1. A method of improving signal quality in an ad hoc on-demand distance vector (AODV) mesh network, comprising:
- detecting at a node the signal quality of a received AODV protocol message;
comparing the signal quality of the received AODV protocol message to a threshold; and
on detecting that the signal quality of the received AODV message is not above the threshold, dropping the received AODV message.

Abstract
A method of improving signal quality in an ad hoc on-demand distance vector (AODV) mesh network, comprising detecting at a node the signal quality of a received AODV protocol message, comparing the signal quality of the received AODV protocol message to a threshold; and on detecting that the signal quality of the received AODV message is not above the threshold, dropping the received AODV message. Further, a method of improving AODV mesh operation by detecting at a node the signal quality of the RREQ messages received at that node; and dropping any RREQ messages for which the signal quality is not above a threshold.

11. A method of establishing a route with acceptable signal quality in a wireless mesh network, comprising:
-
transmitting at a first node a route request message, wherein the route request message requests a route connecting to a second node; carrying out at least at a node at which the request message is detected the steps of; determining from which node the route request message was received at the node; determining whether the signal quality of the route request is above a threshold; and retransmitting the route request message if the signal quality was determined in the previous step to be above the threshold, and dropping the route request message if the signal quality was determined in the previous step not to be above the threshold; receiving at the second node the route request message; transmitting a reply message from the second node to the first node; on detecting at the second node the route request message with, sending a reply message indicating that a route has been found to the node from which the route request message was received at the second node; at the node from which the route request message was received at the second node, if that node is not the first node, retransmitting the reply message indicating that a route has been found to the node from which the route request message was received at that node; and repeating the previous step until the reply message indicating that a route has been found is received at the first node. - View Dependent Claims (12, 13, 17)

14. A method of establishing routing tables for improving signal quality in a wireless mesh network, comprising:
-
transmitting a message from a first node; detecting and measuring the signal quality of the message at a second node; comparing the signal quality of the message to a threshold; and updating a routing table at the second node so that the routing table includes the first node as a neighbor node only if the signal quality of the message is above the threshold. - View Dependent Claims (15, 16)

19. A method of improving signal quality in a wireless mesh network, comprising:
-
detecting at a first node a signal quality of a transmission from a second node; comparing the signal quality of the transmission to a threshold; and allowing the link between the first node and the second node to be used in a route only if the signal quality is above the threshold, in which the threshold is varied at the first node depending on at least one of A) the number of other nodes the signal quality from which has been detected at the first node to be above the threshold, and B) the load transmitted by the first node. - View Dependent Claims (20, 21)
