Abstract

A self synchronizing network protocol which allows networks to become self synchronizing. Two pairs of nodes communicate in an ad hoc packet radio network. Packets are communicated over a plurality of frames of time. A known bit field is appended to each packet. A clock at the first pair of nodes (10 and 12) is unavoidably slower than the clock at the second pair of nodes (14 and 16). As a result, packets transmitted from the second pair of nodes (14 and 16) will eventually overlap packets transmitted from the first pair of nodes (10 and 12). Errors in the appended field (17) can be used to detect such an overlap in advance to prevent damage to the payload. The protocol provides for additional channel efficiency, more responsiveness and the ability to grow without a central controller. Further, the ability to accommodate new traffic is increased.
