The main aim of this approach is to merge the good feature of centralized and distributed controller approach and ensure better scalability, availability and performance. Application Layer: At this layer, application developers develop different kinds of applications such as load balancing, sensor scheduling, sensor allocation, routing, security etc. SDWSN paradigm provides flexibility at the application layer to customize data aggregation and gathering without worrying about the required changes in the physical nodes. This feature simplifies the process of developing a new application at the application plane. ADVANTAGES OF SDN PARADIGM IN WIRELESS SENSOR NETWORK The main aim of software defined wireless sensor network (SDWSN) is to provide flexibility by the virtue of decoupling of data and control plane. SDWSN provides following advantages in terms of energy saving, efficient network management and control, efficient and scalable localization, routing, mobility and security features. Energy Saving: Sensor node is generally an energy constraint device that is operated by the limited energy source i.e. by using two AA batteries. Energy saving is a research challenge in the design and development of protocols for WSNs. Since in SDWSN, most of the energy consuming functionalities are performed in the SDN controllers at the control plane which has no scarcity of energy resources. Thus, SDWSN paradigm provides energy efficient operations and could enhance the network lifetime of WSNs. In (Wang, 2016), the authors have proposed a sleep scheduling protocols for SDWSN which provides energy efficient duly cycling for the nodes. Efficient Network Management and Control: SDN paradigm provides an efficient and flexible approach for management and control of a large scale WSNs. This flexibility comes by the separa
