“…We assume exclusive spectrum sharing in our model, i.e., each 802.22 secondary network can use the spectrum band only if it is free interference of other secondary networks. This can be achieved via the 802.22 selfcoexistence mechanism as presented in [25]. Thus, n out of N spectrum bands are concurrently used by the 802.22 secondary networks.…”

Abstract-The cognitive radio enabled IEEE 802.22 wireless regional area network (WRAN) is designed to opportunistically utilize the unused or under-utilized TV bands. However, due to the open paradigm of cognitive radio networks and lack of proactive security protocols, the IEEE 802.22 networks are vulnerable to various denial-of-service (DoS) threats. In this paper, we study the coordinated DoS attacks on IEEE 802.22 networks from the malicious users' perspective. We formulate this problem from both a one-stage and a multi-stage scenario. In the one-stage scenario, we formulate a cooperative game among the malicious nodes and derive the optimal decision strategy for the them. In the multi-stage case, we propose a discretetime Markov chain model for the dynamic behavior of both malicious nodes and the 802.22 secondary networks. Simulation and numerical results demonstrate that in the one-stage case, the coordinated attack achieves 10-15% improvement compared to the non-cooperative attack from the perspective of malicious nodes, and, in the multi-stage case, there exists an optimal number of malicious nodes participating in the attack for the steady system to maximize the net payoff.

“…In [33], the self-coexistence of multiple overlapping IEEE 802.22 networks operated by multiple wireless service providers that compete for resources and try to seek a spectrum band without any interference from other coexisting IEEE 802.22 networks, was investigated from a game theoretic perspective. The dynamic channel switching was modeled as a distributed modified minority game (MMG), in which each user has to decide whether to leave a particular band or to continue using it when another user also appears in the same band.…”

“…The payment selection game among secondary users in [36] however is a non-cooperative game. For self coexistence among secondary users, while [33] proposes a non-cooperative dynamic channel switching game, [19] considers a cooperative approach for channel allocation. On the other hand, [34] considers a non-cooperative framework and a pricing based cooperative approach for self coexistence of secondary users.…”

“…In terms of resource allocation, while [14,36] consider the coexistence between primary service providers and secondary users, [19,33,34] explore self coexistence among secondary users. Although both [14,36] consider the coexistence between primary and secondary systems, [36] is based on the cooperation between primary and secondary users, while in [14], the framework is non-cooperative.…”

Efficient resource allocation is one of the key concerns of implementing cognitive radio networks. Game theory has been extensively used to study the strategic interactions between primary and secondary users for effective resource allocation. The concept of spectrum trading has introduced a new direction for the coexistence of primary and secondary users through economic benefits to primary users. The use of price theory and market theory from economics has played a vital role to facilitate economic models for spectrum trading. So, it is important to understand the feasibility of using economic approaches as well as to realize the technical challenges associated with them for implementation of cognitive radio networks. With this motivation, we present an extensive summary of the related work that use economic approaches such as game theory and/or price theory/market theory to model the behavior of primary and secondary users for spectrum sharing and discuss the associated issues. We also propose some open directions for future research on economic aspects of spectrum sharing in cognitive radio networks.
