Dynamic spectrum access in open spectrum wireless networks
TLDR
A random access protocol is proposed that is shown to achieve airtime fairness and a distributed version of this protocol that uses only local information is proposed based on homo egualis anthropological model.Abstract:
One of the reasons for the limitation of bandwidth in current generation wireless networks is the spectrum policy of the Federal Communications Commission (FCC). But, with the spectrum policy reform, open spectrum wireless networks, and spectrum agile radios are set to drive next general wireless networks. In this paper, we investigate continuous-time Markov models for dynamic spectrum access in open spectrum wireless networks. Both queueing and no queueing cases are considered. Analytical results are derived based on the Markov models. A random access protocol is proposed that is shown to achieve airtime fairness. A distributed version of this protocol that uses only local information is also proposed based on homo egualis anthropological model. Inequality aversion by the radio systems to achieve fairness is captured by this model. These protocols are then extended to spectrum agile radios. Extensive simulation results are presented to compare the performances of fixed versus agile radios.read more

Stable Throughput of Cognitive Radios With and Without Relaying Capability
TL;DR: A scenario with two single-user links, one licensed to use the spectral resource (primary) and one unlicensed (secondary or cognitive), is considered and benefits of relaying strongly depend on the topology of the network.

Decentralized cognitive mac for dynamic spectrum access
TL;DR: Decentralized cognitive medium access control protocols are presented that allow secondary users to recognize spectrum opportunity and transmit based on a partial observation of the instantaneous spectrum availability.

Analysis of Cognitive Radio Spectrum Access with Optimal Channel Reservation
TL;DR: A channel reservation scheme for cognitive radio spectrum handoff allows the tradeoff between forced termination and blocking according to QoS requirements and can greatly reduce forced termination probability at a slight increase in blocking probability.

An anti-jamming stochastic game for cognitive radio networks
TL;DR: The proposed stationary policy in the anti-jamming game is shown to achieve much better performance than the policy obtained from myopic learning, which only maximizes each stage's payoff, and a random defense strategy, since it successfully accommodates the environment dynamics and the strategic behavior of the cognitive attackers.

What and how much to gain by spectrum agility
TL;DR: This paper proposes three basic building blocks for spectral-agile systems, namely spectrum opportunity discovery, spectrum opportunity management, and spectrum usage coordination, and develops protocols for each blocks, and proposes protocols that can improve the throughput of an IEEE 802.11 wireless LAN.
