L. Wu et Pk. Varshney, Performance analysis of CSMA and BTMA protocols in multihop networks (II).Multiple channel case, INF SCI, 120(1-4), 1999, pp. 179-195
Busy tone multiple access protocols have been used in multihop networks to
reduce the effect of the hidden terminal problem. This paper demonstrates a
nother approach to reduce the effect of the hidden terminal problem namely
the use of multiple channel schemes. A protocol that uses both the busy ton
e and the multiple channel techniques achieves the best performance. Using
a Markov chain model and an approximation, the throughput performance of th
e multiple channel non-persistent CSMA protocol and the multiple channel co
nservative BTMA protocol in a large network is evaluated and compared. The
results show that the multichannel CSMA and BTMA schemes exhibit a better p
erformance over their single channel counterparts in a multihop network. (C
