Saturation throughput of IEEE 802.11 DCF in multi-hop ad hoc networks

IEEE 802.11 DCF has been widely used in wireless multi-hop ad hoc networks as the medium access control protocol. However, how well it can perform has not been well studied. In this paper, we first propose a new Markov chain model to analyze the per-node throughput by taking into consideration three important issues in multi-hop networks, i.e., physical carrier sensing threshold, signal-to-interference plus noise ratio threshold, and hidden terminal problems. Then, we validate our analytical model by simulations. We find the simulation results match our theoretical results well.
