An efficient technique for dynamically allocating channels in satellite cellular networks

This paper proposes an improved technique for dynamically allocating channels in mobile satellite cellular networks. Channel assignment on demand is performed on the basis of the evaluation of a cost-function. When the cell of a new call arrival does not have available channels, a single channel reconfiguration in an interfering cell is attempted in order to accept a new call. Handover requests that do not receive immediate service can be queued for a maximum time. The scenario envisaged is low Earth orbit-mobile satellite systems (LEO-MSSs). A performance comparison with other dynamic channel allocations has been carried out in order to highlight the higher efficiency of the dynamic technique proposed.
