Abstract Crucial node decision plays an important role during the network survivability study. Taking into account the node energy is limited, this study consider both the remaining life of the network and the added value of network energy consumption due to the node failure. A Critical Node Decision algorithm Based on Energy (CNDBE) is proposed, the problem which crucial node decision algorithm based on energy is solved. Simulation results show that, when the node which is decided by crucial node decision algorithm based on energy is protected, the network with CNDBE has a better survivability performance and has a longer lifetime when compared with Shortest Path Tree (SPT) and Energy–Critical Node Aware Spanning Tree for sensor networks (ENCAST).
