As wireless sensor networks (WSNs) technologies are becoming more mature and the use of WSNs for different cyber-physical applications are becoming increasingly popular, it is now possible to set up more than one WSN in the same area. However, constant failures may occur in these WSNs, causing a network to be partitioned into several parts. Nodes in the parts without the sink will lose the opportunity to report their data, significantly degrading the performance of the supported cyber physical applications. In this paper, we propose SUSTAIN, a fault tolerance support algorithm that adapts to the network conditions and exploits the nodes in other neighboring networks as relays to resume communication for the faulty network. Our simulation results demonstrate that SUSTAIN increases the average packet delivery ratio in the network sometimes by more than 40% with an affordable amount of delay and cost overhead.
