Cross-layer Design of Wireless Ad-hoc Networks: Is it Better to be Robust, Quick, or Responsive?



Wireless ad-hoc networks will enable many new and exciting applications such as entertainment networks, sensor networks, smart homes and buildings, and automated highways and factories. These systems will have enormous variation in their device capabilities, network requirements, and application demands, giving rise to significant wireless network design challenges. These challenges are best addressed using a cross-layer design of the network protocol stack. In particular, techniques for multiplexing to provide high data rates, diversity to improve robustness, and adaptivity to improve performance and efficiency extend across all layers of the protocol stack. In this talk we discuss exploiting these cross-layer techniques in three specific ad hoc wireless network applications: video transmission, energy-constrained sensor networks, and distributed control. Performance results for each application will be presented that demonstrate significant improvements through cross-layer design.


Andrea Goldsmith received the B.S., M.S., and Ph.D. degrees in electrical engineering from U.C. Berkeley in 1986, 1991, and 1994, respectively. She is currently an associate professor of Electrical Engineering at Stanford, and previously held positions at Caltech, AT&T Bell Laboratories, and Maxim Technologies.

Dr. Goldsmith is a Fellow of the IEEE, holds the Bredt Faculty Development Scholar Chair at Stanford, and is the recipient of several awards including the National Academy of Engineering Gilbreth Lectureship, the Alfred P. Sloan Fellowship, the NSF CAREER Award, the ONR Young Investigator Award, and the David Griep Memorial Prize from U.C. Berkeley.
