Research:

Mobile wireless networking is experiencing a tremendous rate of growth. Many traditional wireline based applicationsare going wireless. Among other issues, one core issue that needs to be addressed for the success of future mobilewireless communications is energy-efficient wireless networking. Currently, the re-chargeable battery energy capacityof most mobile devices is limited due to a variety of reasons. It is also known that the rate at which battery technology isprogressing is rather slow compared to the advances in wireless technology and applications. Therefore, it is importantto optimize the networking algorithms, protocols and parameters for energy efficiency. Especially, this may be essentialto support next generation high speed wireless networking.In this project we proposed use theory and simulations to investigate the following:

Energy-efficient link and MAC layer protocols for time-varying wireless links. Stochastic control of the trade-offbetween communication versus computation energy.
New probability based MAC protocols that attempt toschedule users such that energy is minimized
Stochastic control algorithms that react to the bursty nature of traffic and link errors.
