in an ORC (object-oriented real-time computing) environment, it is important to reduce message retransmissions during message passing because these retransmissions cause significant time delay. And, this makes it difficult to achieve the necessary timeliness. A cause of retransmission is message loss due to buffer overflow at the reception side. Here a p+i+d (p for proportional, i for integral andd for derivative) adaptive buffer controlalgorithmis proposed to prevent such possible overflow. The icontroldepends on the Convergence algorithm (CA), which is a stable and efficient iEpM (internet End-to-Endperformance Measurement) toot that predicts the mean message roundtrip time (RTT) of a communication channel quickly and accurately,. The p+i+dalgorithm was tested under different conditions in a mobile ORC (MORC) environment, where mobile agents collaborate freely over the internet. The different test results confirm that the proposedp+i+d approach is indeed effective for preventing buffer overflow.
