Research on sensor network has been focused at overcoming these deficiencies through more energy efficient routing, localization algorithms and system design. This paper tried to discuss some application related challenges, such as data integration, data storage, metadata generation, data fast query. We use analytical data management concept to create a virtual layer, which maps the real sensor network...
Exceptions cause temporal failures of Web-based systems to deliver continuous and responsive end-to-end services. On cloud platforms, resource provisioning and administration become less explicit, which entails techniques that can act on exceptions according to known strategies. In this paper, we propose a middleware-based approach that encompasses a healing process that links available strategies...
Quality of individual services is substantial to guarantee high performance and availability of overall composite service oriented systems. This requires the process of diagnosing service quality degradation and responding to it in a timely and non-stopping manner. This paper presents a modeling-based approach to coordinate the process of Web service management, configuring parameters or invoking...
