Abstract: A network of access points (AP) in a high-density environment may be provided. A number of packet transmission retries for one or more of the AP may be determined by setting a number, m, of retries for transmitting a data packet, where m is the upper limit of the number of retries. Data packets are then transmitted m times. Upon transmitting the data packet m times, a success probability SP(u,m) for transmission of the data packet, where u is the number of users, may be calculated. The transmission of the data packet may be repeated m−x times where x is an integer. Upon calculating the success probability for m−x times, a success probability SP(u,m−x) for transmission of the data packet may be calculated. If SP (u,m−x) is larger than SP(u,m) then x may be decreased by one and actions (b)-(f) may be repeated. If SP (u,m−x) is not larger than SP(u,m) then m−x may be set as the maximum number of retries for the data packet.

Abstract: Application-based Transmission Opportunity (TXOP) sharing may be provided. First, a sharing AP may receive a request to share TXOPs with a requesting AP. The request may include information associated with an application executing on a client serviced by the requesting AP. Next, a TXOP duration for the requesting AP may be reserved based on the information associated with the application such that, in response to winning contention on the medium, the sharing AP may share a TXOP with the requesting AP for the TXOP duration.

Abstract: Access Point ranging and placement on a floorplan may be provided. A host AP may range each neighbor AP of the host AP. One or more neighbor APs that failed ranging with the host AP may be categorized in a failed neighbor AP list. The host AP may re-range each of the one or more neighbor APs in the failed neighbor AP list with a modified ranging parameter. At least one neighbor AP of the one or more neighbor APs may be categorized in the failed neighbor AP list that succeeded in re-ranging with the host AP in an extended range neighbor AP list.
