In trust-based models for MANETs, it is often assumed that the trust value between two nodes decays proportional to the time these nodes are out of transmission range of each other. The authors present in this paper an analysis of the trust decay rate for some general networking and trust computation models. Their analysis allows for the consideration of the subjective trust values assigned by present and past neighbours within a given history timeframe. The mobility models being studied in this paper include Random Way Point (RWP) and Random Walk (RW).
