Internet Access Using Dense Self-Managing Wireless Networks

Опубликовано 7 сентября 2016, 17:19

Wireless networking is becoming the dominant technology for Internet access, resulting in a rapidly growing demand for wireless bandwidth. Meeting these demands requires new wireless techniques that make efficient use of the scarce unlicensed spectrum. In this talk, I will discuss four such techniques: channel aware rate adaptation (Charm), a protocol for opportunistic retransmission (PRO), transmit power and CCA threshold tuning, and the use of directional antennas. I will present the design, implementation, and evaluation of each technique and I will also discuss some common design principles that emerge and some of the fundamental differences between the techniques. Finally, I will briefly describe how we used the CMU wireless network emulator testbed in the evaluation and tuning of some of the protocols.
