Simulators for WSN
The Simulator is universally used to develop and test protocols of WSN, especially in the beginning stage of these designs. free ppt download
1. Introduction to simulator
2. Simulators for WSN
10. ConclusionINTRODUCTION TO
1. The Simulator is universally used to develop and test protocols of
WSNs, especially in the beginning stage of these designs.
2. The cost of simulating thousands of nodes networks is very low, and
the simulation can be finished within very short execution time.
3. Both general and specialized simulators are available for uses to
simulate WSNs.SIMULATORS FOR WSN
6. ATEMU, and
1. NS2 is the abbreviation of Network simulator version two, which
first been developed by 1989 using as the REAL network
2. Now, NS2 is supported by Defense Advanced Research Projects
Agency and National Science Foundation.
3. NS2 is a discrete event network simulator built in ObjectOriented
extension of Tool Command Language and C++.
4. People can run NS2 simulator on Linux Operating Systems or on
Cygwin which is a Unixlike environment and commandline
interface running on WindowsMERITS
1. NS2 can support a considerable range of protocols in
2. The open source model saves the cost of simulation,
and online documents allow the users easily to modify
and improve the codes.LIMITATIONS
1. people who want to use this simulator need to
familiar with writing scripting language and modeling
2. sometimes using NS2 is more complex and time
consuming than other simulators to model a desired
3. NS2 provides a poor graphical support, no
4. due to the continuing changing the code base, the
1. TOSSIMis an emulator specifically designed for WSN running on
TinyOS, which is an open source operating system targeting embedded
2. In 2003, TOSSIM was first developed by UCBerkeley’s TinyOS
3. TOSSIM is a bitlevel discrete event network emulator built in
PythonPython, a highlevel programming language emphasizing code
readability, and C++.
4. People can run TOSSIM on Linux Operating Systems or on Cygwin
1. The open source model free online document
save the emulation cost.
2. TOSSIM has a GUI, TinyViz, which is very
convenience for the user to interact with electronic
3. TOSSIM is a very simple but powerful emulator
4. TOSSIM can support thousands of nodes
1. TOSSIM can not correctly simulate issues of the energy
consumption in WSN;
2. Every node has to run on NesC code, a programming
language that is eventdriven, and implemented on TinyOS,
3. Moteslike nodes are the only thing that TOSSIM can
1. EmStar is an emulator specifically designed for WSN
built in C.
2. It was first developed by University of California, Los
3. EmStar is a tracedriven emulator running in realtime.
4. People can run this emulator on Linux operating systemMERITS
1. EmStar has a robustness feature that it can mitigate faults
among the sensors.
2. There is a flexible environment in EmStar that users can
freely change between deployment and simulation among
3. EmStar has a GUI, which is very helpful for users to control
It can not support large number of sensors
The limited scalability will decrease the reality of
EmStar is can only run in real time simulationOMNET++
1. OMNeT++ is a discrete event network simulator built in C++.
2. OMNeT++ provides both a noncommercial license, used at
academic institutions or nonprofit research organizations, and a
commercial license, used at "forprofit" environments.
3. Users can run OMNeT++ simulator on Linux Operating Systems,
Unixlike system and Windows.MERITS
1. OMNeT++ provides a powerful GUI.
2. This simulator can support MAC protocols as well as some localized protocols
3. OMNeT++ can simulate power consumption problems in WSNs
1. The number of available protocols is not larger enough
2. The compatible problem will rise since individual researching groups developed
the models separatelyJSIM
1. JSim is a discrete event network simulator built in Java.
2. This simulator provides GUI library, which facilities users to
model or compile the Mathematical Modeling Language, a“text
basedlanguage” written to JSim models.
3. This simulator is commonly used in physiology and biomedicine
1. models in JSim have good reusability and interchangeability
2. JSim contains large number of protocols
3. can simulate radio channels and power consumptions in WSNs
4. JSim can simulate larger number of sensor nodes, around 500.
1. The execution time is much longer
2. The inherently design of JSim makes users hardly add new protocolsATEMU1. ATEMU is an emulator of an AVR processor for WSN built in C
2. AVR is a single chip microcontroller commonly used in the
3. ATEMU provides GUI, Xat db; people can use this GUI to run
codes on sensor nodes, debug codes and monitor program
4. People can run ATEMU on Solaris and Linux operating system.MERITS
1. ATEMU can simulate multiple sensor nodes at the same time.
2. ATEMU has a large library of a wide rage of hard devices.
3. ATEMU can provide an accurate model
1. The simulation time is much longer than other simulation tools
2. ATEMU has fewer functions to simulate routing and clustering
1. Avrora is a simulator specifically designed for WSNs
built in Java.
2. Similar to ATEMU, Avrora can also simulate AVR
based microcontroller MICA2 sensor nodes.
3. This simulator was developed by University of
California, Los Angeles Compilers Group.MERITS
1. It is an instructionlevel simulator, which removes the gap between TOSSIM
2. It can support thousands of nodes simulation, and can save much more
3. It provides larger scalability and more accuracy
1. It does not have GUI
2. Avrora can not simulate network management algorithmsCONCLUSION
1. Simulation of WSN is an important research area because of the amount
of the sensor nodes participating in typical network.
2. The purpose of this survey is to give a general picture of mainstream
simulation tools using in WSNs, and help people to choose different
simulation tools according to different needs
3. This survey analyzes seven mainstream simulators: NS2, TOSSIM,
EmStar, OMNeT++, JSim, ATEMU, and Avrora, and compares their merits
and limitationsAny queries
