Abstract
A method and system for adjusting a message preamble on a shared bus, wherein the message preamble includes N synchronization characters, and each of the synchronization characters is separated in time by a random delay interval. First, an activity status is determined for the shared bus in terms of the number of stations that are currently active on the bus. The number of synchronization characters is then adjusted according to the bus activity status. The activity status is also utilized as a dynamic adjustment parameter for the random delay interval that includes a fixed delay term, D, added to a randomly determined delay increment, d. In this manner the message preamble specification is optimized according to real-time network demands, such that latency and data collisions are minimized.
