Design aspects for 5G architectures: The SESAME and COHERENT approach

The exponential growth of mobile data traffic still remains an important challenge for the mobile network operators. In response, the 5G scene needs to couple fast connectivity and optimized spectrum usage with cloud networking and high processing power, optimally combined in a converged environment. In this paper, we investigate two 5G research projects; SESAME [1] and COHERENT [2]. We consider the proposed 5G architectures and the corresponding key network components, in order to highlight the common aspects towards the 5G architecture design.
