In this paper, we explore the viability and possible limitations of a delay-tolerant positioning process for location-based logging. Instead of esti- mating the device position on the device, a delay-tolerant technique stores the radio and Wi-Fi data needed to calculate that position, sends it to a server when appropriate, and it is the server that will calculate the position. This is very suitable for location logging because it supports the generation of fre- quent position registers without incurring in high communication and energy costs. We have conducted a controlled experiment to assess the accuracy of this technique and the results suggest that the accuracy of the positions calcu- lated on the server using this technique is the same as those that can be ob- tained by calculating the position directly on the device.
