Abstract:
1. A method for identifying neighbor nodes in an ad-hoc wireless network including a plurality of nodes, comprising: generating a beacon signal at a first node of said network for alerting other nodes in said network of the presence of said first node, said beacon signal comprising beacon data and having a data rate, said beacon data including information specifying at least one of a data initialization parameter and a network characteristic that is useful for establishing a communication link between said first node and said other nodes of said network; digitally generating a first chaotic spreading sequence at said first node; modulating said beacon signal with said first chaotic spreading sequence to produce a spread spectrum beacon signal; and transmitting said spread spectrum beacon signal at a first power level without risk of detection, wherein said first power level exceeds a second power level at which a beacon signal could be transmitted without risk of detection using a non-chaotic spreading code.
