Paper Abstract

The rapid development of onboard processing (OBP) pushes broadband satellite networks to carry on multimedia traffic. However, the function of onboard routing cannot be provided in existing satellite networks with inter-satellite links (ISLs), and Quality of Service (QoS) of the satellite networks cannot be reliably guaranteed because of great difficulties in processing of QoS service. In this paper, a two-layered LEO and MEO satellite network (LMSN) is presented. Based on the idea of time-slot division, a novel dynamic hierarchical and distributed QoS routing protocol (HDRP) is investigated, and an adaptive Bandwidth-constrained Minimum-Delay Path (BMDP) algorithm is developed to calculate routing tables efficiently by using the QoS metric information which is composed of delays and bandwidth. The performances of the LMSN and HDRP are also evaluated through simulations and theoretical analysis.
