Some results on two forms of erasure-correction coding for packet radio networks

We present some preliminary results from our investigation of two forms of erasure-correction coding, fountain coding and network coding, when they are employed for file transfers in a distributed packet radio network. The radios adapt the modulation and channel coding of the transmitted signals in response to variations in fading on the links of the network. The control information for the adaptive transmission protocol is provided by simple statistics that are derived in the demodulators and decoders of the radio receivers.
