It makes quite difficult to detect manually critical or relevant situations that may occur in marine traffic. In this paper, we propose an event-driven service-oriented-architecture that combines the complex event processing and data distribution system, building a high performance and available system for analyzing and correlating data provided by ship's automatic identification systems in real time. This architecture will be able to detect automatically, and as soon as possible, abnormal situations occurred in seas all over the world. For this, a set of complex event patterns for detecting AIS hijacking or failure, as well as ship engine malfunction or ship collision is proposed and defined in this work.","PeriodicalId":139932,"journal":{"name":"WAS4FI-Mashups '12","volume":"225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115233948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Future service-oriented Internet things will offer their functionality via service-enabled interfaces. The new emergent OASIS standard DPWS has been designed as a set of guidelines based on WS-* specifications to provide interoperability among heterogeneous things in a networked environment. But there is still a need to represent explicitly the (implicit) behaviour of things in order to develop applications in a more rigorous way. In this paper, we promote the usage of WS-* specifications to specify service interfaces of things by adding a set of constraints to the guidelines exposed by DPWS to represent the behaviour of single and composite things by reducing inconsistency problems, such as deadlock situations. We also point out some brushstrokes of our future work, first proposing verification techniques to check if a composition of things fulfills or violates the behaviour of the things, second leading to a platform to support the development of behaviour-aware compositions of things, and third extending the approach to consider important aspects in compositions such as semantic, context and social information.","PeriodicalId":139932,"journal":{"name":"WAS4FI-Mashups '12","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126102183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensors that make part of these long-lived networks have to be reconfigured according to context changes in order to preserve the operation of the network. Such reconfigurations require to consider the distributed nature of the sensor nodes as well as their resource scarceness. Therefore, self-adaptations for WSNs have special requirements comparing with traditional information systems. In particular, the reconfiguration of the WSN requires a trade-off between critical dimensions for this kind of networks and devices, such as resource consumption or reconfiguration cost. Thus, in this paper, we propose to exploit Constraint-Satisfaction Problem (CSP) techniques in order to find a suitable configuration for self-adapting WSNs, modelled using a Dynamic Software Product Line (DSPL), when the context changes. We exploit CSP modeling to find a compromise between contradictory dimensions. To illustrate our approach, we use an Intelligent Transportation System scenario. This case study enables us to show the advantages of obtaining suitable and optimized configurations for self-adapting WSNs.","PeriodicalId":139932,"journal":{"name":"WAS4FI-Mashups '12","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127552451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mashup composition tools are at the core of this paradigm attracting increasing attentions from both academic research and industry. The ever increasing number of mashup tools bespeaks an urgent need for a comprehensive evaluation and comparison mechanism. This is needed not just because it helps identify the strengths and weaknesses of a mashup tool against the others, but also because it can guide future research and development efforts. To address this need, benchmarking is a promising approach providing a strong evaluation mechanism based on quantitative and reproducible measurements.

The EUD community has gathered a wealth of expertise in creating socio-technical systems and user-centric software design environments in pursuit of this aim. Some of this expertise is highly relevant to the creation of software mashups, especially when the latter are oriented towards non-programmers. To facilitate the exchange of ideas between these two areas, we have initiated the development of an analytical framework bridging the perspectives of service-based software development and EUD. The framework aims to serve as a tool to analyze efforts aiming to open up mashups to non-programmers, and to compare them along different dimensions, highlighting sectors which require further input and development. In this position paper we present the first iteration of developing the framework, focusing on two dimensions of a table -- EUD and Service-Oriented Development. The different stages and activities of the Service-Oriented Development provide the different rows of the table. The columns are formed by five aspects of End User Development which we find particularly relevant in this context. To demonstrate the framework in action, we report on a classification exercise which took place during the second workshop on End User Development for Services in 2011 (see www.eud4services.org).","PeriodicalId":139932,"journal":{"name":"WAS4FI-Mashups '12","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131910981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the use and development of cloud services has not been standardized, thereby deriving in migratability and interoperability difficulties. Different standardization initiatives exist seeking to normalize this situation, however none has predominated and a generalized consensus has not been reached. Consequently, several alternatives have been proposed based on the use of intermediate layers or middlewares seeking to isolate developers from the variability of specific cloud vendor services. These approaches provide a valid solution at the risk of shifting the lock-in effect from vendors to middlewares. In this paper, we explore an alternative solution based on the use of software adaptation (SA) techniques. Different guidelines are presented as the basis of an approach that will favor cloud application interoperability and migratability thereby avoiding vendor lock-in.","PeriodicalId":139932,"journal":{"name":"WAS4FI-Mashups '12","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124493802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
