Technology (RAT) selection algorithm, including initial RAT selection and vertical handover,
is one of the key research areas in Common Radio Resource Management (CRRM). A
suitable RAT selection algorithm can maximize the system performance and Quality of
Service (QoS) by allocating users to the most suitable RAT in the case of two or more RATs
co-located in the same coverage area. This paper evaluates the performance of three RAT …
