Aiming at problem that traditional indoor positioning algorithm cannot eliminate impacts of nodes dynamically moving on position

design a dynamic cross-layer data queue management approach based on priority.Analyze on positioning method and delay tolerant issues of traditional location fingerprinting

and implement priority data queue management mechanism between data link layer and MAC layer. Experimental results show that the indoor positioning method which integrates this mechanisms has better positioning precision

data transmission rate and self-adaptivity than traditional positioning methods.
