Wireless Network Emulation System (WiNE)

摘要

Costly decisions about which wireless networking technologies to develop are currently being based largely on results from high-level simulation tools. The FCS-C program, for instance, used high-level simulation tools to select the network and radio software for final development and demonstration. To mitigate risk, there needs to be lab-based tools that provide more accurate assessment than simulation but at far less cost than field testing. Our approach to this problem is to develop a tool that emulates a field-test environment in the lab, so technologies under consideration can migrate from coarse simulation models to actual code and tested 'live,' in real-time, over a high-fidelity virtual wireless channel environment. Our current solution is the Wireless Network Emulator (WiNE). This report summarizes the development and testing that was conducted under this program. Notable achievements include the development of the first integrated prototype of the embedded distributed simulation engine, accompanied by a wonderful graphical user interface; and the development of detailed network, traffic, mobility, and environment models patterned after the FCS-C baseline field tests conducted at the Naval base in Lakehurst, NJ. Future work under consideration includes improvements in platform stability, support for HLA, new simulation models (specifically underwater and hybrid sensor networks), expanding the library of propagation, radio, and MAC models, and the development of a diverse set of virtual worlds.
