HAP-Satellte architecture supporting efficient multilayered routing

The integration of different layered network is one of the most feature in the next telecommunication systems, for this reason the paper explains the potential role of an integrated satellite-high altitude platform (HAP)-terrestrial system proposing a new multilayered inter HAPs satellite routing algorithm (IHSR) integrated with an efficient admission control scheme in order to guarantee an adequate quality of service to multimedia traffic connections. The performance of the IHSR algorithm is evaluated through intensive simulations comparing it with a previous classical routing scheme under several traffic load scenarios. The obtained results demonstrate that the proposed strategy achieves an improvement in the inter-hap links utilization managing a greater number of active connections without decrease the offered QoS degree.
