摘要:
A method of optimizing link transmission parameters between access nodes within a mesh network is disclosed. The method includes each access node within the mesh transmitting packets at N different combinations of data rates and power levels. Each receiving node that receives the data packets at one or more of the N combinations, selects a most desirable one of the received combinations. The receiving nodes indicate to the transmitting nodes the selected most desired combination for transmitting to the receiving node.

An apparatus and method of a mobile node selecting a transmission channel of a mesh network is disclosed. The method includes the mobile node detecting a quality of routing beacons received over a previously selected transmission channel. If the quality of the routing beacons is below a predetermined threshold, then the mobile node transmits probe requests on each of a plurality of available transmission channels. Responses to the probe request are collected from at least one upstream access nodes over at least one of the available transmission channels. A new transmission channel is selected based upon the responses received over the available transmission channels.

An apparatus and method of a gateway selecting transmission channels of a cluster of a wireless mesh network is disclosed. The cluster includes the gateway and a plurality of access nodes. The method includes the gateway cycling through a plurality of available transmission channels, evaluating channel each of the available transmission channels, and selecting a cluster transmission channel based on the channel evaluations. An apparatus and method of a node within a wireless mesh network selecting a transmission channel is also disclosed. The method includes the node cycling through a plurality of available transmission channels, measuring a persistence of successfully received routing packets from upstream devices at each of the available transmission channels, evaluating noise of each of the available transmission channels, and selecting one of the available transmission channels based on the persistence of successfully received routing packets and the noise.
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.

A methods and apparatuses of adaptively capping data throughput of client devices associated with a wireless network are disclosed. One method includes monitoring an air-time per bit efficiency of each client device associated with the wireless network. A data throughput cap for each client device is adaptively determined based on the air-time per bit efficiency of the client device.

An apparatus and method of identifying long links within a wireless network is disclosed. The method includes identifying long links within a wireless network. The method includes a first node estimating a link quality of a wireless link between the first node and a second node of the wireless network. The first node uni-casts packets to the second node. The first node monitors a packet acknowledgment success rate. The first node identifies the wireless link to be a long link if the link quality is above a link threshold, and the packet acknowledgment success rate is below an acknowledgment threshold.

摘要:
A method of characterizing transmission of a node of a wireless network is disclosed. The method includes determining a neighbor function based on how many neighboring nodes are affected by a neighbor function based on how many neighboring nodes are affected by signals transmitted from the node at varying power levels. For a range of transmission path losses between the node and neighboring nodes, transmission power levels and transmission data rates are calculated that minimize an air-time metric, wherein the air-time metric is dependent on the neighbor function and an air-time occupied by transmission packets.

A wireless access node includes a first radio operable to transmit/receive on one of at least N transmission channels. A second radio is operable to transmit/receive on another one of the at least N transmission channels. A first filter bank, of less than N filters, filters a first transmit/receive signal of the first radio. A second filter bank, of less than N filters, filters a second transmit/receive signal of the second radio. Generally, N is greater than 2.
