Introduction of WSN

Wireless Sensor networks are a particulartype of adhoc network.

WSN formed by a large no of nodes.

Nodes:physical device monitoring a set of physicalvariables

communicates via a redio channel.


3/22

Introduction of WSN(Cont)

Nodes:Internally protocol stack controlscommunications.

WSN can be considered as a particular typeof MOBILE AD-HOC NETWORK(MANET).


4/22

Design challenges

Energy conservation

Unstructured and/or time-varying networktopology

Low quality communications


5/22

Design challenges(Cont)

Resource-constrained computation:

Protocols for ad-hoc networks must strive toprovide the desired proformance level

in spite of the few available resources.

Scalability:protocols must efficiently operatein presence of a large no of nodes.

What is simulation environment?

Simulation environment that can be used tosimulate wsns,

covering simulation environment that wereextended to support wsns.


9/22

simulation environment(Cont)

Adaptive Development: Covers simulationenvironments that already existed.

New Development: Covers new simulatorswhich were created solely for simulating wsn.

Different types of Simulation

Environments

GloMoSim /QualNet: (version 2.0 Dec 2000/0.5 Nov2009)

Scalable simulation environment,

Written by parsec a C based simulation language.

windows xp & unix windows supports.

It can support MOBILITY.

Simulation Environments

OPNET Modeler Wireless Suite:

(Version 16.0,released Dec 2009).

It is developed by OpNet Technologies.

provides an Object-Oriented modeling

approaches .

It supprots MOBILITY

Simulation Environments(Cont)

OMNeT++: (Version 4.0 March 2009)

Object Oriented Discrete network simulator framework.

Basic modules C++;larger structure NED.

Active project with huge user base.

Supports MOBILITY.


15/22


J-Sim : (version 1.3 + patch4 Jul 2006)

Component based compositional simulationenvironment.

It supports autonomous componentarchitecture.

Written by object oriented technology likejava.

Includes sensor packages.


16/22


Avrora : (Version Beta 1.7.106 Aug 2008)

Simulation and simulation tools.

AVR microcontroller binaries.

Implemented bt Java.

Supports diffreent sensor platform suchas Mica2 and Mica Z


17/22


SENSE : (3.1 Nov 2008)

Sensor Network Simulator and Emulator.

promotes reusability & extensibility.

programming language is c++.SENSE based on COST.

It includes battery and power models.

supports protocols like MAC layers(IEEE-802.11).


18/22


TOSSIM (Part of tiny OS) : (Version 2.1.1 Apr2010)

A discrete event simulator.

It takes the advantages of Component BasedArehitecture of Tiny OS.

programming Language is nesCa c based

language.It has external communication system.
