“…However, time synchronization which is necessary for [6]- [10] is not easily achieved in distributed wireless ad hoc networks. As a result, a channel hopping scheme (π-MAC) proposed in [12] not only can reduce hardware cost but also does not require synchronization mechanism. The main idea of π-MAC is that a transmission procedure will be divided into many subtransmissions.…”

Distributed Coordination Function (DCF) is a wellknown MAC protocol for single channel wireless ad-hoc networks. However, hidden terminal and false blocking problems may happen if DCF is directly applied to multi-channel environments. As a result, the paper proposes a Multi-group Multipipeline Multi-channel MAC protocol (3M MAC) for wireless multi-channel ad-hoc networks to avoid multi-channel hidden terminal and false blocking problems. 3M MAC divides a transmission into several subtransmissions. Each subtransmission is transmitted sequentially on all channels. Under this pipelinelike scheme, we further analyze the impact of the channel switch time and DATA packet size on network performance. Based on the analyzed results, a channel leak problem will happen to decrease the performance in case that the number of channels is large. The main concept of 3M MAC is to classify channels into groups to alleviate the channel leak problem. Finally, we compare 3M MAC with three well-known multi-channel MAC protocols and IEEE 802.11 DCF. Simulation results show that 3M MAC has the best performance in network throughput and transmission delay.

“…If needed, channel state tables are set up based on the overhearing of RTS/CTS packets [1][2][3]6]. Thirdly, the channel hopping of each node is arranged according to a fixed channel hopping scheme [5] or pseudorandom channel hopping scheme [7]. Fourthly, each node observes a control channel (CCH) or a related DCH for the interval of data packet transmission before it initiates a data packet transmission [3,4].…”

A slot-optimised multichannel medium access control (SO-MMAC) protocol is proposed to resolve the multichannel hidden terminal problem and control channel (CCH) bottleneck problem for multihop ad hoc networks. It adjusts the relationship between the reservation slot (RS) on the CCH and the data packet transmission slot on the data channel (DCH) to achieve the best load balance and default collision-free DCH selection without establishing a channel state table, and then greatly enhances multiple access efficiency. A reservation scheme with minimum handshakes and RS and contention micro-slot backoff mechanisms is also proposed to effectively decrease control overhead and packet collisions. Simulation results show that SO-MMAC has better performance compared to the traditional MAC protocol.Introduction: Recently, multichannel medium access control (MAC) protocols have become a current hotspot owing to higher network performance than single-channel MAC protocols [1][2][3][4][5][6][7]. However, it incurs multichannel hidden terminal problems [1-5] and multichannel exposed terminal problems [6], which greatly decrease its multiple access performance. In general, five approaches are adopted to resolve these problems. First, multiple half-duplex transceivers are used [1]. Secondly, selected data channels (DCHs) are designated in request-tosend (RTS) and clear-to-send (CTS) packets [1][2][3][4]6]. If needed, channel state tables are set up based on the overhearing of RTS/CTS packets [1][2][3]6]. Thirdly, the channel hopping of each node is arranged according to a fixed channel hopping scheme [5] or pseudorandom channel hopping scheme [7]. Fourthly, each node observes a control channel (CCH) or a related DCH for the interval of data packet transmission before it initiates a data packet transmission [3,4]. Fifthly, acknowledgment (ACK) packets are transmitted on another CCH which is different from that of RTS/CTS handshakes [6]. Meanwhile, the application of a global positioning system (GPS) makes the time division multiple access (TDMA)-based MAC protocol possible in multihop ad hoc networks. In this Letter, we present a TDMA-based slot-optimised multichannel MAC (SO-MMAC) protocol with a halfduplex transceiver to avoid establishing a channel state table for multihop ad hoc networks.

IEEE 802.11 provides multiple channels for wireless communications at the physical layer, however the Medium Access Control (MAC) protocol is designed only for single channel. Moreover, the Carrier Sense Multiple Access (CSMA)‐based MAC protocol in IEEE 802.11 suffers from the starvation problem. By exploiting the multiple channels and employing the power control algorithm to increase the spatial reuse, we can improve the network performance. Motivated by this, herein we present multichannel MAC protocols and power control algorithms proposed for wireless ad hoc networks.
