We compare the performance of two real-time multimedia communication systems for quality versus end-to-end delay. We develop an analytical framework for comparison when the systems use a deterministic time-varying channel. Moreover, we assess their performance for the Gilbert-Elliott channel model which alternates between a good and a bad state with time durations that are exponentially distributed...

Unlike malware that propagates using the network, where the provider can employ centralized defenses, proximity malware can propagate in an entirely distributed fashion. In this...
