Opportunistic relaying is an important relay selection scheme for cooperative communication, it can dynamically select relay depending on instantaneous channel condition, which is a especially suitable for distributed networks. Some cooperative MAC based on opportunistic relaying have been proposed to enhance the system throughput. However, since the throughput is normally related to their energy...
The paper presents a cooperative MAC based on opportunistic relaying for ad hoc networks. In the proposed MAC, the cooperative scheme will be activated on the condition that the source contended the channel successful, but the destination receives the inaccurate packets because of the channel noise. Based on opportunistic relaying, the neighbor which has the best channel condition to the destination...
