Mapping of Secondary Virtual Networks onto Wireless Substrate based on Cognitive Radio: multi-objective formulation and analysis
There is a growing demand for wireless services with different requirements in a dense and heterogeneous wireless environment. Handling this complex ecosystem is becoming a challenging issue, and wireless virtualization emerges as an efficient solution. Although the inclusion of virtualization in wireless networks ensures a better use of resources, current approaches adopted for wireless virtua...
متن کاملEfficient Mapping of Virtual Networks onto a Shared Substrate
Virtualization has been proposed as a vehicle for overcoming the growing problem of internet ossification [1]. This paper studies the problem of mapping diverse virtual networks onto a common physical substrate. In particular, we develop a method for mapping a virtual network onto a substrate network in a cost-efficient way, while allocating sufficient capacity to virtual network links to ensur...

متن کاملAdaptive relaying scheme for cognitive radio networks
Cognitive radio (CR) systems allow unlicensed secondary users to transmit on the licensed frequency bands without degrading the licensed primary transmissions. Combining CR with other emerging transmission techniques, such as user cooperation may have many benefits on both the primary and secondary transmissions. In this study, the authors propose and investigate an adaptive relay-based coopera...
متن کاملOptimization of Secondary User Capacity in Dual Threshold Scheme in Cognitive Radio Using Evolutionary Algorithm
AbstractIn cognitive radio network, through efficient spectrum utilization the secondary user (SU) capacity maximization is an important work, here we optimize the secondary user capacity through threshold in the dual threshold scheme of cooperative spectrum sensing by taking the primary user( PU ) on priority as well as SU on priority in AWGN and Rician channel with the evolutionary optimizati...
