Tato práce zkoumá vhodnost a požadavky návrhu simulací pro simulátor NS-3 pro případ bezdrátových sítí používaných v měřící infrastruktuře společnosti Kamstrup. V práci jepopsán simulátor NS-3 a je vytvořena základní implementace dvou protokolů. WirelessM-Bus jako příklad jednosměrného protokolu pro zařízení napájené z baterií. Simulace Wireless M-Bus je porovnána s daty naměřenými v reálném systému. NS-3 poskytuje flexibilní prostředí pro vývoj simulací různých síťových protokolů, včetně těch určených pro sítě inteligentních měřidel.
A.OTHER SIMULATORS
There are several simulation tools available, with different features, licenses and
target uses.3 NS-3
The first release NS-3 was made 2008.4 WSNet
WSNet project specialized for large scale wireless networks [12].1 Omnet++
Omnet++ modular network simulator with wide range modules with differ-
ent features, including wireless sensor networks. completely new simulator, trying
to overcome the problems NS-2, especially the complicated use two languages,
some bad design decisions [11] and the emergence several incompatible forked
versions it.
A.
While still being maintained, not under very active development, because
of its successor, NS-3.2 NS-2
NS-2 used very popular network simulator, with several projects expanding
it for more specific tasks.
The network structure defined using special language called NED, while the
library itself based C++.
A.
A. also includes graphical interface
integrated with Eclipse.
Even though NS-3 does not support many protocols NS-2 does, there is
already work progress implement 6LoWPAN and RPL [10], which are suitable
for mesh networks. The networks
are defined XML files, while the modules are defined C.
It based C++ and OTcl.

NS-3 written C++ and has Python bindings allow writing simple
scripts Python well. Several network simulators were considered: Omnet++, NS-2 and NS-
