1. A communications system, comprising:
- a plurality of mobile nodes forming a mesh network;
a plurality of wireless communication links connecting the mobile nodes together;
each mobile node comprising a communications device and operative for transmitting data packets wirelessly to other mobile nodes via the wireless communications link from a source mobile node through intermediate neighboring mobile nodes to a destination mobile node using a link state routing protocol and multiple waveforms, wherein each node is operative for predicting 1-hop neighboring connectivity using heuristics based on reception characteristics for a received packet on a base waveform that is chosen from the multiple waveforms wherein at least one of the multiple waveforms has a different range, transmission distance or reach that is greater than the other multiple waveforms resulting in different connectivity.

Abstract
A communication system includes a plurality of mobile nodes forming a mesh network. A plurality of wireless communication links connect the mobile nodes together. Each mobile node is formed as a communications device and operative for transmitting data packets wirelessly to other mobile nodes via the wireless communications link from a source mobile node through intermediate neighboring mobile nodes to a destination mobile node using a link state routing protocol and multiple waveforms.
