. We especially believe that it is important to consider the effect of human factors in the design of middleware infrastructures.…”

Our daily life will be more attractive when our surroundings will be more intelligent. Most of current researches in ubiquitous computing try to build a smart environment by embedding sensors and computers in our living spaces directly. However, the approach is very expensive to make our environment smart. Our approach uses intelligent daily objects and personal devices to build a smart environment. This makes it possible to make our environment smart in an incremental way by replacing existing objects to new intelligent objects whenever a person wants. In our project, we are currently developing sentient artefacts that are intelligent daily objects embedding computers and sensors. Also, we are implementing middleware infrastructures for personal devices that allow us to control embedded services in an easy way.
