    Fixed multiplexed access radio networks can realize collision-free transmission while suffering low flexibility, especially in ad hoc communication. This paper demonstrates that a dynamic spectrum access based cooperative relay technology, defined as cognitive relay, contributes toward improving the flexibility of fixed radio networks to bursty heavy traffic, unbalanced traffic loads and terminal mobility.
