Effects of Forward Error Correction (FEC) on SURAN (Survivable, Adaptive Networks) Protocol

Abstract

This paper discusses effects of using forward error correction (FEC) in the Low-Cost Packet Radio (LPR) on the Survivable, Adaptive Networks (SURAN) protocol operating in the LPR. As we look at the FEC effects, we note that other than the obvious benefit of being able to reclaim otherwise mangled packets there are some implications to the throughput and delay of the network at the link level. Certainly, the fact that otherwise demolished packets are now valuable will increase throughput and decrease delay. The fact that encoded packets require more time to transmit decreases throughput and increases delay. And certainly the processes of encoding and decoding take time. For the purposes of this paper, we will assume that the decision to use FEC has already been made manually or according to some algorithm and deal with the impacts on the SURAP algorithms and suggest possible approaches to handling them.
