| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have presented a binary exponential backoff algorithm in which the contention window (CW) is doubled when the node detects the wireless channel busy or it detects the frame collision for non-persistent carrier sense multiple access (NP-CSMA). By the success priority and the distributed control of the binary exponential backoff algorithm, we achieve high network throughput without centralized control even if the number of active nodes is varying. Since the network throughput gradually increases with increasing the number of active nodes, the CWs get higher than we require. In this manuscript, we propose a new backoff algorithm in which the CW is kept when the node detects the channel busy and the CW is doubled when the node detects the frame collision. Monte Carlo simulations clarify that the proposed algorithm achieves higher network throughput when the number of active nodes is relatively low and the network throughput gradually decreases with increasing the number of active nodes. | |
