Performance of selective packet dropping policies in heterogeneous networks

The performance analyses of selective packet dropping policies have usually been performed using homogeneous traffic sources and under one node scenarios. In this paper we focus our attention not only on heterogeneous sources but also heterogeneous environments. We present simulation results of application level performance for heterogeneous traffic sources under three different packet dropping schemes: partial packet discard (PPD), early packet discard (EPD), and preemptive partial packet discard (pPPD). In addition, we also present simulation results for homogeneous sources over multi-hop networks with heterogeneous packet dropping policies
