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

Abstract:

   

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.
