What about use the same algorithm used in ethernet when a collision is detected? When a collision occurs: 1) Stop sending. 2) Wait for some random amount of time between 0-T seconds 3) Try again. 4) If collision occurs again, increase T using an algorithm, go to Step 2. algorithm: T = rand ( 2n -1 ) * 51.2 ms where n- number of collisions Regards Gaetano Mendola ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
