Sažetak
Introduction of new generation of satellites in mobile networks (e.g. Inmarsat) is good chance for LES (Land Earth Station) to expand its link capacities in the next exploitation period. This is only way how LES can ensure more simultaneous connections and rise the traffic to his partner LESO (Land Earth Station Operator). Resource management process in LES is firmly correlated with traffic prediction. LESO needs very effective optimization tool for good utilization of link capacities (arranged from LES) in the next planning period. The efficient heuristic algorithm for optimal capacity sizing of N satellite links in the finite time period is being developed, minimizing the total expansion cost. In the same time it ensures fulfillment of traffic demands with minimal exploitation loss caused by presence of idle capacities. It means that our heuristic approach can be successfully applied to short-term or medium-term satellite network planning.
