Abstract

Providing current transmission conditions from a data-link layer (or below) to an application layer, determining coding schemes, with différent coding schemes applied for encoding the data as determined by a threshold of transmission conditions, and transmitting the encoded data. The threshold of transmission conditions may correspond to the existing signal to noise ratio (SNR) in a transmission médium. One of the coding schemes may be a cross layer unequal error protection (UEP) coding scheme. The cross layer UEP may include adding error coding to both of the header and data packet portions of the data if the transmission conditions (eg. like the SNR) are below the threshold of transmission conditions.
