Traditional approaches for testing MANET protocols and applications prior to field experimentation often involve simulation tools or small-sized physical testbeds. However, simulation tools typically do not run in real-time and rely on simplified models rather than a real system, while physical testbeds are prohibitively expensive to build and operate. A more practical method is to use emulation tools...
In this paper, we study the network queuing effects on the VoIP delay and jitter. Two service polices, FIFO and Differentiated Service (DiffServ), are studied with repect to the queuing delays of VoIP packets. First, we present our assumptions for delay characterization. Then, we provide a model for the traffic flow. We create a ??Markovian+Deterministic (M+D)?? model in order to represent the traffic...
