Executive Summary

In this paper, the authors evaluate the performance of Random Linear Network Coding (RLNC) in low data rate indoor sensor applications operating in the ISM frequency band. They also investigate the results of its synergy with Forward Error Correction (FEC) codes at the PHY-layer in a Joint Channel-Network Coding (JCNC) scheme. RLNC is an emerging coding technique which can be used as a packet-level erasure code, usually implemented at the network layer, which increases data reliability against channel fading and severe interference, while FEC codes are mainly used for correction of random bit errors within a received packet.
