摘要： Method, apparatus, and computer program product embodiments are disclosed to improve power conservation and efficiency in wireless mesh networks, by limiting the number of sources of group addressed frames that a peer mesh station receives. In an example embodiment of the invention, a portal wireless peer mesh device transmits a Portal Announcement frame in a wireless mesh network to create unidirectional paths from wireless mesh devices within the network to the portal. The Portal Announcement frame is relayed from one wireless peer mesh device to another to flood the network. Each wireless peer mesh device that receives the Portal Announcement frame receives the network address of the portal and the network address of the wireless peer mesh device that transmitted the frame to the receiving transmitting device. The receiving device may have received a plurality of Portal Announcement frames from a plurality of transmitting devices. A first, receiving wireless mesh device selects a second, transmitting wireless mesh device of the plurality of transmitting wireless mesh devices to be the sole transmitting source from which the first receiving wireless mesh device will receive group addressed messages. The first wireless mesh device transmits a group delivery notify message to the second wireless peer mesh device informing of the second device of its selection as the sole transmitting source of group addressed messages for the first device. Thereafter, the first wireless mesh device receives only from the second wireless peer mesh device, group addressed messages.

摘要： Method, apparatus, and computer program product embodiments are disclosed to improve power conservation and efficiency in wireless mesh networks. An example embodiment of the invention receives at a wireless mesh device a plurality of messages from other wireless mesh devices in a wireless mesh network and determines from the messages if there is one or more wireless peer mesh device in the network that is in a power save mode. If there is no wireless peer mesh device in the network that is in a power save mode, then the example embodiment transmits group addressed frames in any order. If there is at least one wireless peer mesh device in the network that is in a power save mode, then the example embodiment arranges a transmission order of group addressed frames that have a source different from a designated wireless mesh device in the network followed by group addressed frames that have the designated wireless mesh device as a source. Then the example embodiment transmits the group addressed frames in the transmission order to at least one other wireless mesh device in the network, with the group addressed frames having the designated wireless mesh device as a source being transmitted last. The arrangement of the order of transmission enables other wireless mesh devices operating in power save mode in the network to cease listening for further group addressed frames following receipt of the group addressed frames having the designated wireless mesh device as a source. In this manner power conservation and efficiency are improved in wireless mesh networks.

摘要： Method, apparatus, and computer program product embodiments are disclosed to improve network performance for ad hoc network initiation. Example embodiments include a new operational sequence for wireless devices initiating the use of an ad hoc network. The example embodiments require appropriately enabled wireless devices to only respond to probe request frames from other similarly appropriately enabled wireless devices. In this manner, two devices may avoid the time consuming effort of combining two different ad hoc networks into a single ad hoc network so that the two devices can communicate.

摘要： Method, apparatus, and computer program product embodiments are disclosed to improve the channel switching in communication protocols, by simplifying transmission of only a single, acknowledged switching message to trigger off channel—or base channel switching after an initial off channel configuration and set-up of the direct link. The single message off channel switching indication in direct link is based on two specific timeout timers that serve as a basis for channel switching between the devices in TDLS direct link. An immediate fallback transition is provided to the base channel in the event that the communication in the off-channel does not succeed. The timeouts in the fallback procedure allow continuing the planned data transfer immediately in the base channel of the TDLS direct link if the switching to the off channel has not succeeded.
