400 Cyber-Physical Systems: From Theory to Practice
from some finite fields. Nevertheless, in order for the sink to recover the original information, a
decoding process is required. Thanks to this approach, there are possibilities that there will be NC
schemes such as the stateless NC scheme that can be suitable for networks with unknown or changing
topologies.
16.3.3 NETWORK CODING PROTOCOLS
According to Lima et al. [25], NC protocols can be categorized into the following two main types
of protocols: stateless and state-aware NC-based protocols. This categorization is based on whether
the NC protocol makes use or does not make use of the network state information that includes
information related to the state of the network such as network topology ...
