摘要： A hybrid TDMA-CSMA MAC protocol is provided for allocating time slots within a frame having a structure in which transmission time is divided into a first number of actual TDMA time slots and a second number of “virtual” CSMA time slots. Each of the nodes in a multi-hop network can transmit a Highest Slot Number (HSN) field. Each time one of the Hello messages is received from a neighbor node, a given node can calculate variables based on the HSN field. The given node can use these variables to calculate a ratio of the first number to the second number. This ratio can be dynamically adjusted depending upon the traffic conditions observed by nodes within the multi-hop ad hoc network at any particular time to thereby change the relative percentages of the frame which are allocated for a TDMA portion and a CSMA portion of the frame.
摘要翻译：提供了一种混合TDMA-CSMA MAC协议，用于在具有传输时间被划分为第一数量的实际TDMA时隙和第二数量的“虚拟”CSMA时隙的结构的帧内分配时隙。多跳网络中的每个节点可以发送最高时隙号（HSN）字段。每当从邻居节点接收到一个Hello消息时，给定节点可以基于HSN字段计算变量。给定节点可以使用这些变量来计算第一个数字与第二个数字的比率。该比率可以根据在任何特定时间的多跳自组织网络内的节点观察到的业务条件来动态地调整，从而改变为TDMA部分分配的帧和帧的CSMA部分的相对百分比。

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。

摘要： A system and method for improving a current wireless communication route, between a source node and a destination node in an on-demand wireless communication network, enables the current communication route to be improved even when the current route has not failed. The method includes analyzing at a local node a packet transmission from the source node, the packet transmission comprising a current route metric (step 705). The local node then determines that it can provide an improved wireless communication route, between the source node and the destination node, having a better route metric than the current route metric (step 710). A route improvement message is then transmitted from the local node to the source node (step 740).

摘要： A system and method that creates an abstraction of the physical layer of a wireless communication network (100), in particular, a wireless ad-hoc peer-to-peer communication network (100), and that normalizes the feedback from the physical layer to enable multiple types of nodes (102, 106, 107) in the wireless network to operate using a common wireless routing protocol. This routing protocol uses a link quality metric to determine the best route regardless of how it actually chooses the route or disseminates such link quality information. The generalized routing metric can be derived for any node (102, 106, 107), regardless of its relative performance or its media access control (MAC) technology. The system and method also create a transaction summary that can be used for link adaptation and link quality estimation to determine, for example, future data rates, link quality/routing metrics, and transmit powers.
