An accumulative acknowledgment protocol for point-to-multipoint high speed communications

This paper proposes and analyses the performance of a finite buffer point-to-multipoint selective repeat (SR) protocol with accumulative acknowledgment. The proposed strategy is based on three key ideas. The first is the use of accumulative acknowledgments in order to reduce the required processing overhead and implementation complexity. The second and third aim at improving the throughput efficiency: to make the most of the selective repeat recovery procedure and to process and store all messages correctly received during an exception condition. The proposed strategy performs very well under a wide range of conditions, being more efficient than all known point-to-multipoint GB(N) strategies, for low bit error rates
