A Study of FTL Schemes for an Embedded System Based Virtual Fence

Abstract

An embedded system based virtual fence can consist of autonomous sensors to gather environmental information such as temperature, sound, GPS, etc. The nodes that comprise the virtual fence communicates with a base station, whereby the nodes send data that is mesured in the environment of interest to the base station. The neasured data from the node incur considerable I/O such that these writes of small-sized data can limit the performance of a hard disk based base station. We consider the use of an SSD instead of a hard disk. In so doing, in order to ascertain what FTL is appropriate for our environment, in this paper, a series of experiments are conducted and reported for a particular set of FTLs.
