摘要： 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.
