| Summary |
In this paper, we propose two dynamic bandwidth
allocation (DBA) schemes, a game theory based DBA and a
successive DBA, for satellite/terrestrial integrated mobile communication
system (STICS). The game theory based DBA allocate
the bandwidth according to a utility function based on a weighted
demand bandwidth of both satellite and terrestrial system.
The successive DBA recursively allocates an unit of bandwidth
according to a weighted number of bandwidth unfilled cells of
both satellite and terrestrial systems, until the total bandwidth is
fulfilled. As results, both DBA outperform the conventional fixed
bandwidth allocation scheme. Between two proposed DBA, the
successive DBA shows better spectral improvement ratio than
the game theory based DBA. |
