Distributed Coordination Function (DCF) is a well-known 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...
Due to the nature of water, instead of radio wave, sound wave is used for transmission in underwater wireless acoustic networks (UWANs). Based on the analysis of this paper, comparison to the performance in wireless ad hoc networks, hidden terminal problem and exposed terminal problem have a higher impact on that in UWANs. In this paper, a Channel Stealing MAC (CS-MAC) protocol is proposed not only...
In terrestrial wireless networks, station (STA) adopts virtual carrier sensing mechanism to avoid hidden terminal problem. The neighbors which had received RTS/CTS will set a Network Allocation Vector (NAV) and suspend the transmission in NAV duration to avoid data collision. Due to the impacts of low data rate and long propagation delay, setting NAV duration in the underwater acoustic networks (UANs)...
Carrier sensing mechanism has been adopted in IEEE 802.11 MAC for collision avoidance under single channel based wireless ad hoc networks. However, due to the hardware limitation, the carrier sensing mechanism can not help much in single transceiver and multi-channel scenarios. In this paper, we propose a pipelining multi-channel (pi-Mc) MAC protocol for multi-channel ad hoc networks. The core idea...
The paper proposes a multi-rate supported power control, named MRPC, MAC protocol to avoid the LIRC (Large Interference Range Collision) problem for wireless ad hoc networks. The main concept of the MRPC protocol is to protect the current reception by means of the carrier-sensing range of the previous transmission to cover the induced interference range of the current reception. Based on the concept,...
