Abstract: In this paper we present algorithms for dynamic channel allocation with QoS support. In particular, we focus on the integration of networks with different Radio Access Technologies (RATs), as is currently subject of investigation within the novel concept of Ambient Networks. On this matter, we investigate the introduction of collaborative channel assignment, which exploits service elasticity and the tunability offered by QoS management. To this end, the comparison between non cooperative and cooperative resource allocation is briefly discussed and simulations are performed to demonstrate how collaborative strategies are able to improve system performance.
