An analysis of hidden node problem in IEEE 802.11 multihop networks

Prevailed IEEE 802.11 WLAN has been applied widely to wireless multihop networks, but its performance degraded severely from well-known hidden node problem. This paper proposes a novel analysis based on simple mathematical model for the hidden node problem which is classified as two typical cases, this is, the situations within or out of carrier sense ranges among hidden nodes. Our model is, our model is quite simple against existing complex models, but is well matched as the simulation results using NS2 for the performance evaluation.
