Performance Analysis of One-to-one WLANs in Grid Topology <Abstract> This paper presents analytical expressions using airtime concept for network throughputs and carrier-sensing duration of one-to- one WLANs in grid topology considering simultaneous transmission. Specifically, each network throughput can be obtained analytically by expressing frame-existence probabilities with respect to each node. The validity of the analysis is shown by the comparison with the simulation results. The analytical results and the simulation ones well agree. |
