“…On the other hand, fault diagnosis plays an important role on stable applications maintaining in WSNs. The paper by Xiangrong Xiao, Dewen Hu, Deke Guo, and Kebin Liu entitled ‘IF: isolating fault nodes with mobile scanner’ proposes a novel mechanism isolating fault nodes, that employs the mobile node as a scanner to diagnose the faults in WSNs. The mobile scanner can detect the fault nodes within its communication region by using sniffer.…”
