A Platform for Context-Aware Application Development: PCAD

Abstract

Abstract-We propose a novel software platform based on the notion of context-awareness which allows rapid and easy development of context aware applications. One of the fundamental goals of the proposed platform is extensibility, allowing the platform to react to new requirements without making fundamental and substantial changes. The Context Aware Application Development Platform-PCAD-has inspired from an operating system and modeled as a layered architecture. It exhibits a plug-and-play behavior very similar to devices and device drivers found on an operating system/kernel. The platform offers functions such as data management, notification, security and privacy as services. The platform provides a public interface to application developers in their development of context-aware applications. It covers a wide range of disparate application domains such as smart city and livestock monitoring applications.

Application of Service-Oriented Context-Aware Architecture to Laundry Management System

“…Truong et al studied contextaware web service [24] and Miraoui et al [15] surveyed pervasive context-aware architectures. Celikkan and Kurtel [6] and Merezeanu et al [14] proposed platforms which separate context data retrieval and storage from the business logic. The PCAD platform [6] by Celikkan and Kurtel presents platform architecture for context aware application development, enabling context aware applications to be built rapidly using services provided by the platform.…”

The PCAD platform [6] by Celikkan and Kurtel presents platform architecture for context aware application development, enabling context aware applications to be built rapidly using services provided by the platform. The platform manages the common work such as context acquisition and storage, therefore enabling the application to focus on the domain specific logic.…”

“…In addition to obtaining data from sensors directly, this layer is able to retrieve and aggregate context data from external sources through the virtual sensor abstraction using, for example, web services, and store it in its database. As an example, the external context aware application development platform PCAD [6] provides an interface to make its context data available to those requesting it.…”

“…Some common interfaces used to exchange data are Web services and XML. PCAD [6] provides an API via a library, and an HTTP request-response mechanism to provide interoperability with other systems.…”

Context-aware Control Platform for Sensor Network Integration in IoT and Cloud

“…Celikkan and Kurtel [4] propose a context-awareness based software platform modeled as a layered architecture, having extensibility as main facility. Boddhu et al analyse the integration of Human-centric sensing paradigm in a generic architecture able to enhance situational awareness [2].…”
