Abstract
A method and apparatus for routing messages in a wireless network. Transmissions from all devices are synchronized. Each device is equipped with a routing unit that checks incoming messages for integrity, discards “corrupt” messages, compares non-corrupt messages to the last transmitted message, and applies a set of rules to determine when and what the device should next receive or transmit. The synchronized transmissions and integrity checking process detect true collisions, which occur when multiple transmitters have attempted to send different messages to the same receiver. The comparing process ensures that messages are transmitted only if not previously transmitted, thereby avoiding loop problems.
