The objective of the AROMA project is to devise and assess a set of specific resource management strategies and algorithms for both the access and core network parts of an all-IP heteroge-neous wireless access network that guarantee the end-to-edge quality of service. The complexity of the interaction between Be-yond 3G systems and user applications, while dealing with the quality of service concept, motivates the development of this kind of emulation platforms, where algorithms and applications can be tested in realistic conditions that could not be achieved by means of off-line simulations.
