Routing and Scalability Issues for Multi-layered Satellite-HAPs Networks

The main features of the future mobile communication systems are the provisioning of high-speed data transmissions (up to 1 Gb/s) and interactive multimedia services. For effective delivery of these services, the network must satisfy some strict quality-of-service (QoS) metrics, defined typically in terms of maximum delay and/or minimum throughput performances. According to this general vision, the integration of different layered network plays one of the most important roles in the next telecommunication systems, for this reason, the paper studies the performance of a routing algorithm, well suited for an integrated Satellite-High Altitude Platform (HAP) system, in terms of network dimension and scalability in order to guarantee an adequate quality of service to multimedia traffic connections.
