Near-optimal packet scheduling scheme in satellite LTE networks

This study proposes a near-optimal packet scheduling scheme in the satellite long term evolution (LTE) network which uses multiuser multiple-in multiple-out technique. For the available resources in the satellite LTE network to be fully utilised and in order to meet the set targets of 4G standard, the need for an optimal scheduling scheme that will maximise the throughput without compromising the quality of service and fairness of users is very crucial. The aim of this study is to propose near-optimal scheduling schemes that have been obtained using Karush-Kuhn-Tucker multipliers and compare their performances with other throughput-optimal scheduling schemes. A new metric that can be used to compute the overall performance of the scheduling schemes is also presented. This work has adopted the use of a land mobile dual-polarised GEO satellite system.
