Efficient Error Estimating Coding: Feasibility and Applications
ABSTRACT
Motivated by recent emerging systems that can leverage
partially correct packets in wireless networks; this paper
proposes the novel concept of error estimating coding
(EEC). Without correcting the errors in the packet, EEC
enables the receiver of the packet to estimate the
packet’s bit error rate, which is perhaps the most
important meta-information of a partially correct packet.
Our EEC design provides provable estimation quality
with rather low redundancy and computational overhead.
To demonstrate the utility of EEC, we exploit and
implement EEC in two wireless network applications,
Wi-Fi rate adaptation and real-time video streaming. Our
real-world experiments show that these applications can
significantly benefit from EEC.
