A Hybrid Many-to-Many Communication Multi -Channel MAC Protocol for Ad Hoc Networks

Some multi-channel medium access control (MAC) protocols have been proposed to provide more efficient communication in ad hoc networks. In addition, each communication channel can be shared simultaneously among several nodes through techniques such as multiple-input multiple-output (MIMO) and frequency division multiple access (FDMA), making the IEEE 802.11 Standard-based technology suitable for multipacket transmission and reception (MPTR). This paper presents a new Hybrid and Adaptive Approach to the Many-to-Many Communication Multi-channel MAC Protocol (H-M2MMAC) based on the Split Phase scheme of the IEEE 802.11 Power Save Mode (PSM). Beyond using the communication phase to transmit data, it enables the transmission of data during the negotiation (or control) phase under high load conditions. The results show that H-M2MMAC has superior throughput performance compared with related multi-channel protocols.
