Multi-Hop Routing Protocol in SDN-Based Wireless Sensor Network
Mandeep Singh, Arun Malik · 2024
Researchers have created new protocols to meet the WSNs’ exacting needs as a result of advancements in the same. Because they depend on the design and architecture of the application, knowledge of routing protocols has been seen as a crucial issue. To monitor some locations, WSN systems compile data from a variety of sensors. Due to different restrictions placed on tiny nodes, networking and managing these sensors is a challenging operation. In WSN, software-defined network (SDN) is a new advancement to handle the network in a central controlled way. One of the fundamental approaches of SDN is that it has separated the device control planes from its data plane. By using this management of network, it becomes more convenient and provides full control over the network components. Now each controller for the network’s devices has its dedicated control plane, this reduces the burden that complex routing places on individual devices. This feature has been demonstrated to be incredibly helpful especially when it comes to WSNs with limited resources. By moving control logic out of low-power nodes, the main problems of low resource utilization and counter-productivity that WSNs face can be solved. As an emerging connectivity paradigm, deploying SDN in WSN is covered in this chapter. It is given utilizing a thorough examination of significant networking protocols and a critical assessment of their efficacy. To shed insight on upcoming developments in this subject, difficulties and open research problems are also emphasized.
