Multiaccess Radio Network Enviroments

Nowadays there is a plethora of independent radio access technologies (RATs), each supporting distinct coverage, mobility, data rates, and quality of service (QoS). The cornerstone of all visions on future wireless networks is that there will be a multiaccess network environment, where users will be able to select from various available multiple heterogeneous access networks the most appropriate one to satisfy specific application requirements. On the other hand, emerging applications call for the vehicular networks to support multimedia and real-time services.
