“…The authors use dynamic programming approach to minimize a cost related to energy, subject to various delay constraints, such as a deadline by which all packets must be sent. Satellite NDMA (S-NDMA) [10] assumes a Demand Assigned Multiple Access (DAMA) medium access control (MAC) protocol, and uses the channel statistical information to define the number of packets transmissions separated by a round trip times (RTTs), such that the energy consumption is minimized and a set of QoS requirements is met. However, these schemes discuss the energy allocation of the single satellite, not the whole satellite constellation.…”

As the backbone of transmission networks, satellite networks need to support a variety of services to meet the demands of new businesses and functions. Because of the characteristics of the satellite network, the services provided to users are also divided into multiple priorities. Thus, the quality of service (QoS) requirements for information in the satellite network will be more stringent. To this end, the space-based QoS-guaranteed model should have strong expansibility. Based on an analysis of the performance evaluation standards of QoS systems in a satellite network, this paper proposed a comprehensive evaluation criterion, and the simulation results show that this criterion could guarantee the QoS for various businesses in the satellite network.

“…Most of the studies on dynamic transmission power controls on satellite stations involves on‐board energy saving, regardless of investigations on controlling the imposed interferences on the victim receiver. For example, focus on energy saving of the batteries on the satellite boards as a single unit. Whereas, considers the energy consumption reduction of eclipsed satellites constellations as a whole system.…”

Summary The coexistence of geostationary satellite orbit (GSO) and non‐GSO (NGSO) fixed satellite service systems within the same spectrum to enhance the spectrum efficiency in Ka band has attracted many interests lately. However, the coexistence of GSO‐NGSO satellite systems with limited shared spectrum can cause in‐line interference from a satellite to other satellite's earth terminals. In this context, this contribution investigates three possible power control approaches to mitigate the in‐line interference caused by an NGSO satellite to the GSO earth terminal, while the NGSO satellite is crossing the GSO satellite's illumination zone. Moreover, three types of interference mitigation techniques, namely, range‐based, traffic‐aware, and cognitive power control techniques are investigated. Furthermore, to increase the spectrum efficiency of the GSO‐NGSO fixed satellite service terrestrial network, we formulate and solve an optimization problem with the objective of minimizing the inter‐site distance between earth user‐terminals. More specifically, we find the minimum distance from a GSO earth terminal, where an NGSO earth terminal can be implemented subject to minimizing received interference level at the victim system. Finally, our comparative results show that the cognitive power control technique performs the best in protecting the victim receiver from the in‐line interference.
