A unified model of evaluating the performance of route discovery in ad hoc networking

The frequency of route discovery is one of the main performance metrics in the mobile ad hoc networks with source-routing. Conventionally, this metric was derived from the exponential distribution. Although it might be appropriate to the scenarios directed mainly by the light-tailed traffic, the exponential model is inadequate to characterize the paradigms dominated by heavy-tailed traffic. In this paper, we propose a unified model to take both traffic types into account. Our model is based on the compound Weibull distribution, of which the exponential distribution and the Rayleigh distribution are special cases.
