DV-hop localization algorithm with weight-based oriented cuckoo search algorithm

Oriented cuckoo search algorithm (OCS) is a newly proposed variant of cuckoo search algorithm, to avoid the premature convergence, weighted-based oriented cuckoo search (WOCS) is proposed which is a combination of OCS and the standard CS. WOCS achieves a balance between exploration and exploitation. To test the performance, WOCS is incorporated into the methodology of DV-Hop localization algorithm for node localization in wireless sensor networks. The simulation results show that DV-Hop localization with WOCS achieves best positioning accuracy when compared with other two algorithms.
