Congestion Control in Deep Space Communication

Priyaam Das, Jonnagaddala Jagruthi, K. Malathi

Abstract: Space Exploration has being attracting since early 20th century. Long propagation delay at the planetary nodes introduces new challenges to the congestion control. In this paper we take advantage of long propagation delay; which is utilized as a memory space. Instead of dropping the packets they are sending back to the source; this reduces the packet loss. Two proposed methods in this paper are: Reverse channel with and without rate control will be compared to get the better result.

Keywords: reverse channel, deep space, space exploration, memory space
