SYSTEM AND METHOD OF WSN-ASSISTED LOCATION SERVICES

摘要

A method of providing wireless sensor network (WSN)-assisted positioning services comprises receiving a positioning service request from a client, the positioning request identifying at least one target UE located within a WSN comprising a plurality of sensor nodes; transmitting a listening request message to the at least one target UE; receiving a positioning request message from the at least one target UE, the positioning request message containing addresses and received signal quality indicators of at least four WSN sensor nodes acquired by the at least one target UE; computing a 3-D position of the at least one target UE using the addresses and received signal quality indicators of the at least four WSN sensor nodes; and transmitting the 3-D position of the at least one target UE to the client.
