Reliability research of wireless sensor network node

摘要

In this paper, it proposes a new energy-efficient, reliable topological clustering algorithm (ERCTNA), which analysis the reliability of wireless sensor networks at the present stage factors and improve the original LEACH protocol. ERCTNA algorithm can balance the cluster head of energy load and increase the reliability of the network topology through setting up auxiliary cluster head node and optimizing information transfer mode. This model improves the traditional long-distance communication in wireless sensor networks to bring the energy of the excessive wear and tear issues, effectively extending the life cycle of the entire network to improve the reliability of wireless sensor networks.
