Access Analysis of GEO, MEO, & LEO Satellite Systems [PDF]
, 2018 The goal of this study is to calculate access duration and intervals for three different kinds of satellite schemes to support a WSN (wireless sensor network). The first scenario involves only LEO-level satellites.

Distributed Load-Aware Routing in LEO Satellite Networks
IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008 In this paper, we propose a lightweight distributed routing algorithm, called Distributed Load-Aware Routing (DLAR). The proposed protocol adopts a distributed approach to handle the complexity of the satellite system and at the same time provides a hop-by-hop mechanism for splitting traffic load in order to alleviate the problem of congestion that ...

Routing In Leo-Based Satellite Networks
, 1999 Several strategies have been proposed for routing in a low earth orbit (LEO) satellite system. Some of them are based on the Internet Protocol (IP) and a few on asynchronous transfer mode (ATM) switching.
