Cluster-based flow control in hybrid software-defined wireless sensor networks

Software-defined networking (SDN) is a cornerstone of next-generation networks and has already led to numerous advantages for data-center networks and wide-area networks. However, SDN is not widely adopted in constrained networks, such as Wireless Sensor Networks (WSN), due to excessive control overhead, lossy medium, and in-band control...

Know when to listen: SDN-based protocols for directed IoT networks

Low-power wireless networks are an integral part of the Internet of Things, composed of resource-constrained devices harvesting ambient information.<br/>The appearance of unidirectional links is characteristic of low power wireless networking due to physical effects, device heterogeneity and manufacturing imperfections.<br/>Despite the...

No way back? An SDN protocol for directed IoT networks

The Internet of Things (IoT) has and will continue to permeate many aspects of everyday life. However, IoT de- vices often use wireless communication to transfer their data, which may experience ambient noise and multipath fading. This, together with the wide heterogeneity in types of devices, leads to the emergence of unidirectional links in...

CluFlow: Cluster-based Flow Management in Software-Defined Wireless Sensor Networks

Software-defined networking (SDN) is a cornerstone of next-generation networks and has already led to numerous advantages for data-center networks and wide-area networks, for instance in terms of reduced management complexity and more fine-grained traffic engineering. However, the design and implementation of SDN within wireless sensor networks ...

SDN and Virtualization Solutions for the Internet of Things: A Survey

The imminent arrival of the Internet of Things (IoT), which consists of a vast number of devices with heterogeneous characteristics, means that future networks need a new architecture to accommodate the expected increase in data generation. Software defined networking (SDN) and network virtualization (NV) are two technologies that promise to...
