Improving the efficiency of CSMA using reservations by interruptions
Chuan Heng Foh, Moshe Zukerman · 2002
This paper proposes a new carrier sense multiple access (CSMA) protocol, called CSMA with reservations by interruptions (CSMA/RI). This new protocol uses a novel approach to reserve capacity for multiple users. The performance of the new protocol is studied by simulations under realistic (long range dependent) traffic conditions and compared with CSMA/CD as well as with its work conserving G/D/1 queue. It is demonstrated that CSMA/RI always offers better performance than CSMA/CD and under certain realistic assumptions regarding packet size, the performance of CSMA/RI can be very close to that of its G/D/1 benchmark.
