(English Abstract) |
Existing MAC protocols for wireless LANs employ CSMA/CA that avoids collisions by preserving the wireless medium exclusively within 2-hop network. This medium reservation obstructs neighboring nodes at both sides from concurrent transmission. This problem reduces medium utilization and overall throughput in Wireless LANs. In this work, we offer parallel data transfers using concurrent virtual channels over same physical channel by distributed transmit/receive synchronization. Each virtual channel is used by a transmitter/receiver pair and all virtual channels within 2-hop network utilize the medium and avoid inter virtual channel interference. This virtual channel based protocol eliminates the exclusive medium reservation and improves the performance in terms of latency and overall network throughput. |
