Review on free-space optical communications for delay and disruption tolerant networks

The increase of data-rates that are provided by free-space optical (FSO) communications is essential in our data-driven society. When used in satellite and interplanetary networks, these optical links can ensure fast connections, yet they are susceptible to atmospheric disruptions and long orbital delays. The Delay and Disruption Tolerant Networking (DTN) architecture ensures a reliable connection between two end nodes, without the need for a direct connection. This can be an asset when used with FSO links, providing protocols that can handle the intermittent nature of the connection. This paper provides a review on the theoretical and state-of-the-art studies on FSO and DTN. The aim of this review is to provide motivation for the research of an optical wireless satellite network, with focus on the use of the Licklider Transmission Protocol. The assessment presented establishes the viability of these networks, providing many examples to rely on, and summarizing the most recent stage of the development of the technologies addressed.info:eu-repo/semantics/publishedVersio

SATELLITE BASED DATA COMMUNICATION: A SURVEY

ABSTRACT Satellite communication is well known in providing best services where broadcasting is essential, where terrain is hostile and very sparsely populated. It also has niche where rapid deployment is very critical and important. In Global Network Infrastructure satellite is considered as an inseparable component of the communication infrastructure. A variety of research work has been explored and published for satellite based data communication & networking. It is utmost important to conduct a survey on different aspects and research issues of satellite based communication with a focus on the latest development. In this paper, we summarize, compare & comments on the approaches proposed for the satellite based data communication with keeping in view the parameters like Quality of service, Interplanetary Internet, Mobility management, explicit load balancing and packet reordering issue
