Modeling multicast packet losses in wireless LANs

Experiments with an IEEE 802.11 wireless LAN show that the packet losses at multiple nodes can exhibit a certain degree of correlation. Analysis and simulation results show that conventional packet loss models do not adequately capture the loss characteristics exhibited in experimental traces. This paper proposes a new approach for modeling packet losses that explicitly accounts for spatial loss correlation. The improved accuracy of the new approach, compared to conventional models, is demonstrated by comparing results of simulations and experiments.
