WSN辅助的室内无缝切换系统

s one of fundamental technologies of the internet of things, location aware technology has been widely used in emergency rescue, tracing, intelligent transportation, logistics management and medical care. All of these applications must be supported by seamless location technology with high precision in indoor and outdoor environment. This paper focused on the continual and precise location technology for the large-scale and complex constructions in indoor environment.This paper presents WSN-aided handoff algorithm.It solve seamless handover between different location mode at the border of indoor areas, even the quality of WLAN signal is not good or in this areas not placed APs. Experiment results showed the efficiency of method and verify the performance of the algorithm.
