Abstract:

The emulation is different from the simulation because the former uses real hardware to build an environment similar to the physical testbed. We have used RF hardware to create a wireless networking emulation platform that is easy to use and modular enough to allow users to quickly adapt the emulator to their own use. Specifically we have tested the communication performance of a routing protocol (Ad-Hoc On-Demand Distance Vector (AODV)) and a transport protocol (Pump Slowly Fetch Quickly (PSFQ)). Present results show that the ability to use a realistic wireless device provides additional constraints that need to be taken into consideration when designing a communication protocol.
