Abstract
This paper presents the evaluation performance of a hybrid satellite constellation network which provides internet access based Transport Control Protocol (TCP). The evaluated satellite network uses the constellation topology operating on Low Earth Orbit (LEO). The COMMStellationTM satellite system implemented using network simulator 2 (NS-2). In this paper, we modified a congestion window control based on TCP Westwood. The results show that the proposed technique reduces end-to-end (E2E) delay of transmitting packets. Hence the number of retransmission packets reduced.
Highlights
The trend of broadband Global Area Network (GAN) is a global satellite internet network
We present the simulation results comparing with the Transport Control Protocol (TCP) New Reno [4], the TCP Westwood [9], and the TCP Westwood-SS protocols
It has evaluated the performance in terms of congestion window and slow start threshold
Summary
The trend of broadband Global Area Network (GAN) is a global satellite internet network. (2014) The COMMStellationTM Satellite Constellation for Broadband Communication System Model in NS-2. Pongpadpinit constellation, it connects rural and remote areas of the world where fiber infrastructure is cost limiting. The initiative of the COMMStellationTM is to supply, produce, deploy and perform the COMMStellationTM constellation of satellites designed to prepare high speed network communications to global customers. It is designed to provide internet backhaul in an area where optical fiber networks do not exist. In this application typical customers consist of existing network of private customers. By using COMMStellation satellite, which provides high speed backhaul, each ISP only needs to connect their existing network to utilize the satellite system.
