Abstract

A satellite communication system is an excellent candidate toprovide broadband integrated Internet services to globallyscattered users. The inter-operation between a satellite systemand the existing terrestrial Internet infrastructure introducesnew challenges at different layers. Automatic Repeat reQuest (ARQ)techniques have been introduced at radio link layer to improve theperformance of Transport Control Protocol (TCP)/IP over wirelessterrestrial links, but these techniques are usually dismissed inpresence of high latency links such as satellite links. In thispaper, we will show that a truncated power control can effectivelyimprove the trade-off delay-residual error after retransmissionsand makes ARQ techniques a feasible solution for error control insatellite links. Furthermore, mobility management issues inpresence of satellite diversity are addressed. Performance of anInter-Segment Hand-Over (ISHO) procedure, in terms of propagationdelay, will be carried out through simulation for different spacesegment configurations.
