Network link controller
First Claim
1. A method of designating a master node in a network containing a plurality of nodes, each node having a frequency range and a transmission frequency, comprising the steps of:
- designating one of the nodes as an initial master node; and
, for each other node of the plurality of nodestransmitting a packet header from the initial master node to the other node in the network at a first frequency, the packet header including a status indicator indicating master node status;
responsive to receiving the packet header including the status indicator at the other node, scanning the frequency range of the other node to lock onto the first frequency and setting the frequency range of the other node to match the first frequency; and
responsive to not receiving the packet header including the status indicator at the other node, transmitting a packet header from the other node with a status indicator indicating master status.

Abstract
A link controller for use in a node of a network includes a digital controller (102) that employs a knowledge-based control program (103). The device and method provide flexible master node designation, automatic installation, configuration and reconfiguration, and recognition and correction of network communication problems resulting from interference and other adverse conditions. The knowledge-based control program (103) employs an inference engine and a set of rules to dynamically optimize network configuration. Multipath is managed by locking on to reflected signals when a direct signal is unavailable. Operation is transparent to network users.

2. A method of designating a master node in a network containing a plurality of nodes, each node having a frequency range and a transmission frequency, comprising the steps of:
- for each node
scanning the frequency range of the node to determine whether a master packet has been transmitted by another node; responsive to the determination by a node that a master packet has been transmitted by another node, matching the frequency of another node; responsive to the determination by a node that no master packet has been transmitted by another node; selecting a frequency; and transmitting a master packet at the selected frequency.
