Projects
Personal Networks

Using handheld devices such as cellular phones and smart phones for personal entertainment has become commonplace in today’s lifestyle. Virtually all of these devices are equipped with one or more wireless technologies such as WiFi, Bluetooth, 3G, etc that can be used to distribute entertainment contents such as music and movie clips. Mobile users can download content from the opportunistically available infrastructure (e.g., Digital Billboards) as well as direct Peer-to-Peer (P2P) exchanges. The goal of this project is to design an efficient P2P content distribution protocol.

Project Goals

• Understand the inter-interoperability of various wireless technologies for content distribution
• Understand the characteristics of Bluetooth protocol operations, ranging from peer discovery to data downloading in dynamic mobile urban environments
• Analyze the Bluetooth protocol operations mathematically
• Develop performance enhancement techniques for Bluetooth-based content distribution
• Develop a testbed to analyze the real-word performance of Bluetooth-based content distribution.
