Space Internet - Transmission of Large Files

Presentation slides, demo slides, and final report (PDF files).

Abstract:
The internet has become the backbone of most of our everyday life. This implementation first conceived in the 1960.s, has survived and evolved with the times and continue to evolve to serve our demands. The demand for bandwidth, speed, low delay, and low error rate has been a challenge for researchers and network analysts. As humans venture into space, it would be beneficial to maintain access to the internet throughout our solar system.

There have been developments and advances by NASA and other researchers [1] to standardize methods for such system. A system currently being developed and honed to tolerate massive amounts of delays, error rates and disconnections, is called Disruption Tolerant Network (DTN) [2]. This project will simulate the implementation of the DTN and explore the downfalls of this network. There are active researches in the development of congestion management, multicasting capability, and routing protocols [3], our group will continue to gather recourses to fine tune the scope of our project. At the very least we will compare the implementation of DTN and the current IP protocol model and test various of disruption methods when transferring large files, such as: disconnections, huge delays, and high error rates. DTN uses naming, layering, encapsulation, and persistent storage to interconnect heterogeneous portions of a large network, irrespective of formal layer [4]. We will observe speed and bandwidth and overhead usage when handling such these scenarios.

Evaluation and Comparison of Spanning Tree Protocol and Rapid Spanning Tree Protocol on Cisco switches via OPNET

Presentation slides, demo slides, and final report (PDF files).

Abstract:
Our project intends to evaluate and compare the performances of STP and RSTP on Cisco switches supported by OPNET. We were planning to do the comparison of STP with more other types such as Multiple Spanning Tree Protocol. However, after searching in OPNET V16.0, we found that in OPNET, Cisco switches only support STP and RSTP.

Our project will first introduce some background information regarding VLAN, STP, RSTP, Layer Two Switches, Layer Three Switches, Distribution Layer, Access Layer, and so on. Besides the background information, our project will discuss some companies that produce switches, especially the one's switches we will be using: Cisco.

Our project then will include our work on OPNET. We are planning to build and configure the topologies, then analyze and explain some snapshots taken from OPNET. We will create STP tree with three layers which totally have approximately ten Cisco switches, and observe the performance of connection coming back up after disconnecting the loop. After finishing the STP evaluation, we will run the same procedure for RSTP, and finally compare their results for a conclusion.

The Analysis and Simulation of VoIP

Presentation slides, demo slides, and final report (PDF files).

Abstract:
Recently, a communication method called .Voice over Internet Protocol. (VoIP) has grown to be very popular, and it is gradually replacing Public Switched Telephone Network (PSTN) as the best choice for voice communication. VoIP is a protocol that allows people to make calls over the internet. It has many advantages over the traditional telephone line such as the cheap cost and the ability to perform group conversations. However, it also has many drawbacks. In this project, we will analyze and evaluate the potential deficiencies of VoIP such as jitter, latency, and bandwidth issues. We will be performing the analysis by using ns-2. After we compare the advantages with the disadvantage, we will also give our opinion on whether VoIP is the future of voice communication.

BACnet Network

Presentation slides, demo slides, and final report (PDF files).

Abstract:
BACnet, as known as data communication protocol for building automation and control networks, currently does not have a standard way to control the network traffic. In order to optimize the protocol, a new system mechanism to control the data flow in each node is necessary. The goal of this research is to improve the efficiency and the accuracy of the network. The method used to approach to the solution is by calculating the data drop rate from average queue length and data priority. Then with the obtained data drop rate, we can control the data flow to each BACnet station in order to reduce the service delay time, improve the reliability of the network, and minimize the probability of error.

Analysis of RIP, EIGRP, and OSPF Routing Protocol using Opnet

Presentation slides, demo slides, and final report (PDF files).

Abstract:
Long Term Evolution (LTE) is an IP based technology that has quickly become a leading global standard for 4G cellular networks. In order to keep up with traffic growth demands, the 3GPP (Third Generation Partnership Project) developed LTE technology with the goal of increasing capabilities and system performance, while reducing network complexity and minimizing costs. This technology improves quality of service and minimizes latency using a packet-switched approach. LTE.s increased data rate makes high-resolution video streaming possible. The focus of this project will be to simulate LTE video traffic patterns using Opnet. Furthermore, we will analyze the simulation results, evaluate Quality of Service (QoS) and compare performance with current industry standards.

Peer to Peer Networks

Presentation slides and final report (PDF files).

Abstract:
Peer-to-Peer networks are networks that enable computers traditionally used for client-based applications to be used as client or server based applications. This type of network enables users to access/share files and information from a multitude of other users rather than relying on a dedicated server. This type of network makes better use of the capabilities of modern personal computers which have become widespread around the world. In this project we will simulate and analyze these types of networks, measure their performance and contrast it with other types of networks. Most likely, we will be trying both software NS-2 and OPNET in order to execute the project from multiple angles.

Wireless Network Simulation

Presentation slides, demo slides, and final report (PDF files).

Abstract:
Our primary motivation to simulate wireless networks is due to the fact that a great share of our current innovation and everyday life directly involve this technology. The recent 30 years has seen an explosion of wireless networks into everyday use and the result has seen our lives become increasingly dependent on various wireless networks for communications, entertainment, business, and research. The strength of a wireless signal may vary widely depending on distances between devices, the surrounding environment, and device structure. We would like to test the capabilities of modern wireless devices with regards to signal strength by running wireless networks through different environments and scenarios. The program we have chosen to simulate the scenarios is NS-2. NS-2 is a powerful tool that allows users to not only simulate various networking scenarios (wired and wireless) but also to visualize each simulation. It is also flexible due to the ability of users to add to the current ability of NS-2 by coding additional features themselves.

Comparative Performance Analysis of LTE Versus WiMAX Using OPNET Simulation Modeler

Presentation slides, demo slides, and final report (PDF files).

Abstract:
The wide spread use of wireless devices and in particular smartphones has resulted in the rapid rise for greater capacity and speed of existing network technologies. To this end, LTE (Long Term Evolution) and WiMAX (Worldwide Interoperability for Microwave Access) became the two leading technologies considered for adoption to address this need. In the last two years, LTE has gained far greater support and adoption in the industry thus leaving WiMAX future prospects limited. In our project we intend to investigate the performance characteristics of both LTE and WiMAX. We will utilize OPNET 16 to simulate various cases (mainly single/multiple mobile stations and single/multiple base stations) and compare and contrast the latency, throughput and other performance characteristics of each of the respective wireless broadband technologies with the hope that the results we obtain clearly illustrate one technologiesÕ superiority over the other.

Comparison between LTE and Rival Wireless Technologies

Presentation slides, demo slides, and final report (PDF files).

Abstract:
Long-term-evolution (LTE) is a fourth generation (4G) wireless network for cellular devices. LTE is the natural successor to HSPA+ 3G networks, providing higher capacity, lower latency and a simplified architecture. We would like to explore the claims made by LTE as a superior technology through simulation of LTE against multiple other wireless technologies like High-speed-packet-access (HSPA), WiMAX and/or Wi-Fi. We plan to measure and compare capacity, latency and spectrum efficiency. Based on the results, we will be able to make conclusions about the validity and extent of LTEùs superiority over its rival wireless communication technologies.

Abstract:
Wi-Fi has become the most popular/common wireless technology that allows number of electronics devices to exchange data over a computer network. This includes high speed internet connection resulting in a very fast and convenient way to stay connected. Wi-Fi is basically known as üWireless Local Area Network (WLAN)ý, which uses a certain internet protocol known as üInstitute of Electrical and Electronics Engineers (IEEE 802.11 standards)ý. These days Wi-Fi is used from personal computers to smartphone to even printers as well as numerous wireless devices and all these can be connected through a single wireless (Wi-Fi) Network. Our task in the project is use Ns-2 simulatorùs wireless capability to simulate and get a concise understanding of how efficiently packets get transferred through different devices under the same network and also check to see whether any further improvements can be made.

An Analysis of Peer-to-Peer Traffic over an Ad-Hoc Network

Presentation slides, demo slides, and final report (PDF files).

Abstract:
Peer to Peer file transfers will only increase in popularity as more information becomes distributed and more devices become network enabled. Our project seeks to model P2P traffic using Bluetooth devices in a noisy environment in comparison with one that has no traffic in an attempt to find points for improvement. In order to accomplish our project goals, we are planning to use the ns2/ns3 bluetooth (UCBT: Bluetooth Extension) as a basis for our model. The project will involve analysing the inquiry packet interference based on the analytical model for single inquiring node interference and to multiple inquiry nodes interference. This should help identify potential solutions for any issues that we across with and attempt to improve the points.

Analysis of a Smart Device Game Protocol

Presentation slides, demo slides, and final report (PDF files).

Abstract:
For decades, multiplayer online games have been used throughout the world as a way of connecting with others and entertaining oneself. Many of these video games rely on a game server to authoritatively determine the source of events. Unfortunately, due to the unpredictable nature of computer networks, these games suffer from packet loss, latency, and jitter. Our project consists of creating a game server with multiple clients and examining the effect this type of traffic has on the network and player quality of service.

Evaluation and Comparison of Wired VoIP Systems to VoWLAN

Presentation slides, demo slides, and final report (PDF files).

Abstract:
VoWLAN is essentially a VoIP system implemented over Wi-Fi, which offers a significantly extended operational range. However, the extension presents trade-offs in stability, such as packet drop rate and additional delays. This project will simulate the performance of voice communication over wired connections to its Wi-Fi counterpart using ns-2, in areas such as operational stability and operational range.

QoS Analysis of Wireless Ad-Hoc Network Routing Protocols

Presentation slides, demo slides, and final report (PDF files).

Abstract:
Wireless ad hoc networks are decentralized communication networks.That is they do not require deployment of distribution bases such as routers and the nodes can establish communication links dynamically among themselves. Self-organized and self-restoring ability of these networks makes them suitable for situations in which rapid configuration and deployment of communication in remote or dangerous environment is required. Wireless ad hoc networks are also well suited for providing mobile communication because they can adapt to rapid changes in the network topology. A given routing protocol plays an important role in timely and reliable transfer of information for a respective network. As you might expect the dynamic nature of ad hoc networks poses a great challenge in design of an optimal routing protocol hence it has been a devoted research topic in engineering and mathematics. This paper will present simulation and comparison of OSPFv3, TORA and GRP using OPNET for a small discretely changing network topology. Our measure of quality of service will be average packet delay and routing discovery time.
