Abstract: The use of Network Function Virtualization (NFV) and Software Defined Network (SDN) provides opportunities to offer services with lower CAPEX/OPEX for service providers and deploy new services quickly. However, it will introduce new challenges. One of the main challenges is an optimized placement of the virtualized functions based on the characteristics and available resources of the network. Placement of Network Functions (NFs) can affect the path traffic flows take and consequently bandwidth usage in the network. While most of the research is focused on the challenges of NFV in wired networks, it can also be applied to wireless networks. However, the specific differences between the wired and wireless networks should be considered. In this paper, we are expanding one of the comprehensive placement methods in the wired networks which use Integer Linear Programming (ILP) to place a chain of NFs. The extended model formulates the main characteristic of the wireless networks which is a scarcity of bandwidth due to interference. As our results show, the interference in the wireless networks increases the bandwidth usage and consequently the average NF deployment cost. To address this, we can either increase the number of nodes or the nodal resources to achieve higher placement success rates. (More)
