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.
Claims26
A channel assignment scheme for a node of a mesh network, comprising:
- the node determining a number of hops between the node and a server of the mesh network;
- assigning a first channel to an uplink for the node;
- assigning a second channel for a downlink for the node;
- maintaining the first channel and the second channel distinct from an uplink channel of an upstream node;
- wherein the assignment of first channel and the second channel for the node is based on the number of hops between the node and the server.
A channel assignment scheme for a node of a mesh network, comprising:

- assigning a first channel to an uplink for the node;
- assigning a second channel to a downlink for the node;
- maintaining the first channel and the second channel distinct from an uplink channel of an upstream node;
- and
- assigning the first channel and the second channel for the node based on a number of hops from the node to the server and a number of available channels.
A node comprising:
- a transceiver having two interfaces, wherein each interface has a channel;
- and a channel manager, the channel manager to assign a first channel for a first interface to an uplink for a node and a second channel for a second interface to a downlink for the node, wherein the assignment of first channel and the second channel for the node is based on a number of hops from the node to a server.
