  • Apparatus and method for detecting and alleviating unfairness in wireless network
    Patent number: 10075965
    Abstract: A network relaying device facilitates communication among a plurality of network nodes. When the network relaying device receives a data packet from a first network node, it determines whether a historical transmission rate of the first network node exceeds a threshold rate. Based on this determination, the network relaying device determines whether to associate the data packet with a first queue or a second queue for transmission to a second network node.

  • Apparatus and method for communication path recovery with adaptive channel bandwidth in wireless mesh network
    Patent number: 9942826
    Abstract: A mesh network relaying device includes at least a first radio, a second radio, and a third radio. During normal operation, the device communicates with other network nodes via the first and second radios, the radios operating at the best available bandwidth. When the device identifies a communication link failure in one of the first and second radios, the device activates the third radio and operates the first, second, and/or third radios at narrower bandwidths. When the communication link failure is resolved, the device deactivates the third radio, and resumes communication via the first and second radios at wider bandwidth.
