Analytics DD WRT

Good evening, I'm doing a college project, where modify the firmware of TP-Link TL-WR740N router, installing the DD WRT, using a simple scrip it sends MAC logs to my server where separate cell mac and thereby create a report of permanency, saying permanency time. With this log sent I can not know the distance. I wonder you can create a scrip where I can change my router with DD WRT and make a simple configuration, where I put the router name and define the folder where the router make sending this log of captured cell and the distance of each mec adress, it sent every minute, so I can put it all together in a database to make this survey frequcencia in a control panel that I am developing. Thank you so much!
