On the Feasibilty of Video Gaming on Demand in WLAN/WiMAX

Presentation slides and final report (PDF files).

Abstract:
Have you ever hoped that you could play video games on your computer or laptop without actually buying or downloading the game? Wouldn't it be nice if you could play all the new video games on your old computer with high-speed Internet? In this project, we will find out if that is possible.
With high-speed Internet connection, video gaming experience could be delivered to your computer as if you owned the game and are executing it on your computer. Instead, a server located in the cloud stores the game and execute the gameplay based on your commands, and returns a sequence of video frames to your monitor.
Using OPNET tools for simulation, we will investigate the feasibility of this approach, which could change the entire video gaming industry in the future!
Stay tuned.

OPNET Simulation of IEEE 802.11(WiFi) and IEEE 802.16(WiMax) in a small area

Presentation slides and final report (PDF files).

Abstract:
In the past few years the Wireless Local Area Network (WLAN) has been the most popular choice of communication amongst users. WLAN, which is based on the IEEE 802.11 standard, also known as Wireless Fidelity (WiFi), offers mobility and flexibility with a relatively low cost to users. In addition, wireless technology is providing easier internet access to areas that are too difficult and expensive to reach with traditional wired infrastructure. IEEE 802.16, also known as Worldwide Interoperability for Microwave Access (WiMAX), is another standard with similar general principles as WiFi with the main advantages being it covers a larger area and has a higher data rate. Comparing WiFi and WiMAX under optimal conditions, the fastest WiFi connection is 54 megabits/second while WiMAX is about 70 megabits/second. WiFi has a range of about 30 meters and WiMAX can cover up to 50 kilometers. Figure 1 shows a comparison of WiMAX coverage versus WiFi coverage.

WiMax Networks Simulations Using OPNET Simulator

Presentation slides and final report (PDF files).

Abstract:
WiMAX stands for Worldwide Interoperability for Microwave Access. It is a telecommunication technology which provides wireless transmission. It provides access to Internet and other portable devices. It has a transmission speed of 10 Mbps.The name WiMAX was introduced by WiMAX Forum in 2001.It is an alternative approach to deliver content over cable and other links at .last mile.(which is from a communication provider to a customer). I plan to use Will Hrudey.s Model to find the WiMAX parameters such as transmitting power, antenna gain, channel bandwidth and incorporate audio streams.

Simulation and Performance Analysis of AD AODV Routing Protocols Using OPNET

Presentation slides and final report (PDF files).

Abstract:
A mobile ad-hoc network is a collection of wireless nodes that makes an infrastructure-less multihop autonomous system. Mobile ad-hoc network routing protocols are divided into three groups of reactive routing, proactive routing, and hybrid routing based on their method for acquiring information of other nodes. Ad-Hoc On-Demand Distance Vector (AODV) routing protocol is a reactive protocol that start searching for destination node whenever it needs to send any information toward it. Unlike reactive routing protocols, in proactive routing protocols nodes send their routing table periodically, and hence they have a fresh route to every node whenever it is needed without any delay. Although reactive routing protocols cause a long delay for searching nodes before sending data, they make less congestion versus proactive routing protocols, and hence they have better scalability than proactive routing protocols.
