A review of localization algorithms based on software defined networking approach in wireless sensor network

Abstract

Wireless Sensor Network (WSN) localization is an important challenge, because A strong relationship between aggregation sense data and the location of data's origin. Software Defined Networks (SDN) technique is support localization algorithm and take into account all network's limitations and constraints. By making use of global network knowledge provided by SDN controller, the results of previous studies show that considerable improvement in network performance can be achieved. This paper explores the recently proposed localization algorithms and discusses the simulation results for each method used in Software Defined Wireless Sensor Networks (SDWSN) to find the best way to localized nodes with the highest accuracy and lowest energy consumption. This paper also present Software defined networking paradigm and WSNS challenges which solved by SDWSNs.
