Abstract: A distributed and opportunistic medium access control (MAC) layer protocol for randomized distributed space-time coding (R-DSTC), which may be deployed in an IEEE 802.11 wireless local area network (WLAN), is described. Unlike other cooperative MAC designs, there is no need to predetermine, before packet transmission, which stations will serve as relays. Instead, the MAC layer protocol opportunistically recruits relay stations on the fly. Network capacity and delay performance is much better than legacy IEEE 802.11g network, and even cooperative forwarding using one relay station. Avoiding the need to collect the station-to-station channel statistics considerably reduces overhead otherwise required for channel measurement and signaling.

Abstract translation: 描述了可以部署在IEEE 802.11无线局域网（WLAN）中的用于随机分布时空编码（R-DSTC）的分布式和机会性介质访问控制（MAC）层协议。 与其他合作MAC设计不同，在分组传输之前，不需要预先确定哪些站将用作中继站。 相反，MAC层协议机会地即时招募中继站。 网络容量和延迟性能远优于传统IEEE 802.11g网络，甚至使用一个中继站进行协作转发。 避免收集站对站信道统计的需要大大减少了信道测量和信令所需的开销。

Abstract: When it is advantageous to do so, a wireless LAN station sends data packets to a destination station via an intermediate station, instead of to the destination station directly. That is, the intermediate station, which serves as a helper to the source, forwards packets received from the source station to the intended destination station. This cooperative data transmission approach can result in system performance improvement, as long as the total time consumed by two-hop transmission (i.e., transmission via the helper station) is less than direct transmission. Such a determination may be made using rate information stored at each station. Specifically, using the rate information, signaling needed to set up a transmission, the amount of data to be transmitted, etc., transmitting the data directly and via a help station may be compared.

Abstract translation: 当这样做有利时，无线LAN站经由中间站将数据分组发送到目的站，而不是直接发送到目的站。 也就是说，作为来源的帮助者的中间站将从源站接收的分组转发到预定的目的地站。 只要通过两跳传输（即经由辅助站的传输）消耗的总时间小于直接传输，该协作数据传输方法可以导致系统性能改善。 可以使用存储在每个站处的速率信息来进行这样的确定。 具体地，可以比较速率信息，建立传输所需的信令，要发送的数据量等，直接和经由帮助台发送数据。

Abstract: A method and a coordinator of superframe management are disclosed. The method includes receiving, by a coordinator, a GTS request from a node; determining the type of the node; allocating GTS in an active period based on GTS characteristics carried in the GTS request when the node is determined as an energy restricted device; allocating GTS in an active period and an inactive period based on GTS characteristics carried in the GTS request when the node is determined as an energy unrestricted device. As can be seen from the method of the present invention, for an energy unrestricted device, allocated GTS may extend to an inactive period. Since the length of slots allocated to the energy unrestricted node is extended, the QoS of the energy unrestricted node is improved and guaranteed. Meanwhile, since the method of the present invention considers and makes full use of the inactive period in the superframe, the network throughput is improved significantly.
