Abstract:
A Multi-Satellite Broadband Network (MSBN) appears to be a promising network for providing efficient and seamless multimedia services. To maximize the resource utility and optimize the Quality of Service (QoS) in MSBN, reasonable bandwidth allocation method is, indeed, important. State-of-the-art bandwidth algorithms, which are mostly based on the allocation of a single satellite-ground link, ignore limited traffic capacities in other links, such as inter-satellite links. In this paper, a Multi-Pool based Bandwidth Allocation (MPBA) scheme is proposed to solve this problem. Firstly, a typical multi-pool framework is built to manage bandwidth resources of all communication links instead of the traditional single satellite-ground link, and the corresponding resource allocation process is analyzed. Secondly, inspired by the non-cooperative game theory, the MPBA algorithm with a low computation complexity is designed to ensure different QoS demands of multimedia services. Extensive experiments are carried out, and results obtained demonstrate that our multi-pool framework can achieve improvement on the end-to-end delay and the network resource utility over existing bandwidth allocation methods in MSBN.
