A Novel Wireless Sensor Networks Structure Based on the SDN

Abstract

Since the SDN (Software Defined Network) technology based on OpenFlow was born, domestic and foreign research institutions have had increasing attention to this emerging field. The OpenFlow technology which is known for standardization and compatibility network virtualization has brought a lot of innovative solutions in the field of research. As the wireless sensor network node is complex and difficult to move and the network topology is changing rapidly with time, this requires a routing protocol for it to be able to adapt to this high topology change. Because traditional WSNS protocol communication needs to consider energy consumption, load balancing and other factors, it is difficult to find one to take into account all aspects of network algorithms. In this paper, we put forward a new solution for WSNS in accordance with the OpenFlow technology research in the application of traditional network.

WSN Architecture Design Based on Software Defined Networks

“…OpenFlow technology known as standardized and compatible network virtualization technologies, has led to many innovative solutions in this field. In the literature [8], apply the OpenFlow technology to WSN and propose a new architecture model for WSN, which defines three roles as master nodes, center nodes and common nodes and adopts hybrid routing mechanism to improve the transmission efficiency to WSN [8]. However, WSN has limited energy and computing capacity.…”

“…Information fusion can provide more accurate information; meanwhile, it reduces the nodes' calculation and transmission time. Therefore, in this article, modify the model proposed in literature [8], then introduce the OpenFlow/SDN technology to WSN architecture and add letter melt layer. Establish software defined wireless sensor networks (SD-WSN) hierarchical architecture model.…”

“…FlowVisor uses network virtualization technology to establish a network virtual layer between the OpenFlow switches and controllers [8].…”

Software-Defined Networks (SDNs) and Internet of Things (IoTs): A Qualitative Prediction for 2020

“…WSN integration in SDN is seen in [41] with a three-layer architecture. It consists of master node/controller node, central node (OpenFlow enabled switch) and a normal node.…”

Extending the lifetime of wireless sensor network with partial SDN deployment

“…In SDN networks, the control plane is placed on a logically centralized controller, which maintains a global view of the network, interacts with simple data-plane and provides a programming interface for user-written network management applications. Leveraging centralized intelligence of the SDN controller, it is possible to dynamically alter the network behaviour and increase the energy efficiency [7]- [9].…”
