A distributed spatial reuse (DSR) MAC protocol for IEEE 802.11 ad-hoc wireless LANs

The paper proposes a distributed spatial reuse (DSR) MAC protocol for IEEE 802.11 ad-hoc wireless LANs (WLANs) to increase bandwidth utilization and reduce power consumption. Through power control, the communications that do not interfere with each other can transmit simultaneously. Therefore, the overall efficiency and effectiveness of IEEE 802.11 ad-hoc WLANs can be enhanced. DSR allows the maximum number of interference-free communication pairs to transmit in parallel without collisions. According to the experiment results, DSR is much better than traditional WLAN protocol, IEEE 802.11 DCF, and the related work. The protocol indeed can effectively enhance the overall WLANs efficiency.
