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: Techniques for distributed computation are provided. A plurality of edge computing devices available to execute a computing task for a client device is identified, and a first latency of transmitting data among the plurality of edge computing devices is determined. A second latency of transmitting data from the client device to the plurality of edge computing devices is determined, and a set of edge computing devices, from the plurality of edge computing devices, is determined to execute the computing task based at least in part on the first and second latencies. Execution of the computing task is facilitated using the set of edge computing devices, where the client device transmits a portion of the computing task directly to each edge computing device of the set of edge computing devices.

Abstract: Techniques for identifying an orientation for an antenna in a wireless communication device. A plurality of estimates of antenna gain are determined for an antenna associated with a wireless access point (AP), the plurality of estimates of antenna gain relating to a plurality of wireless stations (STAs) associated with the AP. An orientation for the antenna is determined based on the plurality of estimates of antenna gain and a plurality of properties for the antenna.
