Abstract
A multi-tone synchronous collision resolution system permits communication nodes within a MANET to contend simultaneously for a plurality of available channels. The communication nodes contend for access using a synchronous signaling mechanism that utilizes multiple tones in a synchronous manner to resolve contentions. Contentions are arbitrated locally, and a surviving subset of communication nodes is selected. The communication nodes of the surviving subset then transmit data packets simultaneously across the available communication channels.
