  • Patent number: 8351451
    Abstract: An embodiment of the invention involves a method for selecting and maintaining wireless communications for wireless mesh networks between tier-2 and tier-3 nodes. The method comprises a first operation of receiving channel information from a first wireless node operating as an access point. The channel information includes each channel number used by one or more wireless nodes that are detected by the first wireless node to be operating within a signal coverage area of the first wireless node. Then, an active scan is conducted on a frequency spectrum for wireless signals based on the channel information. Such scanning is accomplished by initially scanning frequencies of each channel number used by the one or more wireless nodes. After the scanning, a determination is made whether to (i) maintain wireless communications with the first wireless node or (ii) establish new wireless communications with a new wireless node (AP). Other embodiments are described and claimed.

  • Patent number: 8345609
    Abstract: An embodiment of the invention involves a method for selecting an infrastructure mode wireless channel for a tier-2 wireless node of a plurality of wireless nodes forming a wireless mesh network. The method comprises a first operation of receiving information from at least one neighboring node. Then, the first wireless node determines if a collision has occurred with the at least one neighboring node, where the collision is an overlapping of wireless channels selected by the first node and the at least one neighboring node. If a collision has occurred, the first wireless node compares its network degree, iterative count, and MAC address (progressively in that order) with that of its neighboring node to determine which of the first wireless node or the at least one neighboring node is responsible for re-selecting a different wireless channel from a set of non-overlapping wireless channels that are available to the wireless mesh network. Other embodiments are described and claimed.

  • Patent number: 8300578
    Abstract: According to one embodiment of the invention, a method for managing seamless roaming of a wireless node of a plurality of nodes forming a wireless network comprises detecting, recovering and transmitting operations. The detecting operation involves detecting receipt of a Disassociation message from the wireless node by a first node of the plurality of nodes. The wireless node is roaming and seeking to establish a new communication with a second node of the plurality of nodes. The recovering operation involves addressing information from the Disassociation message by the first node, where the addressing information identifies the second node of the plurality of nodes. The transmitting operation involves transmitting a Route Update message to at least the second node of the plurality of nodes. Other embodiments are described and claimed.

  • Patent number: 8223786
    Abstract: An embodiment is a technique to perform packet scheduling for QoS. A plurality of buffers is visited in a variable round robin manner. The buffers store packets having packet types associated with priority levels and having buffer types according to the packet types. The packets are generated for transmission from an application according to a network protocol in a multi-hop mesh network having a local node and a remote node. The buffers are dequeued according to the buffer types and using an amount dynamically weighted by the priority levels associated with the buffer types.

  • Patent number: 8130704
    Abstract: An apparatus and method for a multi-tier wireless home mesh network is described. The method may include formation of an infrastructure-less wireless home mesh networking environment comprising a collection of nodes that operate as a decentralized, ad hoc wireless network with multiple sub-networks or tiers that are responsible for different functions within the network. Each node of the multi-tier network is configured to forward data to other nodes and is assigned to a particular tier based on the node's performance capabilities. A further embodiment includes identification of a wireless home mesh network. Once identified, one or more proprietary messages may be exchanged in a secure manner to establish connections with a home electronics device as either a mobile node or a stationary node of the home network. A home electronics device may wirelessly communicate to route data within one or more nodes of the wireless home mesh network. Other embodiments are described and claimed.
