Our monitoring equipment is scattered in the field on large distances and communicates using radio. On different occasions we are losing the data due to different reasons. One of the reasons is lack of power but there are also cases when the equipment is running but we are losing the communication. In order to identify the reason why the data is not coming I would like to perform the following analysis – could you please guide me how would you approach and solve this problem:
How to identify that there is data gap for a number of locations, or in other words, in case some locations are not sending the data I would like to know the list of those.
It is important to select those locations which are not sending data from certain point in time (with acceptable time margin e.g. 5 minutes) – so in case there is another location which is not sending the data later or earlier then it should not be included in this group.
Basically what I am trying to achieve (not sure if this is right approach) is to decide on the status of one element based on factors (attribute values) of other elements (siblings), or (different approach) to compare and select certain event frames then to update element attributes for those specific even frames.
