This will have an enormous impact on the way WSN applications are developed, deployed and maintained. Many applications for WSN are still developed on very low level functions provided by simple operating systems or bare hardware. Alternatively, generic WSN middleware focuses on very high-level system abstractions, such as declarative query languages, and acts as black box that tries to automatically map applications to the underlying resources.\u0000 In this paper, we propose scopes as a generic abstraction for the definition of groups of nodes. They bridge the gap between high- and low-level interfaces and enable the partitioning of WSN functionality. As middleware building block they facilitate the construction of tailored services in multipurpose WSNs.","PeriodicalId":364168,"journal":{"name":"workshop on Middleware for Pervasive and Ad-hoc Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125603562","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}

Characteristically, ubiquitous computing devices must blend into the background, unobtrusively collaborating to provide value-added services for users. Services are thus essential to the success of this technology and, as a result, both service discovery and service management will play a vital role in generating the revenue stream that is a prerequisite for sustainable ubiquitous deployment. On the one hand, the services provided should be evident by their richness and variety and on the other, the complexity inherent in the environment must be hidden from users. In this paper, we describe RUBI, a resource discovery framework for ubiquitous computing. RUBI represents a novel approach to resource discovery, because the primacy of the need for adaptive autonomic behaviour is established within its design.","PeriodicalId":364168,"journal":{"name":"workshop on Middleware for Pervasive and Ad-hoc Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133793272","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}

In order to meet the needs of applications, systems must adapt dynamically to changing situations. Since adaptation at one system layer may be insufficient, cross-layer, or <i>vertical</i> approaches to adaptation may be needed. Moreover, adaptation in distributed systems often requires <i>horizontal</i> co-operation among hosts. This cooperation is not restricted to the source and destination(s) of a data stream, but might also include intermediate hosts in an overlay network or mobile ad hoc network. We refer to this combined capability as <i>universal</i> adaptation. We contend that the model defining interaction between adaptive middleware and the operating system is critical to realizing universal adaptation. We explore this hypothesis by evaluating the <i>Kernel-Middleware eXchange (KMX)</i>, a specific model for cross-layer, cross-system adaptation. We present the KMX architecture and discuss its potential role in supporting universal adaptation in pervasive computing environments. We then describe a prototype implementation of KMX and show results of an experimental case study in which KMX is used to improve the quality of video streaming to mobile nodes in a hybrid wired-wireless network.","PeriodicalId":364168,"journal":{"name":"workshop on Middleware for Pervasive and Ad-hoc Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127087404","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}

Our experience shows that many of these building blocks fit neatly into one of five categories, each containing functionally-equivalent components. Effectively identifying the best-fit \"lego pieces\", which in turn determines the composite functionality of the resulting infrastructure, is critical. The selection process, however, is impeded by the lack of convention for labeling these classes of building blocks. The lack of clarity with respect to what ready-made subsystems are available within each class often results in naive re-implementations of ready-made components, monolithic and clumsy implementations, and implementations that impose non-standard interfaces onto the applications above. This paper explores each class of subsystems in light of the experience gained over two years of active development of both ubiquitous computing applications and software infrastructures for their deployment.","PeriodicalId":364168,"journal":{"name":"workshop on Middleware for Pervasive and Ad-hoc Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128938860","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}

Meanwhile, middleware systems have also been proposed in order to both facilitating the development of these applications and providing common application services. The development of middleware for sensor networks, however, places new challenges to middleware developers due to the low availability of resources and processing capacity of the sensor nodes. In this context, this paper presents a middleware for WSN named Mires. Mires incorporates characteristics of message-oriented middleware by allowing applications communicate in a publish/subscribe way. In order to illustrate the proposed middleware, we implement an aggregation middleware service for an environment-monitoring application.","PeriodicalId":364168,"journal":{"name":"workshop on Middleware for Pervasive and Ad-hoc Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134225303","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}

In particular, the synchronous communication paradigms often employed in standard middleware do not appear to be particularly suited to ad hoc environments, in which not even the intermittent availability of a backbone network can be assumed. Instead, asynchronous communication seems to be a generally more suitable paradigm for such environments. Message oriented middleware for traditional systems has been developed and used to provide an asynchronous paradigm of communication for distributed systems, and, recently, also for some specific mobile computing systems.\u0000 In this paper, we present our experience in designing, implementing and evaluating EMMA (Epidemic Messaging Middleware for Ad hoc networks), an adaptation of Java Message Service (JMS) for mobile ad hoc environments. We discuss in detail the design challenges and some possible solutions, showing a concrete example of the feasibility and suitability of the application of the asynchronous paradigm in this setting and outlining a research roadmap for the coming years.","PeriodicalId":364168,"journal":{"name":"workshop on Middleware for Pervasive and Ad-hoc Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124296281","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}

This task model contains information about the actions to undertake to help a user realize his daily tasks. The task model's mapping onto a deployment plan guides an internal adaptation mechanism, which helps applications to evolve without causing user distraction. In addition, a foraging technique (relocation) is proposed that allows for expanding an application's computing space automatically whenever possible. This technique involves external adaptation mechanisms. Both adaptation mechanisms are driven by resource information and resource contracts that are negotiated between the middleware and the application components. This allows the middleware to do the adaptations automatically, realizing the idea of calm computing.","PeriodicalId":364168,"journal":{"name":"workshop on Middleware for Pervasive and Ad-hoc Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117260059","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}
