Channel bonding (CB) is a technique that enables a wireless link to combine channels and achieve higher data rates. In this paper, competition for efficient spectrum access among autonomous users with heterogeneous CB capabilities is considered. Specifically, we propose distributed and coordinated channel/bonding selection methods under signal-to-interference-plus-noise ratio (SINR) and collisionprotocol models. In our methods, users utilize only limited feedback to distributively arrive at CB selections that minimize their probability of conflict. The proposed method utilizes a novel channel quality metric, which is based on the ratio of noise power to the sum of interference and noise power. It is shown that CB can lead to higher data rates, and it is most beneficial when users have a high SINR. However, it is also shown that as the ratio of users to available channels increases, CB performance degrades. Our results show that under certain scenarios, the proposed coordinated and distributed channel/bonding selection schemes help users converge fast to conflict-free channel selections as compared to the other channel/bonding selection schemes. Moreover, the proposed schemes result in considerably superior performance to existing CB schemes in terms of network data rate.

“…2) Delay Minimization: By implementing intelligent CB, the transmission delay can be minimized as large bandwidth becomes available so data is transmitted at higher rate [72]. Consider a hospital environment where several types of medical equipment send their data to the central control, and possibly the data center.…”

“…By incorporating an increased bandwidth upon user requirement, the advantage of adaptive bandwidth and adaptive data rate [73] is achieved and user can dynamically select the bond size. In this way, the throughput of the communication system can be maximized [70] and end to end delay can be minimized [72] keeping in view the system limitations.…”

“…7, to make single broadband channel, as seen in IEEE 802.11n [127]. Both approaches have their benefits and limitations, for example, the multi-channel approach attempts to minimize traffic congestion whereas the CB approach attempts to increase the throughput [72]. CB can utilize both licensed and unlicensed bands [4] where contiguous channels can be found and assigned to CR nodes opportunistically.…”

Abstract-Channel bonding (CB) is a proven technique to increase bandwidth and reduce delays in wireless networks. It has been applied in traditional wireless networks such as cellular networks and wireless local area networks along with the emerging cognitive radio networks. This paper first focuses on providing a survey of CB schemes for traditional wireless networks such as cellular networks, wireless local area networks and wireless sensor networks, and then provides a detailed discussion on the CB schemes proposed for cognitive radio networks. Finally, we highlight a number of issues and challenges regarding CB in cognitive radio sensor networks and also provide some guidelines on using CB schemes in these futuristic networks.
