Satellite Link Capacity Planning in Mobile Networks

Taking into account continuous increase of traffic demands, it is necessary to increase satellite link capacity rationally, minimizing the total expansion cost. The capacity shortages are allowed so the problem is denoted as CEPS (Capacity Expansion Problem with Shortages). Efficient algorithms for sizing of N satellite links in mobile networks during exploitation are being developed. With different approach for allowed capacity state values we developed and tested some algorithm options. Through many numerical examples their results are compared with algorithm that can provide an optimal result. It is obvious that heuristics are very effective and for some examples they are capable to find the optimal result. The algorithms can be applied to short- or medium-term satellite network planning with finite number of discrete time periods
