    • In one embodiment, in absence of transmitting from an apparatus a reservation request frame, the apparatus receives a reservation response frame on an assigned channel. The reservation response frame indicates a duration of a frame transmission. In response to receiving the reservation response frame, the apparatus transmits a frame on the assigned channel during the frame transmission. In another embodiment, in response to receiving a reservation request frame on a first channel at an apparatus, the apparatus transmits a reservation response frame on the first channel and on at least one second channel. The reservation request frame indicates a duration of a frame transmission. The reservation response frame indicates the duration of the frame transmission. After transmitting the reservation response frame, this apparatus receives during the frame transmission a first frame on the primary channel and a second frame on the at least one secondary channel.
    • 在一个实施例中,在没有从装置发送预留请求帧的情况下,装置在分配的信道上接收预留响应帧。 预约响应帧指示帧传输的持续时间。 响应于接收到预约响应帧,该装置在帧传输期间在所分配的信道上发送一帧。 在另一个实施例中,响应于在设备处的第一信道上接收到预留请求帧,该设备在第一信道上和至少一个第二信道上发送预留响应帧。 预留请求帧指示帧传输的持续时间。 预约响应帧指示帧传输的持续时间。 在发送预留响应帧之后,该装置在帧传输期间接收主信道上的第一帧和至少一个次信道上的第二帧。

    • Various embodiments are described relating to selecting anchor nodes among nodes in a wireless network. In an example embodiment, a topological arrangement of a first wireless node and one or more other wireless nodes neighboring to the first wireless node in a wireless network may be determined by the first wireless node. A second wireless node may be selected to perform anchor node operations for the first wireless node based on the determined topological arrangement. For example, the first wireless node may select itself to perform the anchor node operations based on the determined topological arrangement.

    • 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.
    • 公开了方法,装置和计算机程序产品实施例,以通过限制对等网格站接收的组寻址帧的源的数量来改善无线网状网络中的功率节省和效率。 在本发明的示例性实施例中,门户无线对等网格设备在无线网状网络中发送门户通告帧,以创建从网络内的无线网状设备到门户的单向路径。 门户公告框架从一个无线对等网格设备转发到另一个网络,以洪泛网络。 接收Portal通知帧的每个无线对等网格设备接收门户的网络地址和将帧发送到接收发送设备的无线对等网格设备的网络地址。 接收设备可能已经从多个发送设备接收到多个门户通知帧。 首先,接收无线网状设备选择多个发送无线网状设备中的第二个发送无线网状设备作为唯一发送源,第一接收无线网状设备将从该发送源接收组寻址消息。 第一无线网状设备向第二无线对等网格设备发送组传递通知消息,通知第二设备将其选择作为用于第一设备的组寻址消息的唯一发送源。 此后,第一无线网状设备仅从第二无线对等网格设备接收组寻址消息。
