3.2 Simulator
Various methods available to measure the performance of data communication protocols involving live network tests, hardware emulation, test-beds and mathematical models. Software simulation, since, is usually a time effective and cost efficient method. Researchers around the globe are utilizing software simulation tools because it offers a controlled atmosphere within which any network model performance can be measured easily and efficiently.
Nowadays, the popularity of the available network simulators and specifically that of Ad Hoc networks varies from one simulator to another. Besides, each simulator depends on its own methodology and models to model a real network.

NS-2 offers a poor graphical support, no Graphical User Interface (GUI), the subscribers have to directly face to text commands of the electronic devices.
Because of the continuing modifying the code base, the result may not be consistent and consist bugs.
NS-2 cannot simulate issues of the power consumption, bandwidth or energy saving in WSN. NS-2 has a scalability issue no. of nodes cannot be greater than 100.
3.2.2 GloMo Sim
GloMoSim is a scalable simulation atmosphere for wired and wireless network systems, formulated by PCL (Parallel Calculation Laboratory) of UCLA ( the University of California in Los Angeles). It utilizes Parallel Simulation atmosphere for Complex System (PARSEC) that is a C-based simulation language for parallel and sequential execution of Discrete event simulation model. Glomosim Supports protocol for a purely wireless network.
Advantages:-
Network model scalability can be increased up to thousands of nodes.
GlomoSim is helpful for a network model where nodes are interchanging a large amount of information.
Limitations:-
The GloMoSim updates are not regular. The last update was in …show more content…
slow Java-based User Interface. very costly.
3.2.4 NETSIM
NetSim offers complete model creation and changes abilities along with graphical animation and data output. Netsim utilizes the event graph mechanism and object-oriented programming for simulation. Netsim is a world wide web-based simulation package written completely in Java. NetSim permits expandability for complicated modeling and integration with other Java-based programs i.e. graphing and analysis packages.
Any simulation issue modeled in NETSIM can be seen as an HTML page like JAVA applet. It offers conventional procedural based simulation package.
Advantages:-
it is existed in all platforms without recompiling. It can be accessed remotely as modeling is JAVA applet based.
It offers security by password technique for individual access, and protect against unauthenticated change and delicacy.
High maintenance as frequent changes is instantly distributed. All changes and implementation are built on-sever.
Encourage interaction and communication through java and needs Browser capable of running JAVA programs.
