Satellite transport protocol handling bit corruption, handoff and limited connectivity

M.E. Elaasar, M. Barbeau, E. Kranakis, Zheyin Li
2005 IEEE Transactions on Aerospace and Electronic Systems  
Being both wireless and mobile, low Earth obiting (LEO) satellite access networks have a unique set of link errors including bit corruption, handoff, and limited connectivity.  ...  A recent study proposed a new transport protocol for satellites called STP that addresses many of the unique problems of satellite networks.  ...  In some cases, the RTT can moderately vary (for example due to LEO satellite mobility). The extended RTTs can wrongly be interpreted as an effect of congestion.  ...
