This data consists of Contiki OS/Cooja simulation files to conduct experiments based on previously obtained diagnostic data from a six-month-long deployment on a construction site, specifically on a new Crossrail Station in Paddington, London. Accompanying these files are the scripts and data used to generate the figures presented in the paper. This research data supports "A Handheld Diagnostic System for 6LoWPAN Networks" which will be published in "13th Wireless On-demand Network systems and Services Conference (WONS 2017)"
