This paper tries to bring together the physical model and protocol model that have been used to characterize interference relationship in an 802.11 ad hoc network. The physical model (known as the SNR model) is generally considered as a reference model for the physical layer behavior but its application in wireless ad hoc networks is restricted by its complication. On the other hand, the protocol model (known as the unified disk graph) is straightforward but its validity is doubtful.
