2. 1. Agile, Resilient and Cost-efficient Mobile Backhaul Networks

   Author : Forough Yaghoubi; Lena Wosinska; Marija Furdek; Jiajia Chen; Amitava Mukherjee; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; software defined networking; rain disturbance; technoeconomic framework; network consistency.; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : The exponentially increasing traffic demand for mobile services requires innovative solutions in both access and backhaul segments of 5th generation (5G) mobile networks. Although, heterogeneous networks (HetNets) are a promising solution for the wireless access, the backhaul segment has received considerably less attention and falls short in meeting the stringent requirements of 5G in terms of capacity and availability.
