Packet Transmission Scheduling for Enhancing Power Saving and TCP Throughput Performance in Wireless LAN with Multicast/Unicast Flows
Yosuke Tanigawa, Yuta Umeno, Hideki Tode · 2018
In recent wireless LANs, multicast transmission is increasing in addition to unicast that is transferred mainly based on TCP. On the other hand, because mobile and wearable computers have been diffused widely, power saving of wireless stations becomes more important. In this paper, in general environments where multicast and unicast flows coexist, we propose a new transmission method of both multicast and unicast packets, that assigns sufficient transmission opportunities for unicast TCP flows, while achieving power saving performance for wireless stations receiving multicast flows.
