Research on wireless sensor networks fault-tolerant coverage algorithm base on particle swarm optimization
Peng Li, Kai Liu, Gang Liu · 2010
Wireless sensor network fault-tolerant coverage algorithm is after the network covered self-organization, and one or some of the nodes got failure to capture the enemy or to play its role. In some occasions, this will cause tremendous impact on the entire network. Fault coverage uses particle swarm optimization algorithm to ensure network connectivity in the circumstances, and just use the nodes in the fault region to finish self-organization coverage, so that not only improve the network coverage, but also to ensure the network connectivity. Because of the nodes out of the fault region did not participate in self-organized movement, it can save a lot of energy, and increase network lifetime. The experiments show a good result.
