Spatial distribution of traffic in a cellular mobile data network
Jean‐Paul M. G. Linnartz · TU/e Research Portal · 1987
The position of a mobile terminal has a significant influence on its probability to capture the central receiver in the base station of a cellular radio system using slotted ALOHA for multiple access.Integral transforms of the probability density function for the received power prove a useful tool for analysing the relation between the spatial distributions of offered and throughput packet traffic in a mobile radio network with Rayleigh fading channels.A newly developed method to obtain the spatial distribution of throughput traffic from a prescribed spatial distribution of offered traffic is presented and illustrated with examples.Incoherent and coherent addition of interference signals is considered.The channel behaviour for heavy traffic loads is studied.In both the incoherent and coherent case, the spatial distribution of offered traffic required to ensure a prescribed spatially uniform throughput is synthesised numerically.
