“…In OC MAC and SCA MAC initially all nodes reside on a global common control channel and performs three way handshake to select data channel from the FCL and confirms the data transmission through an acknowledgement [11,12]; whereas C-MAC selects R channel within the white spaces and sets this channel as a control channel and manage the communication on R channel [13]. DOSS-MAC makes use of 3 transmitters and presents a control channel algorithm to enable coordination among cognitive nodes and implements network layer multicasts [14].…”

“…Some protocols make use of GCCC for FCL exchange and suffers from all the disadvantages explained in II above [10,11,12,17]; the other method is to intelligently decide a local CCH within the available spectrum holes and advertise this to other nodes. This method which is already used by [16,20] however lacks clear methodology of finding the CCH within the white spaces amongst cognitive nodes.…”

Abstract-The radio spectrum (3kHz -300GHz) has become saturated and proven to be insufficient to address the proliferation of new wireless applications. Cognitive Radio Technology which is an opportunistic network and is equipped with fully programmable wireless devices that empowers the network by OODA cycle and then make intelligent decisions by adapting their MAC and physical layer characteristics such as waveform, has appeared to be the only solution for current low spectrum availability and under utilization problem. In this paper a novel Dynamic De-Centralized Hybrid "DDH-MAC" protocol for Cognitive Radio Networks has been presented which lies between Global Common Control Channel (GCCC) and non-GCCC categories of cognitive radio MAC protocols. DDH-MAC is equipped with the best features of GCCC MAC protocols but also overcomes the saturation and security issues in GCCC. To the best of authors' knowledge, DDH-MAC is the first protocol which is hybrid between GCCC and non-GCCC family of protocols. DDH-MAC provides multiple levels of security and partially use GCCC to transmit beacon which sets and announces local control channel for exchange of free channel list (FCL) sensed by the co-operatively communicating cognitive radio nodes, subsequently providing secure transactions among participating nodes over the decided local control channel. This paper describes the framework of the DDH-MAC protocol in addition to its pseudo code for implementation; it is shown that the pre-transmission time for DDH-MAC is on average 20% better while compared to other cognitive radio MAC protocols.

“…Many multi-channel MAC protocols [4], [5], [6], [7], [8], [9] assign one dedicated control channel to enable the other interfaces to switch and transmit on pre-arranged channel from control channel. These protocols typically consist of a least two or more radio interfaces: one interface has to be tuned to a fixed common channel for control purposes, while the other interfaces can be dynamically switched between the remaining channels for data exchange.…”

“…al. explored the cognitive radio context and proposed a CSMA/CA based cognitive MAC protocol which is known as Statistical Channel Allocation MAC (SCA-MAC) [9]. Similar to other common channel rendezvousing schemes, SCA-MAC utilizes a common channel for initiating hand-shaking, while DATA/ACK messages are transmitted over data channel.…”

The rapid diminishing in the cost of commodity wireless hardware in recent years has prompted the use of multiple radios to improve the capacity of wireless networks. However, the research has shown that the improvement obtained from using multiple radios does not solely depend on the number of radios, but primarily on how these radios can be integrated in a constructive manner. A common way of integration multiple radios is to use a dedicated radio for control. To date, a number of multi-radio MAC protocol are employing a dedicated radio to control and coordinate the other radios, though the approaches are varied from one to another. In this paper, the control separation techniques in the multi-radio multi-channel MAC have been surveyed, and a classification of control separation techniques is provided. Moreover, this study points out the open research issues and intends to spark new interests and developments in this field.

Abstract-In this work, we investigate a statistical approach for dynamic spectrum access and radio resource management (RRM) in opportunistic cognitive radio (CR) networks. We propose a distributed MAC protocol for such networks that enables unlicensed users to dynamically utilize the available spectrum while limiting the imposed interference on primary (PR) users. Our proposed protocol is novel in three aspects. First, it does not require CR users to coordinate with PR users. Second, it does not assume any predefined CR-to-PR power mask, and thus can exploit the available spectrum more efficiently. Third, it provides the PR users with a statistical guarantee on the fraction of time that their reception may be corrupted by CR users. To avoid corrupting PR user receptions, the protocol computes the maximum power that a CR transmission can use based on current network conditions. We show how to compute this maximum power by deriving models for the PR-to-CR and PR-to-PR interference. Simulation experiments illustrate that our MAC protocol can satisfy the statistical guarantee for PR users under various user deployment models and traffic loads.
