  • Adaptive medium access control
    Patent number: 8675678
    Abstract: Bandwidth allocation configuration and fully decentralized adaptive medium access control (AMAC) systems and methods with support for time critical applications, spectrum efficiency, scalability enhancements, and fair allocation of bandwidth among nodes sharing a common channel. The methods fully integrate TDMA and CSMA/CA channel access approaches and incorporate adaptive congestion and collisions avoidance scheme to reduce bandwidth wastage and diminish adverse cross layers interactions.
    Type: Grant
    Filed: September 12, 2011
    Date of Patent: March 18, 2014
    Assignee: The Johns Hopkins University
    Inventors: Osama I. Farrag, William P. D'Amico

  • Decentralized media access control for ad-hoc mobile wireless network
    Patent number: 7881340
    Abstract: A method of operating a decentralized ad-hoc wireless network including wireless stations, comprises establishing a common time reference which is used by the wireless stations to share access to a common wireless channel, the common time reference having a periodic superframe structure including a Scheduled Beacon Period, a Contended Beacon Period, Contention Periods (CPs) and Contention Free Periods (CFPs). The method further comprises time-scheduling, using wireless communication between the wireless stations, the CFPs in the SBTT interval to at least some of the wireless stations requesting access to the CFPs, and granting access to the CPs to at least some of the wireless stations requesting access to the CPs.
