Pervasive computing is characterized by heterogeneous devices that usually have scarce resources requiring optimized usage. These devices may use different communication protocols which can be switched at runtime. As different communication protocols have different quality of service (QoS) properties, this motivates optimized self-adaption of protocols for devices, e.g., considering power consumption...
Nowadays, there is an increasing need for deploying Web services into embedded devices in pervasive computing environments. However, a number of problems arise for running pervasive web services, such as service not being accessible due to devices being located behind firewalls or NATs and therefore devices cannot offer services dynamically, and mobility problems as devices might change their location...
There is a growing trend to deploy Web services in pervasive computing environments. Implementing Web services on networked, embedded devices leads to a set of challenges, including productivity of development, efficiency of Web services, and handling of variability and dependencies of hardware and software platforms. To address these challenges, we developed a Web service compiler called Limbo, in...
Ontology is recognized as a key technology for the success of the semantic Web. Building reusable and evolve-able ontologies in order to cope with ontology evolution and requirement changes is increasingly important. But the existing methodologies and tools fail to support effective ontology reuse and evolution. In this paper, we present a product line based reuse-oriented ontology development methodology...
