Exploring traffic for P2P file sharing protocol using OPNET

Presentation slides and final report (PDF files).

Abstract:
P2P file sharing protocol is widely used by most torrent engines available for downloading data. Most torrent engines are based on the following phenomenon: more seeds (peers) there are, faster is the response time for the download for the client (end user). The whole idea of using P2P network is instead of downloading a file from a single source, the end user can download it from multiple sources. We will be implementing the ABR scheme for this project, i.e. Available Bit Rate as there will be no limit on the number of users and response time for the download will be directly proportional to the number of peers uploading certain parts of file.

Comparison and Analysis of FIFO, PQ, and WFQ Queuing Disciplines in OPNET

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

Abstract:
With recent advancements in greater network speeds and higher bandwidths, the online use of applications that support services such as VoIP, video conferencing, and file sharing (FTP) have become more prevalent. While some applications such as web browsing (HTTP), email, and FTP are insensitive to the delay of transmitted information, VoIP and video conferencing are not. Queuing disciplines are therefore implemented in routers to govern, control, sort, and to prioritize packets in the buffers prior to their transmission. FIFO, PQ, and WFQ queuing are implemented in OPNET and various parameters including but not limited to: average queuing delay, average packet drop rate, MOS, jitter, and average end-to-end delay are studied and comparison of these parameters is made for the three queuing disciplines studied.

Analysis of Quality of Service (QoS) on Broadband over Powerline and Power Line Communication Networksvia OPNET 14.0

Presentation slides and final report (PDF files).

Abstract:
The increasing use of Broadband over Power Lines (BPL) using Power Line Communication (PLC) technology to deliver broadband service to homes and businesses indicates great promise as a universal broadband s olution that would offer a viable alternative to cable, digital subscriber line (DSL), fibre optic, and wireless broadband solutions. BPL modems handle the work load of retrieving packet data out of an elec tric current. These modems are capable of handling powerline noise on a wide spectrum and are mandated to be designed to notch out frequencies on which radio interference with short-wave and ham radios occu rs. In reality, the orthogonal frequency-division multiplexing (OFDM) modulation techniques are not alw ays implemented. In addition, deployment of BPL has illustrated the primary challenge of power lines be ing inherently a very noisy environment. Therefore, the system must be designed to deal with these sign al disruptions and work around them. For this project, we plan to use OPNET to analyze the quality of s ervice, the performance signal strength, data loss on different operating frequencies, and reactance to background noise of the BPL and PLC network.

Voice over Internet Protocol (VoIP) over 3G network

Presentation slides and final report (PDF files).

Abstract:
Voice over Internet Protocol (VoIP) is a communication technology for voice and multimedia transmission over Internet Protocol (IP) while 3G network is the third generation for mobile telecommunications. With the increasing popularity of information transferal, VoIP will be widely in use. As customers' desire nowadays for mobility and flexibility, long distance data transfer with the use of smart phones with 3G network are highly desirable. Analysis of Quality of Service (QoS) on long distance data transfer (or in particular, video conferences) between two locations with VoIP over 3G network will be performed. Performance on any parameters which might affect the overall quality will be discussed using the network simulator, OPNET.

Analysis of Live Video Streaming Over Bittorrent Peer-to-Peer Protocol

Presentation slides and final report (PDF files).

Abstract:
Today Bittorrent protocol is widely popular for transfer of files. Because Bittorrent is a peer-to-peer network there is not one central server that files exist on. This means people share files with each other and each node (device connected to the internet) owns a specific chunk of the file. This requires the file data to be of a fixed size and known before transf er is started, so that the neccessary parts of the file are downloaded without the need of them being in order. Because live streaming does n ot provide any of these information, more policies are required to allow Bittorrent to provide live streaming of video. Research shows that the change required is very minimal and costly. In this project we will examin these changes and analyze how Bittorrent handles live video stre am. Our concerns are mainly: stream speed vs. user group size, and stream buffering speed vs. video quality.

Video Streaming over the 802.11g and the 802.11n WLAN Technologies

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

Abstract:
The goal of this project is to simulate video streaming over the 802.11g and the 802.11n WLAN. In gener al, 802.11g is a third modulation standard of carrying out wireless local area network (WLAN) computer communication in the 2.4 GHz frequency bands, which operates at a maximum physical layer bit rate of 10 8 Mbit/s. 802.11n is a recent amendment which improves the 802.11g standard by adding multiple-input mu ltiple-output antennas (MIMO), which can operate on both the 2.4GHz and the 5 GHz bands at a maximum ph ysical layer bit rate up to 600 Mbit/s. In the practical limited bandwidth, I will analyze their bandwi dth usage which may experience the delay of video streaming or an overload in data traffic when they ar e implementing concurrently with other applications such as downloading files. For effective video stre aming through the WLAN, I am going to use some popular compressed multimedia formats such as MPEG-4(H.2 64 for video) and AAC (for audio).Also, I will test 720P and 1080P HDTV AVC video format on both standa rd of WLAN to figure out their ability for future intensive video streaming. Moreover, I will examine s pecific results such as throughput and pack loss of the 802.11g and the 802.11n WLAN on multi-user¡¯s v ideo streaming.

Video Streaming over WiMAX

Presentation slides and final report (PDF files).

Abstract:
WiMax is IEEE Standard 802.16; a wireless technology that uses radio waves to transmit data. It is similar to Wifi technology, but has advantages such as a substantially longer range capability and a faster transfer rate. Because of these advantages, WiMax has the capability to replace DSL wire lines. We will evaluate the performance of streaming video over a WiMax network. Our video will use MPEG compression. Factors to analyse include delay, jitter, and packet loss of the video streaming.

Examining Wireless Mesh Network Routing Protocols Through Simulation

Presentation slides and final report (PDF files).

Abstract:
I will examine mobile ad hoc network routing, specifically the protocols used in wireless mesh networks. Due to the lossy characteristics of wireless links, mobile networks need to dynamically determine which link is optimal for the routing of a particular packet. I hope to simulate the Better Approach to Mesh Ad hoc Networking (B.A.T.M.A.N.), and compare the results to similar scenarios using the Optimized Link State Routing Protocol (O.L.S.R. - RFC 3626). This comparison is particularly valuable since the B.A.T.M.A.N. protocol was designed to replace O.L.S.R. in wireless mesh networks.

Improved Ant Routing for Wireless Ad-Hoc Mesh Networks

Presentation slides and final report (PDF files).

Abstract:
When establishing conventional wired network system is difficult or non-existent, an ad-hoc wireless network can be used to set up a temporary mean of communication by having nodes behave as hosts and routers. This makes ad-hoc wireless network suitable for rapid deployment in emergencies, but much more susceptible to changes in network configurations and routing decisions. In this project, a biology-inspired ant routing algorithm with GPS assisted location awareness is used to reduce routing overhead and to improve convergence compared to ant routing without location awareness.

Analysis of BitTorrent

Presentation slides and final report (PDF files).

Abstract:
BitTorrent is a peer to peer file sharing protocol used for distributing large amounts of data and it is widely used these days.Moreover, the BitTorrent protocol can distribute a large file without the heavy load on the source computer and network.Rather than downloading a file from a single source,the bitTorrent protocol allows different users to join a swarm of hosts to download and upload sources from each other.In this project, we will analyze the traffic load and performance change of the network when multiple sources are shared on a personal computer.
