—With the emergence of Web 2.0 and the related technologies, composing services has left the traditional frontiers of enterprises. In fact, end-users need to use a certain kind of composition in different situations since Web 2.0 has brought a set of technologies making it easy to create or collaborate on new services or use others' services, e.g., mashups.(More)
Service-oriented architecture (SOA) is realized by independent, standardized, and self-describing units known as services. This architecture has been widely used and verified for automatic, dynamic, and self-configuring distributed systems such as in building automation. This paper presents a building automation system adopting SOA paradigm with devices(More)
This paper explores the architecture and implementation details of SCOPE platform. SCOPE is our prototype for spontaneous P2P social networking. It provides customized social networking application for local use cases. Below the network level, SCOPE relies on 802.11 ad-hoc mode and needs no infrastructure. SCOPE follows the hierarchical P2P model. Some(More)
Mobile ad hoc network (MANET) can be the best option in developing seamless communication environment in various application scenarios where there is no any pre-defined infrastructure. A mobility model which represents movement behavior of considered application scenarios should incorporate important features that may change characteristics of mobile nodes.(More)
Facebook, the most popular Online social network is a virtual environment where users share information and are in contact with friends. Apart from many useful aspects, there is a large amount of personal and sensitive information publicly available that is accessible to external entities/users. In this paper we study the public exposure of Facebook profile(More)
The cluster between Internet of Things (IoT) and social networks (SNs) enables the connection of people to the ubiquitous computing universe. In this framework, the information coming from the environment is provided by the IoT, and the SN brings the glue to allow human-to-device interactions. This paper explores the novel paradigm for ubiquitous computing(More)
Wireless sensor networks (WSNs) have become pervasive and are used for a plethora of applications and services. They are usually deployed with specific applications and services; thereby precluding their re-use when other applications and services are contemplated. This can inevitably lead to the proliferation of redundant WSN deployments. Virtualization is(More)
WSNs have become pervasive and are used in many applications and services. Usually, deployments of WSNs are task-oriented and domain-specific, thereby precluding reuse when other applications and services are contemplated. This inevitably leads to the proliferation of redundant WSN deployments. Virtualization is a technology that can aid in tackling this(More)
