“ Four Bit Wireless Link Estimation ” by Rodrigo Fonseca, Omprakash Gnawali, Kyle Jamieson, and Philip Levis. In Proceedings of the Sixth Workshop on Hot Topics in Networks (HotNets VI) , 2007.
"We consider the problem of estimating link quality in an ad-hoc wireless mesh. We argue that estimating links well requires combining information from the network, link, and physical layers. We propose narrow, protocol-independent interfaces for the layers, which in total provide four bits of information: 1 from the physical layer, 1 from the link layer, and 2 from the network layer. We present a link estimator design with these interfaces that reduces packet delivery costs by up to 44% over current approaches and maintains a 99% delivery ratio over large, multihop testbeds.
