“…By comparing their differences and similarities, OpenFlow-based SDN provides higher flexibility and control in terms of development, administration, and network management [3,9]. It is not surprised that OpenFlow-based SDN paradigm has been applied to a number of proposed SDWSN architecture [2,[10][11][12][13][14][15].…”

“…The position of the controller significantly impacts the SDWSN performance in terms of energy consumption, scalability and reliability. Most of SDWSN architectures are proposed with both centralized [11,14,16,18,20] and distributed control plane [10,12,15,21,22]. The two approaches result in differences in position and function of the SDWSN controller and SDWSN nodes ( Table I).…”

Abstract-Wireless sensor networks (WSNs) are essential elements of the Internet of Things ecosystem, as such, they encounter numerous IoT challenging architectural, management and application issues. These include inflexible control, manual configuration and management of sensor nodes, difficulty in an orchestration of resources, and virtualizing sensor network resources for on-demand applications and services. Addressing these issues presents a real challenge for WSNs and IoTs. By separating the network control plane from the data forwarding plane, Software-defined networking (SDN) has emerged as network technology that addresses similar problems of current switched-networks. Despite the differences between switched network and wireless sensor network domains, the SDN technology has a real potential to revolutionize WSNs/IoTs and address their challenging issues. However, very little has been attempted to bring the SDN paradigm to WSNs. This paper identifies weaknesses of existing research efforts that aims to bring the benefits of SDN to WSNs by mapping the control plane, the OpenFlow protocol, and the functionality between the two network domains. In particular, the paper investigates the difficulties and challenges in the development of software-defined wireless sensor networking (SDWSN). Finally, the paper proposes VSensor, SDIoT controller, SFlow components with specific and relevant functionality for an architecture of an SDWSN or SDIoT infrastructure.

“…Paths for different flows were different for QoS-aware routing mechanism depending on the comparison between flow's QoS requirements and network conditions. Take 3 Mbps realtime video streaming as an example; path (source, OFN1, OFN2, OFN3, OFN5, and sink) was determined as the route with QoS metrics (5,115,16,9), which has higher bandwidth than RIP path and lower delay than OSPF path.…”

“…As the most recognized realization of SDN, OpenFlow [8] has many inbuilt functions such as traffic statistics collection, access control, and network configuration. Some explorations on fusion of SDN and WSN have been carried out, such as Flow Sensor [9], Sensor OpenFlow [10], and Software Defined Wireless Network (SDWN) [11]. There are still many issues that need to be addressed, such as sensor network topology discovery, efficient self-organized routing mechanism, and network resource management.…”

Applications supporting various multimedia data in wireless multimedia sensor networks (WMSNs) have specific QoS requirements on bandwidth, delay, and/or packet loss. Perception of applications' QoS requirements and detection of link states are indispensable for the design of QoS-aware routing mechanism. Software defined networking (SDN) is suitable for the purpose since it provides visibility of network resources and programmable interfaces. OpenFlow is the most recognized realization of SDN. We propose a QoS-aware routing mechanism for OpenFlow-enabled WMSNs. The mechanism consists of a framework and routing algorithms on SDN controller. The framework includes two functions: detection of link states among OpenFlow-enabled nodes and determination of flow's QoS requirements. The routing algorithms are achieved in two steps. First, the SDN controller seeks the feasible paths that satisfy QoS requirements of a flow. If there is no path which satisfies the required QoS, the path will be decided by the proposed algorithms depending on flow types: delay-sensitive, bandwidth-sensitive, and best-effort traffic. We conducted experiments on a SDN testbed to evaluate our mechanism and compared the results with conventional routing protocols. The results show that proposed routing mechanism increases the throughput by 43% for video data and reduces the delay by more than 30% for audio data.

Next generation cyber-physical systems (CPS) are expected to be deployed in domains which require scalability as well as performance under dynamic conditions. This scale and dynamicity will require that CPS communication networks be programmatic (i.e., not requiring manual intervention at any stage), but still maintain iron-clad safety guarantees. Software-defined networking standards like OpenFlow provide a means for scalably building tailor-made network architectures, but there is no guarantee that these systems are safe, correct, or secure.In this work we propose a methodology and accompanying tools for specifying and modeling distributed systems such that existing formal verification techniques can be transparently used to analyze critical requirements and properties prior to system implementation. We demonstrate this methodology by iteratively modeling and verifying an OpenFlow learning switch network with respect to network correctness, network convergence, and mobility-related properties.We posit that a design strategy based on the complementary pairing of software-defined networking and formal verification would enable the CPS community to build nextgeneration systems without sacrificing the safety and reliability that these systems must deliver.
