Minimum Distance Bandwidth Allocation for Data Traffic over Space Networks

The paper formalizes the bandwidth allocation process over space communication systems as a Multi – Objective Programming (MOP) problem and proposes an allocation scheme based on the GOAL programming called “Minimum Distance” (MD) algorithm. The method is aimed at following the performance obtained by each station when there is no conflict among the stations to access the channel. In short, the algorithm assigns the bandwidth so to approach a non-competitive situation as close as possible. It is tested over a faded channel by using only TCP/IP traffic. The performance evaluation is carried out analytically by varying the degradation level of the channel and the traffic load offered to the earth stations, taking High Amplitude Platforms (HAPs) as technological reference.
