Multipath routing holds a great potential to enhance transmission reliability in Industrial Wireless Sensor Networks (IWSN). This may be heavily impeded by the phenomena of interpath interference especially for high data rate applications. The aim of this paper is to assess the impact of a set of interference aware metrics on the performance of an iterative multipath routing where paths are built one after the other. A path is chosen based on its estimated interference with already built ones. We consider both active and passive metrics and show that the latter are more preferred in the context of IWSN characterized by their limited resources. Among passive monitoring metrics, we show that the best metric is not necessarily the one that is the most costly to estimate.
