Design and Implementation of WSN Node Applying to Moving Multi-objective Location

As a key aspect of wireless sensor network, wireless location is a research hotspot. Among a lot of locating methods, the one based on RSSI is approved by many a researcher. The principle and algorithms of RSSI locating technology are introduced, a location node is designed and developed with the first SoC ZigBee chip all around the world, and the working process of location engine software is analyzed. The experiment results of testing nodes indicate that nodes can communicate, receive and transmit data successfully between nodes and therefore achieve wireless location.
