A performance of multi-channel poling/CSMA protocols for wireless multi-hop networks

摘要

In this paper, we propose a new multi-channel Polling/CSMA protocols for wireless multi-hop networks and evaluate its performance by computer simulation. As proposed protocol changes its access method by traffic variance autonomously, proposed protocol is suitable for multi-hop wireless networks where traffic is inclined, and can guarantee QoS from End-to End. Computer simulation shows that proposed MAC protocol improves a throughput by about 60% compared to the conventional DCF, and lower delay and blocking rate are achieved.
