in search of an internet of things Service Architecture rest or ws a developers perspective
International Conference on Mobile and Ubiquitous Systems: Networking and Services, 2011Co-Authors: Dominique Guinard, Simon MayerAbstract:Current trends inspired from the development of the Web 2.0 advocate designing smart things (e.g., wireless sensors nodes or home appliances) as Service platforms. Interoperable Services are mainly achieved using two different approaches: WS-* and RESTful Web Services. These approaches have previously been compared with respect to performance and features, but no work has been done to elicit the developers’ preferences and programming experiences. We conducted a study in which 69 novice developers learned both technologies and implemented mobile phone applications that retrieve sensor data, both through a RESTful and through a WS-* Service Architecture. The results complement the available technological decision framework when building Internet of Things applications. The results suggest that developers find REST easier to learn than WS-* and consider it more suitable for programming smart things. However, for applications with advanced security and Quality of Service requirements, WS-* Web Services are perceived to be better suited.

a peer to peer Service Architecture for the smart grid
International Conference on Peer-to-Peer Computing, 2014Co-Authors: Filipe Campos, Miguel Matos, Jose Pereira, David RuaAbstract:Important challenges in interoperability, reliability, and scalability need to be addressed before the Smart Grid vision can be fulfilled. The sheer scale of the electric grid and the criticality of the communication among its subsystems for proper management, demands a scalable and reliable communication framework able to work in an heterogeneous and dynamic environment. Moreover, the need to provide full interoperability between diverse current and future energy and non-energy systems, along with seamless discovery and configuration of a large variety of networked devices, ranging from the resource constrained sensing devices to servers in data centers, requires an implementation-agnostic Service Oriented Architecture. In this position paper we propose that this challenge can be addressed with a generic framework that reconciles the reliability and scalability of Peer-to-Peer systems, with the industrial standard interoperability of Web Services. We illustrate the flexibility of the proposed framework by showing how it can be used in two specific scenarios.

Knowledge-Based Service Architecture for Multi-risk Environmental Decision Support Applications
2011Co-Authors: Stuart Middleton, Zoheir SabeurAbstract:This paper describes our work to date on knowledge-based Service Architecture implementations for multi-risk environmental decision-support. The work described spans two research projects, SANY and TRIDEC, and covers application domains where very large, high report frequency real-time information sources must be processed in challenging timescales to support multi-risk decision support in evolving crises. We describe how OGC and W3C standards can be used to support semantic interoperability, and how context-ware information filtering can reduce the amount of processed data to manageable levels. We separate our data mining and data fusion processing into distinct pipelines, each supporting JDL inspired semantic levels of data processing. We conclude by outlining the challenges ahead and our vision for how knowledge-based Service Architectures can address these challenges.
