QoS based Security Architecture for Software- Defined Wireless Sensor Networking

An innovative QoS based security architecture for software-defined wireless sensor networking is developed in this paper. Conventional networks are constrained by hardware limitations and rigid architectural design, limiting research and innovation. Software-Defined Networking (SDN) is a networking breakthrough that allows administrators to control and customize their entire network from a central location. SDN makes network management more manageable and more effective. SDN model can deliver versatile routing and help the various communication patterns found in Wireless Sensor Networks (WSN). However, adopting this model to resource- constrained networks is difficult, particularly when security services are required. Current Software-Defined Networking- based Wireless Sensor Networks (SDN-WSN) methods have developed over time to meet resource-constrained needs. In this paper, the authors have discussed security architecture, its challenges and solutions. Further, the comparative analysis of various security algorithms (SEC-SDWSN, Genetic, Routing optimization for cross-domain preservation (ROCDP)) in SDN- WSN is carried out. The SEC-SDWSN achieved the better results based on the Quality of Service (QoS) metrics (packet delivery ratio, data transmission, response time and energy consumed parameters) which shows packet delivery ratio in SEC-SDWSN is 4\% better than Genetic and ROCDP; data transmission rate in SEC-SDWSN is 15Kbps better than Genetic; and response time in SEC-SDWSN is 5\% better than Genetic. Therefore, an original contribution to the literature and practices of network security architecture is made in this paper by developing an innovative QoS based security architecture for software-defined wireless sensor networking.
