Core and Spectrum Allocation for Avoidance of Spectrum Fragmentation in EON-SDM
ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020In Elastic Optical Networks with Space-Division Multiplexing (EON-SDM), dynamic allocation and deallocation of the spectrum can cause spectrum fragmentation. A possible solution is the use of proactive techniques to reduce the occurrence of fragmentation. In this paper, we propose a proactive algorithm for EON-SDM networks using Multi-Core Fibers (MCFs)

Routing and Spectrum Allocation
2016To properly analyze, design, plan, and operate flex-grid networks, the routing and spectrum allocation (RSA) problem must be considered. The RSA problem involves two basic constraints: the continuity constraint to ensure that the allocated spectral resources are the same along the links in the route, and the contiguity constraint to guarantee that ...

Allocating spectrum: Towards a commons future
2012 IEEE International Symposium on Dynamic Spectrum Access Networks, 2012Spectrum divide is a consequence of the current spectrum management framework which is locked into a paradigm that is based on assigning spectrum exclusively to a number of operators. This regulatory gridlock is due to resistance from current institutional framework, decision making political economy, and misconception of commons.

Spectrum Allocation and the Internet
2002The Internet is transforming communications around the world, even with the downturn in the technology market that we saw at the start of this century. This transformation permeates all forms of communications, but its success at realizing maximum consumer benefits depends, at least in part, on the flexibility of communications regulation.

Ensuring Minimum Spectrum Requirement in Matching-Based Spectrum Allocation
IEEE Transactions on Mobile Computing, 2018To enable dynamic spectrum access, service providers with spare spectrum (sellers) trade with those who are in need of additional spectrum (buyers). In a spectrum market, the transaction result is essentially a matching between sellers and buyers. Though it is tempting to optimize the matching over certain utility functions, a stable matching is more ...

Spectrum aggregation based spectrum allocation for cognitive radio networks
2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014In cognitive radio networks, the available spectrum holes are usually discontinuous. Hence, it is hard to exploit these spectrum holes because the bandwidth of an individual one may not be able to satisfy the wide bandwidth requirement imposed by secondary users (SUs).

Joint Dynamics of Spectrum Allocation and User Behavior in Spectrum Markets
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009Adaptive radio resource management policy aware of the demand for wireless services is termed dynamic spectrum access (DSA). In order to evaluate the effectiveness of DSA, dynamics of the demand should be considered. In the present paper, dynamics of the spectrum market, which is a way to realize DSA, are evaluated from the economic perspective ...

Spectrum allocation and scheduling in dynamic spectrum access wireless networks
The Fourth International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness & Workshops, 2007In this paper, we study the joint spectrum allocation and scheduling problems with the objectives of maximizing through-put and achieving certain fairness in Dynamic Spectrum Access (DSA) wireless networks. A novel Multi-Channel Contention Graph (MCCG) is proposed to characterize the impact of interference under the protocol interference model.
