A Novel Framework for Software Defined Wireless Sensor Networks

A novel framework for software defined Wireless Sensor Networks (SDWSNs) is presented that draws on Software Defined Networking (SDN) concepts and capabilities to enhance control, management, and security, whilst reducing device complexity. These inherent complexities pose significant challenges toward the advancement of ubiquitous sensing and sensory data access through Sensing-as-a- Service (S2aaS) model. Therefore, it is advantageous to utilize SDN to decouple the control and the data forwarding planes and incorporate greater control over dynamic virtualization and approaches to improve the quality of experience. Enhanced algorithms can be applied on improved knowledge of the network conditions that is attainable when SDN is employed. We run simulations based on sensor flow model and provide a comprehensive analysis of the SDWSN framework, architecture and implementation constraints.
