Multi-spot beam satellite network can achieve the power and bandwidth gain of parallel multi-beam with the appropriate resource management. The effective resource management is important not only to prevent the unnecessary resource waste but also to increase in the resource utilization efficiency in the satellite systems with limited resource environment. In this paper, we refer two resource management schemes adjusting power and bandwidth of parallel multi-beam, in order to achieve the substantial performance gain and reasonable proportional fairness. These schemes dealt with the tradeoff problem between different aims of system objectives. In this paper, we compare the performance of these schemes, and investigate the gaps of those that are shown according to amount of traffic overload and dominant resource. The performance is evaluated by taking into account the impact to the system environment, and we propose a possible approach to the adaptive resource management method in the multi-beam satellite networks. © 2013 IEEE.
