Summary:Wireless sensor network (WSN) are widely used in many different scenarios. The localization information is crucial for the operation of WSN. There are mainly two types of localization algorithms. The Range-based localization algorithm has strict requirements on hardware, thus is expensive to be implemented in practice. The Range-free localization algorithm reduces the hardware cost. However, it can only achieve high accuracy in ideal scenarios. In this paper, we locate unknown nodes by incorporating the advantages of these two types of methods and propose a new algorithm named the RSSI-based DV-hop algorithm (RDV-hop). Our algorithm improves the localization accuracy compared with previous algorithms, which has been demonstrated by the simulating results.
