Abstract: Internet of things (IOT) has been gained widely attention in recent years. As an emerging research area, IOT is regarded as the extension of information network to the real world. IOT turns to be a crucial growth point in the economic field of China and will play a key role both in the future scientific innovation and social progress. The location of “things〞 nodes is one of the significant features that reflect the status of IOT system. Furthermore, nodes’ location acts a major relevancy with information collecting and related information exchange. In this paper, we focus on the key technologies on the location-awareness for “things〞 nodes in IOT. We introduce localization theory and approaches, which cover the range-based and range-free methods, network cooperative localization and multi-sensor location-aware issues. We offer an overview and for nodes location-awareness by taking various
