End-to-End Architecture for Adaptive Communication Systems

Reconfigurability is considered the collection of software and cognitive radio technologies that aim to differentiate user perception in volatile radio conditions while optimizing the use of network resources. The realization of equipment reconfiguration through software download and the efficient utilisation of spectrum require coordinated distribution of functionality among the user, control, and management planes. This contribution presents the end-to-end architecture of future adaptive communication systems based on the Reconfiguration Management Plane model, which includes intelligence for policy-based context-aware decision making, negotiation control, software download, and dynamic spectrum management. The paper presents the RMP functional model, describes the dependencies and associations of the constituent context management module, and delineates the end-to-end quality of service negotiation information flow when introducing dynamic spectrum access in user-to-user communication scenarios.
