Survey on fault tolerant technology of network layer in wireless sensor networks

Fault tolerance can improve the stability and reliability of wireless sensor networks. It is a key technology in wireless sensor networks. Fault tolerance in network layer and collaborative optimization among the cross layers are the important research content of the network's fault tolerance. The work was mainly to summarize the research of fault tolerance in network layer. The fault-tolerant technologies in network layer mainly included multipath routing transmission mechanism, erasure encoding/network coding mechanism, retransmission mechanism, collaborative optimization among the cross layers, bionic intelligent fault tolerance and so on. In the end, this paper discussed the research trends of the fault tolerance in network layer.
