摘要： Embodiments of methods of assigning a channel to a link of an access node within a wireless mesh network, is disclosed. The method includes the access node receiving beacons over multiple channels, from at least one upstream device, and the access node selecting an uplink channel based upon the received beacons. Additional methods include the access node selecting a downlink channel so that different channels are assigned to consecutive links within a data path between a gateway and a down stream device. The different channels can include non-overlapping channels, or a combination of non-overlapping and at least partially overlapping channels. The method can further include selecting a downstream link channel based upon predetermined sequences of channel selections, and a hop count of the access node.

摘要： A method of adaptively setting a transmission power level of a node within a wireless mesh network is disclosed. The method includes monitoring a quality of a plurality of reverse direction links between the node and downstream nodes, and between the node and an upstream node, of the wireless mesh network. At least one worst quality reverse direction link is identified. If the at least one worst quality link is greater than a high threshold, then the transmission power level of the node is decreased. If the at least one worst quality link is less than a low threshold, then the transmission power level of the node is increased. A method of adaptively selecting transmission power of gateway nodes of a wireless mesh network is also disclosed. The method includes each gateway node monitoring a quality of a plurality of reverse direction links between the gateway node and downstream nodes of the wireless mesh network. Each gateway node identifies at least one worst quality reverse direction link. For each gateway node, if the at least one worst quality link is greater than a high threshold, then decreasing the transmission power level of the gateway node is decreased. For each gateway node, if the at least one worst quality link is less than a low threshold, then the transmission power level of the gateway node is increased.

摘要： 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.

摘要： A method of verifying a mesh network is disclosed. The method includes identifying wireless links from a set of selected mesh network routing links, that have a link quality below a predetermined quality threshold, and providing a network manager with a link list that lists and prioritizes the identified wireless links according to a degree of impact each identified wireless link has on performance of the mesh network. Determining the degree of impact of each identified wireless link can include determining an amount the mesh network relies upon identified wireless link. Mesh network reliance can be dependent on how many routes through the mesh network include the identified wireless link. Determining the degree of impact of each identified wireless link can include determining a link quality of the identified wireless link.
