The two main research pillars conducted at UW under this effort include:<\/p>\n<ol>\n<li>For cross-layer network simulation in ns-3, PHY abstractions for increasingly complex transmission scenarios are a necessity (and a significant barrier\/opportunity toward the creation of better simulation frameworks). The project confronted this head-on via exploration of continuing advances on PHY layer abstractions for use in ns-3 at simulation run-time.<\/li>\n<li>Simulation tools and hardware testbeds have developed independently, resulting in different workflows, terminology, and APIs for users who may want to use them as complementary within a hybrid co-simulation\/emulation with HW in loop-cum-experimentation approach. POWDER, U. Utah (<a href=\"https:\/\/powderwireless.net\/\">https:\/\/powderwireless.net\/<\/a>) can support fine-grained scripting and repeatable testbed experiments. This component focused on better alignment of ns-3 with POWDER as the target infrastructure for running ns-3 programs.<\/li>\n<\/ol>\n<ul>\n<li>Personnel: Sumit Roy (Principal Investigator), Tom Henderson, Sian Jin, Hao Yin<\/li>\n<li>Collaboration: Centre Technologic Telecomunicacions Catalunya (CTTC Barcelona), IMDEA Networks<\/li>\n<li>Publications:\n<ul>\n<li>T.
