摘要： In one embodiment, a device connected to a network receives at a network interface a first network size indicator for a first network and a second network size indicator for a second network. A difference between the first network size indicator and the second network size indicator is determined and a switching probability is calculated if the difference between the network size indicators is greater than a predetermined network size difference threshold. The device may then migrate from the first network to the second network based on the switching probability.

摘要： In one embodiment, a device may select, based on an optimal tone map, a particular subcarrier for use when transmitting a data frame, the data frame to serve as a tone map request (TMREQ). The device may then populate one or more unused quality subcarriers of the TMREQ data frame other than the particular subcarrier with a well-known bit sequence, and transmits the TMREQ data frame to a receiving device to cause the receiving device to evaluate transmission quality of the one or more unused quality subcarriers based on the well-known bit sequence.

摘要： In one embodiment, a device maintains a predetermined number of high-priority subcarriers for use in communicating high-priority data frames and a predetermined number of low-priority subcarriers for use in communicating low-priority data frames. A data frame is received and a data frame priority is determined for the data frame. If the data frame is determined to be a low-priority data frame, a minimum number of subcarriers, from the low-priority subcarriers, required for communication of the data frame is determined and the data frame is communicated using the minimum number of subcarriers. If the data frame is determined to be a high-priority data frame, a maximum number of subcarriers available, including the high-priority subcarriers and the low-priority subcarriers, is determined and the data frame is communicated using the maximum number of subcarriers.

摘要： According to one embodiment, techniques are provided to enable secure communication among devices in a mesh network using a group temporal key. An authenticator device associated with a mesh network stores a pairwise master key for each of a plurality of devices in a mesh network upon authentication of the respective devices. Using the pairwise master key, the authenticator device initiates a handshake procedure with a particular device in the mesh network to mutually derive a pairwise temporal key from the pairwise master key. The authenticator device encrypts and signs a group temporal key using the pairwise temporal key for the particular device and sends the group temporal key encrypted and signed with the pairwise temporal key to the particular device.
