One-way packet delay at different sending intervals. a One packet per node every 10 s. b One packet per node every 20 s. c One packet per node every 60 s. d One packet per node every 120 s. Those figures show the analysis of the packet delay at different data sending intervals. Those results were depending on the number of hops between the sensors. This analysis is important in a disaster monitoring to know the time delay to get the information and act as quickly as possible depending on the sensors data information
