  • Patent number: 7031293
    Abstract: It is the object of this invention to provide a method of increasing the data throughput of a multi-hop wireless link. A method is provided which mitigates self-interference, without precluding the use of omni-directional transceivers. Distributed protocols for channel allocations in a multi-hop wireless communication system are described. These protocols result in channel allocations that increase the capacity utilization of the network and render the system robust to localized interferers and jammers.

  • Patent number: 7016328
    Abstract: An apparatus and method for allowing a client to access a wireless system is disclosed. The system includes at least a first wireless access node. The method includes the first wireless access node detecting a client seeking access to the system. The first wireless access node being able to wirelessly connect to a back bone network. Client information is obtained. The first wireless node provides the client a communication path to and from a destination. The communication path is able to include wired and wireless communication links. Routing of information through the communication path between the client and the destination is aided based upon detection of the client. The wireless connection between the first access node and the back bone network can include at least one wireless hop between the first access node and a third access node.

  • Patent number: 6965575
    Abstract: The invention includes an apparatus and method for determining an optimal route based upon path quality of routes to an access node of a wireless mesh network. The method includes receiving routing packets at the access node through at least one wireless route. Each routing packet includes route information that identifies the wireless route of the routing packet. A success ratio of a number of successfully received routing packets versus a number of transmitted routing packets is determined over a period of time T1, for each wireless route. The wireless route having a greatest success ratio is first selected, as are other wireless routes that have success ratios within a predetermined amount of the greatest success ratio.

  • Patent number: 6704301
    Abstract: A method and apparatus for generating connectivity is described. The method includes a server broadcasting a beacon including the server's address. The method further includes each client that receives the beacon rebroadcasting the beacon. The result is that each client receiving the beacon knows a way to reach the server.
