The research on Wireless Sensor Network node positioning based on DV-hop algorithm and cuckoo searching algorithm

摘要

The sensor node positioning is the important technology in Wireless Sensor Network. DV-Hop algorithm has the accumulative errors during the sensor positioning procedure. In order to increase the DV-Hop positioning precisions, this paper first corrects the distance of the average hop in DV-Hop algorithm, then introduces cuckoo searching algorithm to optimize the sensor node positioning errors, and finally applies simulation experiment to test the performance. The simulation experiment illustrates the proposed algorithm needs extra hardware support in order to increase the Sensor positioning precisions compared to DV-Hop algorithm. Even with fewer anchor nodes,the proposed algorithm can obtain ideal positioning results with high practical value.
