Abstract:
The rapid growth of the mobile devices and its services being experienced in a recent years brought both
challenges and opportunities in the wireless network systems. The scarcity of the resources, high capital and
operational costs are among the challenges facing the provision of the growing mobile services. The development of
wireless network virtualization brought hope for the future networks to fulfil the users’ demands. It allows different
service providers to share the same physical infrastructure which in return, reduces both capital expenses (CAPEX) and
operational expenses (OPEX). In this paper, the framework for wireless network virtualization is proposed. Also, the
detailed description of the model based on the software define network (SDN) architecture is presented. On top of that
we have proposed a load based resources sharing approach among the virtual networks (VNs). Our proposed approach
has shown that, through sharing the excess resources, the VNs can significantly minimize unnecessary cost and utilize
the available resources effectively.
