Abstract: Multipath routing has been considered in the literature to provide bandwidth aggregation for high data rate applications. Because of the phenomena of inter-path interference in wireless networks, the overall throughput is far from being the summation of the provided ones by the different paths individually. One promising solution to this problem is to make use of interference aware metrics to build multiple paths such that the inter-path interference is minimised. In this work, we are interested in assessing the impact of a set of interference aware metrics on the performance of incremental multipath routing in Wireless Sensor Networks (WSN). Incremental multipath routing builds one path per request/reply session and hence is more suitable to be combined to interference aware metrics. We review, implement and evaluate both active and passive monitoring metrics and show that for constrained networks such as WSNs, the latter are more adapted. Additionally, we show that within the passive monitoring metrics, the best one is not necessarily the most expensive to measure.
