Jamming Impact on Wireless Resource Allocation in Wireless Virtualization

Jamming attacks can significantly affect the overall performance of the wireless communication systems as jammers aim to deteriorate the signal quality at the receiver or jam the communication channels to block legitimate communications. Jamming attack is common in wireless virtualization since wireless resources are subleased from primary wireless resource owners (PWROs) to mobile virtual network operators (MMVOs) based on their service level agreements (SLA). MMVOs provides wireless services to the end users and meet their data rate requirements. Wireless network suffer from multitude of attacks including eavesdropping and jamming. Jamming attacks are launched to jam the channels or deteriorate the received signal quality at the targeted receivers. When there is a jamming attack in wireless virtualization, the MMVOs will have to sublease more wireless resources from PWROs to meet their users’ data rate requirements to compensate the impact of the jamming attack in user data rates. Specifically, to combat jamming impact, legitimate transmitter (MVNOs’ virtual base stations which are created by using subleased based stations and wireless RF slices of PWROs) will have to use high power, use channel hopping strategy or use wide-bands to meet the data rate requirements. This paper studies the jamming impact on wireless resource allocation (power and bandwidth) in wireless network virtualization. Specifically, we show how much extra power and/or bandwidth is needed to combat a given jamming impact while meeting the data rate requirements of the users. Performance evaluation is done using numerical results obtained from simulations.
