A DTN approach to satellite communications

IEEE Journal on Selected Areas in Communications, 2008
Satellite communications pose serious challenges to transport layer performance, mainly because of long propagation delays (especially in geosynchronous systems) and the possi ble presence of random errors on the satellite link. Solutions that cope with these impairments usually rely upon either the adoption of enhanced versions of transport protocols,

Throughput of a satellite channel communication

Acta Informatica, 1985
The throughput of a satellite channel communication is depending upon the link protocol. It is well known that the ''classical'' HDLC protocol is inadequate when applied to satellite links instead of short terrestrial links. Several modifications have been proposed to overcome this problem.

Lunar communication satellites

Communications Satellite Systems Conference, 1966
Abstract Exploration of the surface of the moon and successful operation of lunar bases in the 1970's and beyond will depend on reliable, long-range communication over the lunar globe as well as between the earth and moon. A system of communication satellites in lunar orbit can provide the communications needed over the moon's surface.
