摘要
Aiming at all existing energy-hole repair algorithms for wireless sensor network must execute repeatedly in every round, energy-hole repair algorithm based on cluster (EHRA) is proposed in this paper. Before any common node is about to die because of exhaustion of energy, it sends failure message to its cluster head, and the cluster head activates suitable redundant node which is in the sensing range of failure node and has the most energyhole boundary nodes as neighbor nodes. Simulations present that the performance of EHRA is related to sensing radius of nodes and the size of cluster, while EHRA has an advantage over 3MeSH in coverage keeping, energy consumption and time consumption. © 2013 Academy Publisher.
