摘要： Systems and methods are provided for improving efficiency and reliability of broadcast transmission in a multi-hop wireless mesh communication network. When an intelligent access point (IAP) receives a broadcast packet (BP), the IAP can determine a list of downlink child mesh nodes (DLCMNs) of the IAP based on route information provided in its routing table. After the IAP knows its DLCMNs, the IAP can determine a first lowest data rate (LDR) between the IAP and each of its DLCMNs, and then re-transmit the BP at the first LDR. The BP is then received by at least one “parent” mesh node, which can then perform similar processing, and can then re-transmit the BP to its DLCMNs. This process repeats until the BP reaches a leaf mesh node. In other words, each mesh node can determine its DLCMNs, determine the LDR between itself and each of its DLCMNs, and can then re-transmit the BP at this LDR.

摘要： A dynamic and distributive aggregation method in which a node determines the frame size of an aggregated frame based on or according to a transmission time of one or more of the received frames. This scheme to aggregate frames is based on the average packet size and average transmission time in the neighborhood. The method enables the aggregated packet size to dynamically change based on the neighborhood conditions. Usage of link rates and fair transmission time assignment enables the high data rate nodes to send more traffic but not to an extent of over-utilizing the channel thus achieving higher throughput efficiencies while maintaining fairness within a high data rate multi-hop wireless communication network.
摘要翻译：一种动态和分布式聚合方法，其中节点基于或根据所接收的一个或多个帧的传输时间来确定聚合帧的帧大小。这种聚合帧的方案是基于邻域的平均分组大小和平均传输时间。该方法使聚合的分组大小能够根据邻域条件动态地改变。链路速率和公平传输时间分配的使用使得高数据速率节点能够发送更多的业务，而不是在一定程度上过度利用信道，从而实现更高的吞吐量效率，同时保持在高数据速率的多跳无线通信网络内的公平性。
