A receiver in a congestion state sets a duration field value of congestion control in a CTS frame and transmits the CTS frame to a sender. In response, the sender retransmits an RTS frame to the receiver without transmitting data, after waiting for an RTS retransmission waiting time period corresponding to the duration field value. The congestion state information is broadcast to neighboring nodes. Therefore, the congestion control system using the CTS frame does not use a separate frame for the congestion control. And, all of the neighboring nodes can participate in the congestion control, increasing the network efficiency.

  • Patent number: 9497743
    Abstract: A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. Currently active CPEs request bandwidth using unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE.

At least one slave node is an implantable device. Master nodes initiate all data exchange sequences, and slave nodes are responsive to the data exchange sequences. The exchange sequences begin by master nodes contending for use of the carrier through a countdown procedure. A set order of communications occurs between a master node who won the contention and a slave node being communicated with by the master node to transfer a data frame. Contention is then repeated to determine the next master node that is allowed to transfer a data frame. New master nodes entering the network employ a discovery process to poll for existing devices in the network.

  • Patent number: 8989213
    Abstract: Certain aspects of the present disclosure provide methods and apparatus for utilizing a physical layer (PHY) header comprising an identifier for an access point (AP) or a Basic Service Set (BSS). A station (STA) that is assigned an order in a sequential response sequence may count only frames with PHY headers that contain the correct identifier. A STA may terminate its sequential access procedure when it receives a frame with a PHY header that specifies a different identifier for the AP or BSS that assigned the sequence. In this manner, the STA may prevent partly synchronizing to an overlapping network and avoid accessing the wireless medium at the wrong time.

  • Patent number: 8902821
    Abstract: Disclosed are a method and system for an intermediate node, which negotiates a Quality of Service (QoS) contract with two or more secondary nodes, to maintain a record of previous contract agreements to use as the basis for future contracts and to select the negotiation order with the secondary nodes based on a configurable rule set. The intermediate node selects the secondary node which is deemed to be (predicted as) most restrictive to begin QoS negotiations. The intermediate node dynamically creates for a specific user a new QoS profile to begin the QoS negotiations based on current system loading and historical QoS precedents.

  • Patent number: 8891456
    Abstract: Access control based on CSMA is favorably carried out with the RTS/CTS method used together. If the RTS/CTS procedure is used together, CTS information is transmitted in response to the reception of RTS information, and data is transmitted in response to the reception of CTS. The CTS transmitting station measures the quality of RTS receive signal, and thereby determines a transmission rate at which it can receive and notifies a station as the destination of CTS. The station as the destination of CTS transmits data in response to CTS information. As the transmission rate for this data, the transmission rate indicated in the RATE field in CTS is applied.
