Abstract

This chapter discusses the cognitive radio policy language (PL) and policy engine (PE). Various design considerations apply to any PL and PE for CRs and DSA. Different choices lead to different expressiveness of language and varying reasoning capabilities. It provides an overview of the requirements for the PL and PE that inform design. There are many advantages in using a policy-based approach to CRs. Deployment delays are drastically reduced because a policy-based architecture enables policies, policy reasoners, and radio devices to be accredited separately. Policies can be used to describe preferences and constraints on parameters, such as priority of traffic, security, quality of service, and probability of interference. Radio behavior can be changed in flexible ways at runtime by changing such policies. Finally, by having policies with clear, easily understood semantics, one can coordinate a variety of organizational entities. For example, regulators can specify admissible transmission behavior in a policy, or network managers with proper authority can activate, or deactivate, policies to flexibly control the network.
