Advanced planning strategies for wireless networks in a B3G reconfigurable radio context

Wireless communications migrate towards the "Beyond the 3(rd) Generation" (B3G) era. A fundamental concept for B3G is reconfigurability, which enables a true seamless mobility experience thanks to the dynamic adaptation, of network segments and terminals, to the set of Radio Access Technologies (RATs) that are most appropriate for handling the offered demand. Reconfigurability affects the way wireless infrastructures should be designed. This paper presents optimization functionality that can be used for the design of wireless infrastructures in a reconfigurable radio context. More specifically the paper aims at optimally assign the available RATs to reconfigurable transceivers, the service demand to RATs and the services to QoS levels (RAT, Demand and QoS-Assignment problem - RDQ-A). The RDQ-A problem is described and mathematically formulated. Finally, a greedy solution algorithm is proposed and results are presented.
