Abstract: Methods and apparatus for delivering ordered and duplicate-free wireless data frames are generally described and claimed herein. Other embodiments may also be described herein. In an embodiment, a source address, a destination address, and a message sequence number are acquired from a wireless data frame. The message sequence number is compared against a last-received message sequence number and a last-delivered message sequence number. The destination address is also compared to a current address. In response to the compares, a decision is made to forward the wireless data frame to the destination address, discard the wireless frame as a duplicate wireless data frame, queue the wireless data frame, or release the wireless data frame to a next protocol layer.

Abstract: Network node power management methods and apparatus are generally described herein. Other embodiments may be described and claimed.

Abstract: A media access control layer of a wireless mesh network router includes a rate monitor to compare a packet transmission rate with a packet reception rate, and a rate adjustment request generator to generate a rate adjustment request message for one or more upstream neighbor nodes after the packet reception rate exceeds the packet transmission rate.

Abstract: A media access controller (MAC) for wireless mesh networks comprises a quality-of-service (QoS) manager to monitor consumed bandwidth of a current application flow and to compare the consumed bandwidth with a contracted bandwidth for the current application flow. The MAC also comprises a contention manager to coordinate access to a wireless communication channel for communications with other nodes of the wireless mesh network. The QoS manager instructs the contention manager to employ signaling to request additional resources for the current application flow after the consumed bandwidth is significantly less than the contracted bandwidth.
