In this emulation, original diagram configuration in DCS and field hardware structures are kept unchanged.
Emulation triggers can emulate arbitrary cross-layer feedback and can be synchronized with other emulation effects.
In order to reduce the emulator latency, several expedients have been played out, such as disabling configuration Telnet commands when the emulation is running, or selecting among different level of the logger verbosity in order to reduce the time spent to save data to the SD card.
Nevertheless, the concept of software-hardware co-simulation suggests a new hybrid approach: the transceivers can be implemented in software, giving researchers absolute configuration control and flexibility, whereas the channel emulation can be run on hardware, thus accelerating channel emulation and the overall simulation process.
Thus, there remains residual self-interference at the relay, that is modeled as a fading channel which, by its turn, allows the emulation of various (non)line-of-sight configurations arising from antenna isolation and interference cancelation techniques [9, 10, 15 17].
The emulation behavior is controlled by a set of configuration items, which can be adjusted as necessary to emulate a specific scenario.
However, such emulation systems are difficult and expensive to deploy, and their management and configuration are complex.
The concept of emulation triggers as a mean for supporting emulation of opportunistic networking configurations that are dependent on lower layer dynamics was introduced in [19].
Experimental results are provided for a hardened 8051-like microproceshowingowing that the presented emulation environment reaches the theoretical optimal performance for a wide range of fault configurations using our proposed optimizations.
Nor was emulation of Western art.
