3.2.7. HEHO

Strumberger et al. [120] developed improved hybrid EHO, named HEHO, to solve the wireless sensor network localization problem. The limit control parameter from the ABC algorithm was incorporated into EHO to control the process of diversification. The usefulness of HEHO was demonstrated using different sizes of sensor networks from 25 to 150 target nodes. Based on the results, the HEHO approach was able to obtain more consistent and accurate locations of the unknown target nodes than other approaches.
