A Review of Centalised Localization Algorithms Based on SDN Approach in WSN

The centralized localization of WSN is a significant role due to strong correlation between the location of data origin and sense data aggregation. The technique of Software Defined Network(SDN) support the localization algorithm and consider all network limit and constraints. Previous research finding indicate that a significant enhancement in network performance can be attained by the utilization of SDN controller's network. In order to identify the most effective technique for localizing nodes in Software defined network with highest accuracy and least amount of energy consumption. this research investigates the newly published centralized localization algorithm and examine the simulation result for each approach. Additionally the software defined networking concept and WSNS issues that were resolved by SDWSNs.
