Optimized routing protocol for broadband hybrid satellite constellation communication IP network system

Abstract

Long delays and varying delays in triple-play services on a hybrid satellite network are constraints lead for quality of service in end-to-end delay; it is an origin of jitter to make obstacle such as motion freezes and block artifacts in the video. In this paper, the Optimized Routing Protocol for Hybrid Satellite Network (ORPHSN) algorithm is proposed in order to reduce end-to-end delay and determine the best path. The proposed algorithm applies to COMMStellation™ system where hybrid satellite network topology with triple-play services of traffic load applied. The algorithm consists of five metrics which are (1) propagation link delay, (2) queuing delay, (3) link hop count, (4) link utilization, and (5) link length. The simulation results show that the proposed routing algorithm can determine the best routing paths. As a result, link performance is improved due to lower transmission delay and shorter end-to-end delay.
