Estimate of mean C/I and capacity of interference limited mobile ad-hoc networks

Abstract

A theoretical estimate of the capacity of interference limited mobile ad-hoc networks (MANET), without an interference cancellation scheme, is given. The calculation is carried out using a realistic propagation model, a simplified system model and statistical consideration of mobile distances. An expression for the average carrier-to-interference ratio is then derived. This is subsequently used with the Shannon limit to determine the capacity. Expressions are given for calculating the dependence of throughput on availability and propagation.
