Resource Management for 5G-satellite Communication Systems based on Queuing Theory

Nowadays, with the advent of new satellite services, the need for resourcemanagement in the emerging fifth generation satellite systems (5G-satellite) isinevitable. Thus, to solve this problem, the Bandwidth Manager for resourcereservation in satellite link is mandatory. On the other hand, due to limitedresources, their resource management is essential. In order to resource managementin 5G-satellite systems, can be applied in one phase or many phases, In this paper,resource management for 5G-satellite services is evaluated. The proposedoptimization problem is maximize mean response time under the propagationdelay constraints in satellite links. We solve the considered optimization problem viathe single phase and two phase algorithms. Finally, through simulation, theproposed algorithms are investigated and confirmed. In our scenarios, satellite is aCentral node in call flows and ground stations are End nodes in 5G-satellite basedon Internet protocol. So we simulated all of scenarios in matlab software for thisreason.
