Satellite Communications

This study is motivated by the need to give the reader a broad view of the developments, key concepts, and technologies related to information society evolution, with a focus on the wireless communications and geoinformation technologies and their role in the environment. Giving perspective, it aims at assisting people active in the industry, the public sector, and Earth science fields as well, by providing a base for their continued work and thinking

Performance evaluation of the PRRA MAC protocol for GEO satellite networks

The provision of acceptable Quality-of-Service (QoS) for integrated multimedia traffic over a geosynchronous earth orbit (GEO) satellite network demands the existence of a well-designed Medium Access Control (MAC) protocol. This paper proposes a new dynamic satellite bandwidth allocation technique (Predictive Resource Reservation Access PRRA) which is based on accurate videoconference traffic prediction. Our work is combined with another work on data traffic modeling and prediction and is shown to provide very good throughput and delay results, when compared with other efficient schemes from the literature and with an "ideal" satellite bandwidth allocation scheme
