An improved algorithm of DV-hop in wireless sensor networks


This paper introduces cuckoo searching algorithm to optimize the sensor node positioning errors after correcting the distance of the average hop in DV-Hop algorithm, then 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. The proposed algorithm can obtain ideal positioning results with high practical value with fewer anchor nodes.
