Cloud computing often uses a multi-tenant architecture where tenants share application and system software. Request prioritization presents a challenge in this architecture. Tenant may have individual (local) prioritization requirements, and these requirements can be different for different tenants. The shared application must use a global priority scheme for requests from all the tenants. This paper...
Trust is an important problem in a community of interest (COI) built on top of service-oriented architecture (SOA). Furthermore, ranking services, data, and workflows in service-oriented applications is also important. This paper presents a role-based trust model to address these two problems. In this paper, users are classified into different roles in COI using role ontology (RO). The RO describes...
This paper presents a system for in situ atmospheric sensing using an aerial robot system in the presence of a strong wind field. The geostatistical concept of the variogram is used to characterize regions of the environment with high variability, which is assumed to correlate with scientific interest. After regions of interest are identified, ordered upwind methods are used to generate feasible trajectories...
This paper proposes dynamic and adaptive reliability methods that can be integrated into a collaborative composition framework with dynamic verification and adaptive reliability modeling. The composition process follows a template-based approach with ontology systems where a variety of items can be reused including services, workflows, application templates, and test cases/scripts. Items submitted...
Traditional service-oriented applications mainly focus on machine-to-machine interaction. However, human-machine interaction in applications also plays an important role. A better user interface can provide better usability and make the system user friendly. A user can be considered a service provider, where the user interaction is a workflow as a part of the system workflow and a user can place SOA...
