Abstract	Interferences in an ad-hoc network can be defined as a set of constraints that specify which groups of nodes cannot transmit simultaneously, and they have significant implications for the network capacity and other performance measures. This paper expounds the difference between two types of interferences: 1) physical interferences due to the receiver's inability to decode a signal when the powers received from other signals are large; and 2) protocol interferences imposed by the specific multi-access protocol being used to coordinate transmissions of nodes. We model interference types 1 and 2 in terms of graphs. Based on the insights obtained, we devise a scheme that modifies 802.11 slightly to make its capacity scale with the number of nodes.
