Resource Management in Satellite Networks part 8. This book provides significant knowledge on innovative radio resource management schemes for satellite communication systems that exploit lower layer adaptivity and the knowledge of layer 3 IP QoS support and transport layer behavior. The book integrates competencies considering all the parts of system design: propagation aspects, radio resource management, access protocols, network protocols, transport layer protocols, and more, to cover both broadband and mobile satellite systems | Chapter 2 ACTIVITY IN SATELLITE RESOURCE MANAGEMENT 49 References 26 and 27 present an algorithm for resource allocation in satellite networks to obtain time frequency plans for a set of terminals with a known geometric configuration under interference constraints. The goal is to maximize the system throughput while guaranteeing that the different types of demands are satisfied each type using a different amount of bandwidth. The proposed algorithm relies on two main techniques. The first generates admissible configurations for the interference constraints whereas the second uses linear and integer programming with column generation. In 28 the authors consider the problem of how a Geostationary Earth Orbit GEO satellite should assign bandwidth to several service providers operators so as to meet some minimum requirements on one hand and to perform the allocation in a fair way on the other. They provide a computational method to optimize allocation fairness in polynomial time taking practical issues into account. References 29 and 30 consider the problem of allocating the uplink bandwidth of a satellite transponder among hierarchies of Earth stations for guaranteed bandwidth and best-effort traffic types. CAC actions are taken locally at the Earth stations within the allocated bandwidth partition which is recomputed either periodically or upon request by considering dynamic variations in traffic and channel parameters with a cross-layer interaction between physical and MAC layers . The work in 31 32 proposes a new DiffServ-based scheme of bandwidth allocation during congestion termed Proportional Allocation of Bandwidth PAB . This method can be used in satellite networks based on GEO MEO and LEO Low Earth Orbit constellations in order to transport IP traffic and to provide QoS. In PAB during congestion all flows get a share of IP available bandwidth proportional to their subscribed information rate. Reference 33 considers an architecture to interconnect remotely .
