Throughput and Delay Analysis of Multihop IEEE 802.11 Networks with Capture
In this paper, we present an analytical model for the approximate calculation of the throughput and end-toend delay performance in single hop and multihop IEEE 802.11 networks under uniform traffic distribution while accounting for the effect of aggregate interference and capture. We do this using a “major interferer approximation” approach where we approximate the aggregate interference by the interference caused by the closest interferer only. We then calculate the network throughput rate by modeling the CSMA/CA MAC channel state process as a regenerative stochastic process. To compute the distribution of the incurred packet end-to-end delay, we use the regenerative process modeling approach to calculate the moments of the effective packet service time; we then apply the latter through the use of an M/G/1 queuing system model to calculate the average and standard-deviation of the packet’s waiting time in each node’s queue The effect of capture is taken into account in calcula...
