Error recovery service for IEEE 802.11B protocols via adaptive forward error correction and dynamic packet sizing

We develop a service that allows that current IEEE 802.11b MAC protocol to perform dynamic packet sizing and forward error correction. Our service, called ERSMAC, is designed to allow the deployment of the IEEE 802.11b protocol in industrial environments characterized by high BER and fast time variation. ERSMAC uses a maximum likelihood estimate of the BER to solve for the optimal packet size that maximizes the success probability of …
