Abstract: In practical applications, the connectivity repair simulation of wireless sensor networks is quite different from the actual network performance. In view of this difference, we simulate a cluster head replacement strategy. Specifically, the cluster head node collects perceptual packet sent to the aggregation node. After the cluster head node fades, the network starts performing repair action, and the repair node moves to the position of the cluster head node to replace the cluster head. Further, the cluster wireless sensor network is modelled and the network repair process after node failure is simulated by OPNET software. Network connection repair processes in 2D plane scenarios and 3D terrain scenarios are also compared. The experimental results show that the strategy of the cluster head can complete the repair of network connectivity, and the 3D terrain field centralised node receives power higher than in the 2D planar scene.
