Integrated-services networks are emerging that carry diverse traffic types like voice, video, text and images in an integrated and con-sistent manner using packet-switching. The Internet, phone and cable TV networks are all moving in this direction. Professor Peha is developing algorithms to control the flow of traffic through the network such that respective application performance requirements are met, and congestion effects are minimized. He is also developing complementary pricing mechanisms.
Wireless networks are becoming increasingly important for both voice applications (e.g., telephony) and data applications (e.g., computer communications). Professor Peha is investigating access protocols through which devices can share spectrum efficiently, and mobility management techniques that allow devices to move while communicating. The related policy issues of spectrum management are also addressed.
Professor Peha is investigating models to understand network behavior, including models based in chaos theory. He is developing new simulation and analytic tools.
