2010 Poster Sessions : Bandwidth Estimation and Rate Control for Heterogeneous Wireless Networks

Student Name : Dimitrios Tsamis
Advisor : Nicholas Bambos
Research Areas: Information Systems
Modern cellphones can connect to multiple types of wireless networks, which vary wildly in their characteristics. Moreover, wireless networks have by their nature fluctuating capacity. These realities create difficulties for smartphone applications that depend on internet access. In this work we develop a new method to estimate the available bandwidth and also a lightweight framework to make short-term predictions on it. Real world data were collected on three different networks. To highlight the value of our framework, we also developed a couple of rate control algorithms that exploit the bandwidth predictions to provide better results.

Dimitrios Tsamis is a 4th year PhD student working with Nick Bambos in the Information Systems Lab at Stanford University. He received his Diploma in Electrical and Computer Engineering from the National Technical University of Athens, Greece in 2006. Since then he has been working on such applications on wireless networks as power control, bandwidth estimation and rate control. Lately he is investigating applications in health-care systems.
