“…Reference [19] addressed protection when failures are intermittent, or if packets are lost. This paper introduced a coding strategy for protecting against an average number of failures over a certain period of time, rather than a fixed maximum number of failures.…”

This paper serves as a tutorial lecture on the use of network coding to provide resource efficient, and agile proactive protection. Network coding, which was introduced in [1], allows intermediate network nodes to form linear combinations of packets received on different input links. The use of network coding results in capacity enhancement. This capacity enhancement is used to provide protection channels which are used to carry combinations of redundant data, and are solved by the receivers in order to recover data lost due to network failures.The paper starts by addressing network coding-based protection of bidirectional unicast connections, and explains the use p-Cycles to carry linear combinations of the redundant data units. The paper also discusses an earlier protection strategy which is based on diversity coding, in which the linear combinations are formed at special nodes, including sources, and is used to protect unidirectional connections. A generalized network coding-based protection which uses a tree to carry the linear combinations will be presented. Protection of multicast connections using network coding is also explained

“…The deterministic LNC scheme proposed in Section 3 achieves the network throughput N = L − f exp (L denotes the number of edge-disjoint paths between the source and the destination and f exp is the expected number of path failures per time slot), while the LNC scheme proposed in [21] does not ensure that the network throughput can achieve N = L − f exp . Therefore, the deterministic LNC scheme proposed in this paper can achieve higher network throughput than our previous work in [21]. Moreover, in this paper, we also investigate the potential of standard random LNC to thwart path failures in WSNs and analyze the lower bound of the probability that a random LNC can provide reliable communication.…”

We address the modeling and design of linear network coding (LNC) for reliable communication against multiple failures in wireless sensor networks (WSNs). To fulfill the objective, we design a deterministic LNC scheme RDLC based on the average number of path failures simultaneously happening in the network other than the maximum number of path failures. The scheme can significantly improve the network throughput comparing with the traditional approaches. In our study, we also investigate the potential of random linear code RRLC for providing reliable communication in WSNs and prove the low bound of the probability that the RRLC can provide the reliable communication. Finally, extensive simulation experiments have been conducted, and the results demonstrate the effectiveness of the proposed LNC schemes.
