Abstract:

This report focuses on the design, development, and testing of a prototype Network Frequency Selection Service NFSS that would automate the selection of a single, best frequency for operation of a single-channel network. After selecting the operating frequency, the NFSS proceeds to set the client networks transmitter and receiver to the chosen frequency. The NFSS is intended to be used as a scheduled service. During the periods when the NFSS is active, it normally tests a subset of the candidate frequencies, along with the previously chosen best frequency, and chooses the new best frequency from among this subset. Eventually, over several such active periods, all candidate frequencies are tested. The client network operates in its normal manner between activations of the NFSS. In the prototype NFSS, the best frequency is the one that minimizes the frequency selection metric, which contains, in order of importance 1 the number of relay nodes disconnected from the main body of the network, 2 the number of relay nodes needed to form a backbone network, 3 the number of links that the given topology falls short of being a fully connected network, and 4 the index of the frequency in the sequential collection of candidate frequencies.
