N2 - The performance of a conservative time management algorithm in a distributed simulation system degrades significantly if a large number of null messages are exchanged across the logical processes in order to avoid deadlock. This situation gets more severe when the exchange of null messages is increased due to the poor selection of key parameters such as lookahead values. This paper presents a generic mathematical model that uses null messages to avoid deadlock. Since the proposed mathematical model is generic, the performance of any conservative synchronization algorithm can be approximated. In addition, we develop a performance model that demonstrates that how a conservative distributed simulation system performs with the null message algorithm (NMA). The simulation results show that the performance of a distributed system degrades if the NMA generates an excessive number of null messages due to the improper selection of parameters.
