Abstract

In this paper, we provide a performance model and viable evaluation for the Adaptive Modulation and Coding (AMC) used in High Altitude Platforms (HAP) based HSDPA/UMTS telecommunication networks. We incorporate the HAP channel model into a new queueing model which is able to capture most of the features of wireless communications, such as traffic-burstiness, channel fading, channel allocation policy, etc., in an integrated way. In a case study we validate the model with the use of ns-2 simulator and also present numerical results to evaluate the impact of the HAP environment on the performance of HSDPA user terminal categories.
