Study on a Zigbee-based weight location algorithm

摘要

As classic algorithms occupy a lot of system resources and location effectiveness can be affected in the case of information loss at some nodes, this paper proposes a Zigbee-based weight algorithm, combined with range-based and range-free localization. The location of unknown nodes is obtained according to the location of known nodes and the received signal strength indicator (RSSI) of unknown nodes. Tests show that the weight algorithm has the advantages of better reliability, real time and accuracy etc.
