Hierarchical Brokering with feedback state observation in Mobile Device-Centric Clouds

We propose a Hierarchical Brokering Architecture (HiBA) and feedback control framework for Mobile Device-Centric Cloud (MDC2) computing. Exploiting RESTful Web-based interconnection, we probe availability and network latency as instant feedbacks needed by control and management in the hierarchical MDC2 federations. Future real-time seamless service and service-oriented federation are then achievable though distributed control and management algorithms. Performance model and experimental HiBA comprising heterogeneous devices and communication media both show that an MDC2 features better quality in terms of availability and network latency if it federates devices with enough resources distributed in lower tier hierarchy. Therefore, the proposed HiBA realizes a development platform for MDC2 computing which is a feasible solution to User-Centric Networks (UCNs).
