In order to facilitate the development and proliferation of multimedia services in ubiquitous environment, a context-aware multimedia middleware is indispensable. This chapter discusses the middleware support issues for context-aware multimedia services. The enabling technologies for the middleware such as representation model, context management, and multimedia processing are described in detail. On top of our previous work, the design and implementation of a context-aware multimedia middleware, called CMM, is presented. The infrastructure integrates both functions of context middleware and multimedia middleware. This chapter also aims to give an overview of underlying technologies so that researchers in ubiquitous multimedia domain can understand the key design issues of such a middleware.

<p>Computers are no match to humans in deducing situational information from their environment and in using it in their interactions. The advent of the context-aware applications seems to offer a way out to the computer that is not context-sensitive. The context aware applications can adapt their behaviors according to the perceived context or situation, without explicit user intervention, thereby providing human-centric services. To simplify the complexity of developing applications, context aware framework, which introduces context awareness into the environment where the applications are executed, is highlighted to provide a homogeneous interface involving generic context management and adaptation solutions. This papier has focused on the design of Context-Aware Health Services (CAHS) platform, which provide a health applications framework embedded on mobile devices. Our proposed platform is capabilities for context manager and adaptations according to context changes. It is designed to base on the SOA principles for achieving a flexible and dynamic architecture.</p>

Context Aware Service

Context-awareness is considered to be the cornerstone technique for developing pervasive computing applications that are flexible, adaptable, and capable of acting autonomously on behalf of the user. However, context-awareness introduces various software engineering challenges. The separation of concerns is a promising approach in the design of the context-aware adaptive processes (CAAPs) where the core logic is designed and implemented separately from the context handling and adaptation logics. In this respect, this chapter presents a conceptual framework for developing CAAPs and software infrastructure for efficient context management that together address the known software engineering challenges and facilitate the design and implementation tasks associated with such context-aware applications.

Common Strategy

The last decade has witnessed a steep growth in multimedia traffic due to real-time content delivery such as in online games and video conferencing. In some contexts, MANETs play a key role in the hyperconnectivity of everything in multimedia services. In this context, this work proposes a new scheduling approach based on context-aware mobile nodes for their connectivity. The contribution relies on reporting not only the locations of devices in the network but also their movement identified by sensors. In order to illustrate this approach, we have developed a novel agent-based simulator called MASEMUL for illustrating the proposed approach. The results show that a movement-aware scheduling strategy defined with the proposed approach has decreased the ratio of channel interruptions over another common strategy in mobile networks.
