1. What are the contributions mentioned in the paper "Wiback: a sdn enabled wireless back-haul network architecture for future 5g networks" ?
This will lead to not only modifications in the access segment and parts of core networks, but will trigger changes throughout the whole network, including the Back-haul segment.. In this work the authors present their vision of a 5G Back-haul network and identify the associated challenges.. The authors then describe their Wireless Back-haul ( WiBACK ) architecture, which implements Software Defined Network ( SDN ) concepts and further extends them into the wireless domain.. Finally the authors present a brief overview of their evaluation results.

2. What are the future works in "Wiback: a sdn enabled wireless back-haul network architecture for future 5g networks" ?
The authors have presented their vision of future Back-haul networks in a 5G environment and the challenges that need to be solved in order to cope with requirements of future services and their associated traffic volumes and pattern.. The authors acknowledge that future networks need to be highly flexible and, thus, should follow the SDN concepts and extend them even further to also control ( wireless ) interfaces to become a SDWN.. Furthermore, the authors have presented their WiBACK architecture, and have shown that it can already be seen as a SDWN implementation for wireless Back-haul networks.. Fture work will focus on a close integration with the EPC and other potential applications for their SDWN controller.
