Wireless ad hoc networks have received significant attention in recent years due to their easiness to setup and their potential applications in many domains. Such networks can be useful in situations where there is not enough time or resource to configure a wired network. The shared media used by wireless networks, grant exclusive rights for a node to transmit a packet. Access to this media is controlled by the Media Access Control (MAC) protocol. These protocols are of significant importance since the wireless communication channel is inherently prone to errors and unique problems such as the hidden-terminal problem, the exposed-terminal problem, deafness and signal fading effects, etc.
