Assignment Description

Task 1
Wireless networks performance varies from wired networks, the latter uses a guided medium and
wireless networks use unguided medium for transmission. To design and simulate wireless networks
the network simulator - 2 (NS - 2), an open source discreet event simulator could be used. The NS-2
simulator is a widely used simulation tool, which could generate trace files for analysis and comes
with a network animator to visualize the network performance.

This assessment requires students to compare and evaluate the performance of wireless routing
protocol using the NS - 2. The assessment requires students to design a wireless network topology in
NS - 2 and evaluate the generated trace files for a wireless routing protocol. The students are required
to ca
y out a critical analysis of the results of the protocol by plotting graphs and discussing the
outcomes.

The students are required to:
 Design a wireless network consisting of 25 nodes; the dimensions for the given topology are
1000x800. The agent type should be User Datagram Protocol (UDP) and the traffic Constant
Bit Rate (CBR). The simulation should run for 300 seconds. Random deployment of nodes is
equired and the nodes are required to transmit packets over the network. The wireless node
configuration should include the NS - 2 energy model.
 Run the simulation on routing protocol Destination Sequenced Distance Vector Routing
(DSDV) and Ad hoc On DemandDistance Vector (AODV). Critically analyse the trace files in
terms of packets sent, received and dropped. These parameters should be plotted on graphs
and discussed in detail.
 Include screenshots of the NAM (Network Animator) displaying the nodes deployed during
the simulation and add screen shots of the simulation.
 Conduct comparative analysis on the results for packets sent, received anddropped for the
two protocols.
 Appendix I should include the tcl srcript used in each simulation.

Task 2
Smart home or home automation technology provides homeowners’ security, comfort, convenience
and energy efficiency by enabling them to control smart devices, via an app on their smartphone or
other networked device. This technology enables you doing things such as turn the lights on/off,
stream music to a speaker, lock/open the doors remotely, and much more.
This task aims to simulate a smart home using Internet of Things (IoT) technology in Cisco Packet
Tracer. Students will purely practice with the IoT component offered by the Cisco Packet Tracer to be
used in the home. Those IoT devices will be connected to the home WLAN that enables the users to
control the things through wireless technology. The users should also be able to control the things
when they are outside home (remote access). This means the WLAN should be connected to a global
network that enables the users to have control on devices when they are at work.
The students are required to complete the following steps:
 Explore the ethical implications in the design and implementation of Wireless Local Area
Networks (WLANs).

This design will be used to generate the script for the analysis of the network and in the last it will generate the output (Khandakar, 2012).
In the given image the network is been design with some specific number of nodes. The UDP number is been defined for the specific number of nodes and then it is been set to default for some specific set of duration. The links in between the nodes can be easily determined with the blue color. The connection is been setup in the given linkage with the speed of 1000 bytes.
The above image showing the scenario is been developed over the NSG as per the given simulation part of the scenario.
The given image clearly showing the communication channel in between the two different nodes that are been done by transfer the packets in between the two different nodes.
This is the connection file of the different nodes that are been design above. The c
size for the given network simulation is been set to the 210 c
. When the communication is been done in between the two different nodes then the destination, source address been stored with the proper sequence number and the proper packet ID.
3. NS - 2 Trace file analysis
For the analysis of the tracer file for the designed network design two different router protocol are been used in the simulation i.e. DSDV and AODV. The given is the screen shot for the tracer file that is been used for the design simulation.
The given screen shot is the screen shot for the analysis of the DSDV part over the simulation. The given number showing the number of nodes that are been communicated with each other. The above case specify the communication in between the neighbor (Gupta
Saket, 2011).
The above screen shot showing the AODV protocol for the tracer file that is been done in between the different nodes. The node transfers the data at 1000 bytes to the c
. The connection is been setup in the nodes that is been used to transfer the packets with the help of AODV packets. The packet of the communication is been transfe
ed to the nearest nodes.
4. NS - 2 Simulation Results Analysis
In the given section of the report the analysis of the routing protocol is been analyzed. The network is been designed for the NS2 for the network simulation.

ed from one location to the another thorough the given time interval.
The above graph showing the DSDV platform, that is performing the analysis the nodes over the specific time interval. The graph is been showing the output of the packets that are been transfe
ed from one location to the another thorough the given time interval.
5. Explore Ethical Implication
This section includes the morality of the function that is used to make the decision of the communication in between the two different nodes. During the designing the node of the network there are many different ethical dilemmas are been analyzed that are seen while designing the network.
While designing the network the privacy and the decision making the first network dilemmas that are been faced. While on the other hand the third issue of ethical implication is been found is the events, accuracy and retention of the network.
For the removal of the issue the best suited design is been designed for the work that make the design capable for the ethical implication.
