Impacts of Duty-Cycle and Radio Irregularity on HCRL Localization in Wireless Sensor Networks

This paper focuses on studying the impacts of two important factors that have been once ignored in localization: 1) duty-cycle of sensor nodes and 2) DOI (degree of irregularity) in radio irregularity. It reveals the fact that a smaller DOI can help to increase the localization accuracy in Distance-Vector (DV) based localization, e.g., HCRL. But, waking up more sensor nodes cannot always help to increase the localization accuracy, which actually is different from our intuitive thinking: more awake nodes can help to increase the HCRL localization accuracy.
