Context-Aware Services Provisioning on Top of Active Technologies

Abstract. With respect to the pervasive computing vision, the paper deals with the efficient provisioning of context-aware services making use of Active Networks (ANs) on top of fixed and mobile infrastructure. This represents a starting point for studying on the utilization of Active Technologies in order to provide context-aware services. In these terms, Mobile Agent (MA) Technology comprises a type of Active Technology and the exploitation of its utilization in the field of context-awareness is analyzed. Following, an evaluation comparison of ANs and MAs paradigms is given, identifying the drawbacks and the advantages of each paradigm. Finally, some concluding remarks regarding the combined usage of them are presented.

Security-enabled code deployment for heterogeneous networks

Future services on converged heterogeneous networks are expected to increase the demand for code distribution on fly installment and dynamic management. Component discovery, download, installation, revocation, and profiling are critical in supporting next-generation enabling technologies and application evolvement. We present here the architecture of an active component manager and discuss metadata that should be used to describe components and their capabilities. Furthermore, we elaborate on XML digital signatures as an integral part of secure component distribution. Finally we investigate topologies for component distribution and how emerging technologies like peer-to-peer could be used in the context of active component manager. This paper is motivated by the vision of Google-like code discovery, and flexible management of it, within the future semantic web context
