Building a platform-agnostic wireless network of interconnected smart objects

In this work, we present a platform-agnostic framework for integrating heterogeneous Smart Objects in the Web of Things. Our framework, consists of 4 different hardware platforms, Arduino, SunSPOT, TelosB, iSense. These hardware platforms are the most representative ones, as used by the relevant research community. A first contribution of our work is a careful description of the necessary steps to make such a heterogeneous network interoperate and the implementation of a network stack, in the form of a software library, named mkSense, which enables their intercommunication. Moreover, we describe the design and implementation of software library which can be used for building "intelligent software" for the Web of Things. © 2011 IEEE

A web services-oriented architecture for integrating small programmable objects in the web of things

In this work, we present a concrete framework, based on web services-oriented architecture, for integrating small programmable objects in the web of things. Functionality and data gathered by the Small Programmable Objects (SPO) are exposed using Web Services. Based on this, by exploiting XML encoding, SPO can be comprehensible by any web application. The architecture proposed is focused in providing secure and efficient interoperability between SPO and the web. Additionally, the proposed architecture provides management capabilities for deploying, maintaining and operating SPO applications across multiple networks. We present the multilayer architecture of our system and its implementation, which uses a combination of Java Standard and Micro Editions. Finally, we present a case study presenting our implementation. In this application we use SunSPOTs, which are wireless network motes developed by Sun Microsystems. © 2010 IEEE

Brief announcement: Fun in numbers - A platform for sensor-based multiplayer pervasive games

We examine multi-player pervasive games that rely on the use of ad-hoc mobile sensor networks. The unique feature in such games is that players interact with each other and their surrounding environment by using movement and presence as a means of performing game-related actions, utilizing sensor devices. We briefly discuss the fundamental issues and challenges related to these type of games and the scenarios associated with them. We have also developed a frame- work, called Fun in Numbers (FinN) that handles a number of these issues, such as such as neighbors discovery, localization, synchronization and delay-tolerant communication. FinN is developed using Java and is based on a multilayer architecture, which provides developers with a set of templates and services for building and operating new games

Implementing multiplayer pervasive installations based on mobile sensing devices: Field experience and user evaluation from a public showcase

In this work we discuss Fun in Numbers, a software platform for implementing multiplayer games and interactive installations, that are based on the use of ad hoc mobile sensing devices. We utilize a detailed log of a three-day long public showcase as a basis to discuss the implementation issues related to a set of games and installations, which are examples of this unique category of applications, utilizing a blend of technologies. We discuss their fundamental concepts and features, also arguing that they have many aspects and potential uses. The architecture of the platform and implementation details are highlighted in this work, along with detailed descriptions of the protocols used. Our experiments shed light on a number of key issues, such as network scaling and real-time performance, and we provide experiments regarding cross-layer software issues. We additionally provide data showing that such games and installations can be efficiently supported by our platform, with as many as 50 concurrent players in the same physical space. These results are backed up by a user evaluation study from a large sample of 136 visitors, which shows that such applications can be seriously fun. © 2011 Elsevier Inc. All rights reserved

Using wireless sensor networks to develop pervasive multi-player games

In this work we present two mobile, locative and collaborative distributed games that are played using wireless sensor devices. We briefly present the architecture of the two games and demonstrate their capabilities. The key characteristic of these games is that players interact with each other and their surrounding environment by moving, running and gesturing as a means to perform game related actions, using sensor devices. We demonstrate our system's implementation, which uses a combination of JAVA Standard and Mobile editions. © 2008 ACM
