Analysis of Notable Security Issues in SDWSN

Wireless Sensor Networks (WSNs) are network paradigm that are constrained by several challenges such as management of the network, energy consumption, data processing, quality of services (QoS) provisioning, and security. Software-Defined Networking (SDN) emerged as a viable solution to mitigate these inherent challenges yielding SDWSN. SDWSN is gaining momentum and has brought innovation, ease of network management and configuration through network programmability. However, SDWSN is not immune to challenges due to several issues inherited from both the WSN and SDN. Although several research works have been carried out aimed at proffering solutions, there is still more to be done to ensure SDWSN is secure, dependable, and scalable. Therefore, this paper brings together some of the notable issues that needs to be addressed and some of the solutions already proposed or developed. The objective is to get insights into these challenges and provide some solutions. We presented and discussed specifically, the security issues with respect to SDWSN model, threats, attacks, and some of the existing countermeasures.
