Security issues, Countermeasures and Dynamic queue scheduling for SDWSN

Traditional Wireless Sensor Networks (WSN) contains collection of sensor nodes to record and monitor environmental conditions for current and future analysis. Challenges and issues in WSNs are no proper network management, limited resources such as limited amount of energy, storage and processing power and more vulnerable to attacks due to open medium. As a solution, new paradigm, Software Defined Networking (SDN) is merged with WSN is called Software Defined Wireless Sensor Network (SDWSN) to provide automated dynamic network management, Low energy consumption, scalability, reliability, flexibility and robustness by separating control intelligence and network devices. However, SDWSN introduces new security challenges due to programmability nature of SDN and communication protocol. This brings a need to discuss about security issues in SDWSN and possible solutions. This paper examines possible vulnerabilities, analysis of severities, countermeasure to those attacks and proposed dynamic scheduling to overcome packet drop and congestion before applying any security mechanism to avoid congestion as misconception as attacks and to increase network performance.
