Abstract: The broadcast nature of wireless communication may be utilized by transmitting a packet frame identifying at least one relay node that can transmit the packet frame without transmitting an acknowledgement frame confirming receipt of the packet frame by a respective relay node. A relay node may cancel a relay obligation to transmit a packet frame based on detecting transmission of the packet frame by another node or based on detection of an acknowledgement frame confirming that a destination node received the packet frame. A transmission chain corresponding to the transmission of a packet frame may be assigned a priority. Alternatively or in addition, a relay node within a transmission chain may be assigned a priority. A priority may determine the amount of delay inserted prior to transmitting a packet frame.

Abstract: A technique involves untethered access points (UAPs) that can broadcast estimated transmission time (ETT) that represents an estimated time it would take for a packet to be transmitted from the first UAP to an AP that is wire coupled to a network. The proposed system can offer, among other advantages, accurate ETT values for use by UAPs of a wireless network.

Abstract: A technique for implementing an untethered access point (UAP) mesh involves enabling AP-local switching at one or more UAPs of the mesh. A system constructed according to the technique may include a wireless switch; an access point (AP) wire-coupled to the wireless switch; and a UAP mesh, wirelessly coupled to the AP, including a UAP with an AP-local switching engine embodied in a computer-readable medium. Another system constructed according to the technique may include an untethered access point (UAP), including: a radio; a backhaul service set identifier (SSID) stored in a computer-readable medium; an anchor access point (AAP) selection engine embodied in a computer-readable medium. In operation, the AAP selection engine may use the radio to attempt to associate with the AAP if a beaconed backhaul SSID matches the stored backhaul SSID.

Abstract: A technique for buffering multicast messages in an access point (AP) relates to buffering multicast messages in an AP when a client of the AP is in powersave mode. Attributes of clients are used to group the clients into subsets, so multicast messages only need to be buffered if one of the clients in the subset in which an intended recipient is a member is in powersave mode. The buffered multicast message may then be sent at a later time when intended recipients are not in powersave mode.
