| description | In this paper, we present an end-to-end QoS
simulation studies on internetworking of remote LAN and long
range communications over LEO-Iridium satellites constellation
taking SuperJARING network in Malaysia as an example. A
macro level network simulation scenario based on actual network
topology in Malaysia is implemented as Diffserv network model
using the network simulator-2 (NS-2). Web traffic (HTTP) is used
as the internet traffic models in the simulation analysis. All
simulations are carried out in error-free and link-loss
environment. In error-free simulations, the accumulative network
traffic loads are varied from 20%, 50% and 80% while in link�loss environment simulations only 20% traffic load is used with
bit error rate (BER) varied from 1x10-5
, 1x10-4 and 2x10-4
. We
compare the empirical TCP throughput traces with analytical
model for validation. The results show clearly that QoS can be
achieved with IP Diffserv over satellites constellation like Iridium. |
