Interference analysis for wireless ad hoc networks

We present interference analysis for wireless ad hoc networks and show that, depending on the path loss parameter (alpha), the average signal-to-interference ratio (SIR) either remains constant, or decays, when the number of interferers scales to infinity in the network, for nodes communicating with their close neighbors. Thus, communication is feasible in dense networks as long as alpha > 2 and a node attempt to transmit to other nodes located close enough so that interference can be overcome. An analytical model for interference is described and Monte-Carlo simulations validate our results.
