Center hyperedge (induced by source paper "network coding based protection strategy against node failures"):
  Abstract: The enormous increase in the usage of communication networks has made protection against node and link failures essential in the deployment of reliable networks. To prevent loss of data due to node failures, a network protection strategy is proposed that aims to withstand such failures. Particularly, a protection strategy against any single node failure is designed for a given network with a set of $n$ disjoint paths between senders and receivers. Network coding and reduced capacity are deployed in this strategy without adding extra working paths to the readily available connection paths. This strategy is based on protection against node failures as protection against multiple link failures. In addition, the encoding and decoding operational aspects of the premeditated protection strategy are demonstrated.
