“…In Ref. [3], busy tone based cooperative (BTAC) protocol based on CoopMAC is proposed in which a busy tone signal instead of helper-to-send (HTS) that is in CoopMAC is used in order to reduce overheads. However, the shortcoming of BTAC is that the neighboring nodes cannot accurately get network allocation vector (NAV) which causes increase of packet collisions.…”

A novel adaptive cooperative medium access control (MAC) protocol, which is completely backward compatible with the legacy IEEE 802.11 distributed coordination function (DCF), is proposed in this paper. To adapt to dynamic channel variation and network topology, the sender adaptively selects transmission scheme based on the instantaneous channel measurements. Analytical and simulation results show that the proposed protocol outperforms the existing one in terms of throughput, delay, energy and mobility.

“…Current studies on cooperative communication focus on relay selection , energy efficiency, and power and resource allocation . Studies have carried out preliminary work on media access control (MAC) design for cooperative communications. Among these studies, a cooperative triple busy tone multiple access (CTBTMA) combines request to send/clear to send (RTS/CTS) and busy tone.…”

Cooperative communication has attracted many research interests in recent years because it can take advantage of the broadcast nature of wireless communications and spatial diversity to improve the network performance. Although relay nodes in cooperative communications can help improve the performance, relay nodes may cause the serious competition on wireless channel accessing, which makes the channel access problem in cooperative communications challenging. To solve this problem, based on cooperative triple busy tone multiple access, this paper proposes a media access control scheme that concurrently combines the request to send/clear to send and busy tone with a proper tone duration timer. In the scheme, three busy tones are proposed to coordinate the nodes in the network to transmit packets, which is further utilised to solve the hidden terminal and exposed terminal problems in cooperative communications. Among the three busy tones, the cooperative busy tone is set according to the relay's signal‐to‐noise ratio. Based on the busy tone, this paper also proposes a bandwidth efficient relay selection algorithm, in which the source node can select the best relay in a distributed way by monitoring the busy tone. The simulation results demonstrate that the proposed scheme can largely reduce the blocking time and improve the channel utilisation in wireless cooperative networks.

“…However, in this protocol neighboring nodes with low rate transmission capability can also unnecessarily participate in the contending process, leading to wasted network resource. Different from the above protocols, the BTAC protocol in [8] uses a busy tone signal of short length for the helper to inform the source about its availability. This protocol can reduce the overhead of exchanging control frames between the helper and the source.…”

This paper considers the design of a cross-layer medium access control (MAC) protocol for wireless ad hoc cooperative networks. Specifically, we redesign the message exchange process of the MAC protocol previously proposed by Shan et al. By using a HRP signal with shorter length the proposed protocol can reduce the protocol overhead and thus improve the transmission reliability. We also propose to use only one HRP signal to resolve the collision among the helpers with the same cooperative rate. The proposed protocol achieves higher path throughput and lower end-to-end packet latency compared with that by Shan et al. and the traditional IEEE 802.11 MAC protocol.
