The crucial contribution of the paper is the novel saturated throughput analysis of the IEEE 802.11 Distributed Coordination Function (DCF) in the presence of hidden stations. This approach involves a novel analytical model that is an extension to previous papers by other authors which provide Markov chain analysis to IEEE 802.11 DCF. Hidden stations cause most collisions because stations cannot sense each other's transmission and often send packets concurrently, resulting in significant degradation of the network performance.
