On the method of group polling upon the independent activity of sensors in unsynchronized wireless monitoring networks

P. 266-278.

It is considered the model of large monitoring networks with working independently sensors for an alarm signalization. Outlined in the previous papers the method of group polling for alarming sensors identification used the time synchronization. The last condition is very strong for vide distributed monitoring networks. Recently proposed method of group polling for the alarming sensors identification in unsynchronized wireless monitoring network is investigated. Based on numerical simulations, it is found that the group polling method may be effective for unsynchronized networks with thousands or more sensors and the decoding algorithm may be realized on-time using parallel executions. Recommended number of the code signal repetitions is proposed.
