Research on the tenacity survivability of wireless sensor networks

Nodes of wireless sensor networks due to environmental influences and deliberate attacks by nodes in the network, nodes of wireless sensor network are prone to death. In this paper, based on the idea of algorithm fusion, this paper proposes a research method for survivability of wireless sensor networks based on tenacity. A hybrid algorithm based on simulated annealing algorithm and particle swarm optimization algorithm is used to calculate the value of the tenacity of the network node. The optimized algorithm reduces the time and complexity of calculating tenacity. In this paper, the wireless sensor network is simulated and verified. The experimental results demonstrate the feasibility of evaluating the survivability of wireless sensor networks. The proposed method can effectively improve network lifetime and data transmission capability.
