Modeling of Inter-Satellite Link Protocol for Satellite Constellation

Abstract

This paper presents simulation results of Inter-Satellite Link (ISL) protocol for satellite constellations. The 4-satellite trail ISL model simulated by NS-3 provides results of quantitative packet throughput and amounts of packet loss on the ISL protocol based on the IEEE 802.11 standard. Based on transmission control protocol/internet protocol (TCP/IP) with increased inter-frame parameters, four-way handshake message signaling brings packet re-transmission to cope with packet loss. The simulation results show a correlation between the slot time, the uplink data rate, and the ISL throughput in the satellite topology.
