Wireless networks have gone through several years of evolution until now and will continue to do so in order to cater for the varying needs of users. These demands are expected to grow in the future, both in size and variability. Hence, the 5G technology considers these variabilities in service demands and potential data explosion which could accompany users' demands at the core of its architecture...
Mainly due to exponential growth in smart devices based mobile computing, the access networks are gaining tremendous momentum. Software defined networking (SDN), along with cloud computing and virtualization techniques, is considered as a major step forward from the conventional networking. Although SDN is being widely deployed in the data centers and enterprise networks, its adaptation in wireless...
We envision that in the near future, just as Infrastructure-as-a-Service, radios, and radio resources in a wireless network can also be provisioned as a service to mobile virtual network operators (MVNOs), which we refer to as Radio-as-a-Service (RaaS). A major obstacle for wide adoption of RaaS is the lack of incentives and fairness for allocating radio resources among MVNOs. In this paper, we present...
Wireless network virtualization is seen as a key component for future 5G networks. Virtualization enables flexible, ondemand, elastic network provisioning. We deem software defined networking (SDN) as a key enabling technology for virtualizing future wireless networks. In this regard, we introduce HetNet cloud, a software- defined cloud infrastructure for heterogeneous virtual wireless networks. As...
Undoubtedly, SDN has the potential to fundamentally change the way end-to-end networks are provisioned and designed. By introducing programmability into networking, the handling of network changes and network provisioning via open software interfaces has become a reality; together with the hardware/software virtualization advances in server systems and software platforms, cloud services can now be...
This paper proposes a next generation ubiquitous converged infrastructure to support Cloud and mobile Cloud computing services. The proposed infrastructure facilitates interconnection of fixed and mobile end users with IT resources through a heterogeneous network integrating optical metro and wireless access networks. To support the Infrastructure as a Service paradigm, the proposed architecture adopts...
