摘要： A method of hybrid route discovery in a mesh network is described. The method comprises the optional designation of a root node of the mesh network and formatting a route request message at an originating mesh point, where the route request messages include a hop limit parameter. If a root node has been configured, the route request is responded to with a message that describes the route to the root. If a direct route between two nodes is required, the route request message is broadcast from the originating mesh point, and the hop limit parameter limits the number of times the route request message will be forwarded. The originating mesh point receives a unicast route reply message from a neighboring mesh point, after the neighboring mesh point received the route request message. Finally, a route connecting the originating mesh point and the destination mesh point is established.
摘要翻译：描述了网状网络中混合路由发现的方法。该方法包括可选地指定网状网络的根节点，并且在发起网格点格式化路由请求消息，其中路由请求消息包括跳数限制参数。如果已经配置了根节点，则路由请求将使用描述到根路由的消息进行响应。如果需要两个节点之间的直连路由，则从始发网点广播路由请求消息，并且跳数限制参数限制路由请求消息将被转发的次数。在相邻网格点接收到路由请求消息之后，始发网格点从相邻网格点接收单播路由应答消息。最后，建立连接起始网格点和目的网格点的路由。

摘要： Methods, apparatuses and systems directed to a border access point protocol that facilitates network selection and mobility operations for wireless clients, such as dual-mode wireless telephones and other devices. In one implementation, the present invention provides a wireless network infrastructure comprising a plurality of access points, at least some of which are so-called border access points that provide border information to wireless clients. The border information, in one embodiment, indicates to the wireless client that the transmitting access point is proximal to the perimeter of the intended coverage area of the wireless network infrastructure. In another implementation, the border information indicates that the transmitting access point is proximal to a point of egress from, or ingress to, a coverage area. Wireless clients within range of the border access points can use the border information to facilitate or enhance selection of a network for initiation of a given section, as well as in handoff or other mobility operations between two network types or domains (e.g., a WLAN and a cellular network).

摘要： In a wireless Local Area Network (WLAN) system, a hierarchical architecture is provided which employs a protocol which divides protocol processing functions between a plurality of substantially identical access elements in which reside time-critical protocol functions, such as acknowledgment and retransmission of packets, and a centralized control element which provides control and management functions related to dynamic configuration of wireless networks, such as processing of network management messages (e.g., authentication and association), load control, channel control, and handoff, processing of physical layer information, and processing of channel characteristics, propagation, interference or noise, for the plurality of access elements on the WLAN without loss of information about the wireless characteristics of the access elements. This hierarchical protocol processing architecture allows the data flow to be centralized for better performance and provides useful access to all the protocol information from the WLAN.

摘要： Methods, apparatuses, and systems directed to a key distribution and caching mechanism that facilitates roaming in wireless networks. In one implementation, the present invention reduces the latency associated with handoffs by reducing the time required to set up encryption or other secure access mechanisms between access points and clients in the wireless network infrastructure. In one implementation, the present invention operates proactively to distribute authentication credential information to selected components of the wireless network infrastructure before a client roams to another access point.

摘要： The present invention discloses the use of wear measuring elements to monitor the wear of cleaning elements on cleaning devices, such as cleaning machines and vacuum cleaners. The wear measuring elements are located adjacent to cleaning elements and have a length corresponding to a minimum desired length for the cleaning elements. When the length of the cleaning elements decreases due to usage to the length of the wear measuring elements, the user will realize that the cleaning elements need replacement.
