Dynamic Wireless Network Based on Open Physical Layer.

摘要

The goal of this project is to develop new interface to the physical layer, which is more suitable for the use of dynamic wireless networks. Our goal is to explore the formulations that gives a new measure of information, both in terms of how difficult it is to transmit such information and in terms of how valuable it is when received. While traditionally, the amount of information is universally measured in number of 'bits'. Such formulation is particularly suitable when long block codes are used, and the average per unit time rates of information flows are of interests. In dynamic communications, our main observation is that in fact a metric that does not require averaging over asymptotically long period of time is much more meaningful in practice. Moreover, one cannot always think of information as perfectly decoded bits, but rather has to understand how valuable a piece of 'soft' information is. That is, when we cannot guarantee reliable decoding of the message, one still has to efficiently process the message, in order that efficiently communication over the entire network is achieved.
