Field Size of Random Network Coding in Untrustworthy Networks

The authors examine the probability of symbol error and the throughput with random network coding in untrustworthy networks, where the network nodes provide false data purposely or unknowingly and the information transmission is subject to channel error. They show that there exists an optimum field size that maximizes the throughput (bits/channel use) or minimizes the probability of symbol error. They examine how the optimum field size depends on the trustworthiness of node and the number of packets that are combined in untrustworthy network.
