摘要： An operation channel in a multi-hop network is determined. The network uses a set of channels, and one of the nodes is a network management node. The operation channel is selected in the network management node. Then, the network management node broadcasts a channel information packet including the operation channel using all channels. The channel information packet is received in each of other nodes, either directly from the network management node or from an intermediate node that received and rebroadcasted the channel information packet. Lastly, the operation channel in each node is set according to the channel information packet until the network is formed.

摘要： A method and system discovers a route in a wireless communications network including multiple nodes. A RREQ frame is broadcast by a first node. The RREQ frame is generated to discover a route. A second node receives the RREQ frame. The second node unicasts a PING frame to the first node to verify an integrity of a wireless communications channel between the first node and the second node. Then, the second node unicasts a RREP frame only if the integrity of the wireless channel is verified.

摘要： A method localizes a set of nodes in a wireless network that includes a target node having unknown location and a set of anchor nodes having known locations. The set of anchor nodes is partitioned into subsets of anchor nodes, wherein each subset has at least three anchor nodes. A distance from the target node to each of anchor nodes in each subset is measured, to estimate possible locations of the target node. A geometric constraint is applied to each estimated location to determine valid locations, which are then filtered to determine filtered locations. The filtered locations are averaged to determine an initial estimate of the location.

摘要： In a wireless network including a server and clients, network resources, such as time slots and channel frequencies, are managed by having the server define the resources for future use by the clients, while the clients actually allocate the resources for their exclusive use according to performance criteria determined by the clients. The network can be ad-hoc and in industrial environments with low-latency requirements.

摘要： Multiple routes from a data source node to multiple data destination nodes in a large scale multi-hop mesh network are discovered. Nodes discover multiple routes to two destinations in an initial discovery phase that includes only two network-wide flooding of packets. The method can also work with one destination. The method can be extended to include more destinations with a proportional increase in the communication overhead. After the completion of the discovery phase, nodes can communicate or forward their own or received data by using any of the available routes.
