Workpackage 6 - Cognitive Spectrum Manager

The leader of WP6 is Klaus Moessner of UNIS.

The main challenges of this workpackage are:

• defining a dynamic spectrum portfolio management framework

• enabling coexistence of players (i.e., licensed and license-exempt users)

• providing methods to aggregate fragmented/scattered spectrum opportunities

• implementing spectrum etiquette and enforcement of policies



The main objectives of WP6 are:

  • Study and develop strategies, algorithms and metrics for the management of spectrum opportunities.
  • Build a framework for efficient spectrum management considering practical constraints and implementation limits regarding the characterization of spectrum and spectrum utilization strategies in the presence of QoS and mobility demands.
  • Consider mandatory security constraints by focussing on vulnerabilities of dynamic allocation and management of licensed and shared spectrum potentially compromising the license-exempt systems or the incumbent’s function and/or performance.
  • Provide solutions supporting dynamic spectrum allocation (including aggregation of fragmented or scattered spectrum)
  • to licensed users that request for `bandwidth on demand´ (e.g., incumbents), or that aim to extend their licensed services into white spaces (e.g., cellular operators);
  • to allow future licensed-exempt users (e.g., upcoming IEEE 802 systems) to efficiently utilize whitespaces in the presence of licensed primary users and other license-exempt users.
  • Investigate an integrated approach of dedicated cognitive functions potentially distributed across protocol layers and network entities enabling coexistence in conjunction with the optimization of spectrum usage across network diversity and spectrum fragmentation.
  • Propose useful test scenarios for the envisaged spectrum management framework to support work in WP7.


The envisaged spectrum management framework will consist of both centralized and distributed functions and modules addressing context (sensing and information sharing), signalling (distribution and collaboration/cooperation), security (protection of incumbents and license-exempt users), etiquette (policy management and enforcement), and adaptation (distributed and centralized self-X). The latter two partly complement and integrate with WP5 work and will provide additional spatio-temporal resource management (infrastructure) perspective to spectrum dynamics.
