A Real Time Algorithm for Bandwidth and Time-slot Assignment for Rain Faded DVB-RCS Systems

Broadband satellite communication networks, operating at Ka band and above, play a vital role in today’s worldwide telecommunication infrastructure. The problem, however, is that rain can be the most dominant impairment factor for radio propagation at these frequencies. This paper, addresses bandwidth and time-slot allocation problem for rain faded DVBRCS satellite networks. We formulate the task as a combinatorial optimization problem and propose a novel algorithm for dynamic bandwidth and time allocation, which works with CRA type of traffic. The algorithm is evaluated using a MATLAB simulation with historical rain data for the UK.
