Resource Trust Management in Auto-Adaptive Overlay Network for Mobile Cloud Computing

Management of large distributed servers and mobile devices as resources that define Mobile Cloud systems is a complex problem of critical importance in our days when large number of users with high-heterogeneous mobile devices interacts in various ways. Efficient management of heterogeneous resources requires uniform overlay network with well-established joining and routing protocols. An auto-adaptive overlay is a fault tolerant one, creating a reliable system. When network resources are unreliable and sometime untrusted, trust management becomes an important issue for resource selection and allocation. This paper describes a new model for resource trust management in Mobile Cloud systems. It uses a bio-inspired structure for constructing the overlay in a honeycomb structure. Then we introduce a model for resource trust management based on feedback, which is very similar to peer-to-peer trust management systems like Eigen Trust, R2Trust, Super Trust or Trust Me. Based on overlay construction and trust value computation, we propose a general flow for a resource request in Mobile Cloud systems logically organized as a honeycomb structure. We evaluate the proposed solution using simulation and the obtained results highlights the performance of proposed auto-adaptive overlay that can be use as a content distribution platform in Mobile Cloud systems.
