Lightweight localisation approach for WSNs: performance analysis and validation

Abstract

Wireless sensor networks (WSNs) have become very popular in recent years due to their wide applications' spectrum. One of the main issues arising while conceiving with WSNs functionality is the opportunity of developing a proper localisation algorithm that has to be tailored basing on hw/sw nodes limitations. This study proposes a localisation algorithm for WSNs based on received signal strength measurements whose results, although comparable with existing localisation algorithms, proves here to be of practical implementation on devices with very low computational capabilities as well as efficient in real-time usages. Extensive simulations and indoor/outdoor experimental measurements have been performed to verify the effectiveness of the proposed algorithm, taking also into account implementation issues on commercial sensor nodes.
