Abstract

Signal statistics are modelled in an environment of shadowing and ground wave path loss. This propagation model is used to investigate the channel performance of a slotted Aloha network. The results are presented as receiver capture proability vs. packet propagation distance, with the log-normal variance and the offered traffic as parameters. Log-normal spatial distributions and uniform distributions of users over the coverage area are compared. The former facilitate the analysis of mobile packet-radio channels with near-far effect and shadowing and can often approximate the latter type of distribution. It is shown that stability and throughput cannot be realistically studied by (quasi-) uniform distributions. The log-normal subscriber density with a spatial spread of 8.68 dB gives a viable alternative to the study of the heavily loaded collision-type multiple-access channel.
