Fog computing, which extend the cloud to the edge of the networks, is considered as a trend for future wireless sensor networks (WSNs) due to low latency and energy-saving. However, because different fog services have different quality of service (QoS) requirements and related data are forwarded by content-aware traffic control, it is a must for fog computing advanced WSNs to deploy QoS policy dynamically. Software-Defined Networking (SDN) is a future network technique that makes the underlying networks programmable dynamically. In this paper, we propose a software-defined QoD provisioning mechanism for fog computing advanced WSNs. The proposed SDN controller is able to dynamic configure QoS without any change in fogs. According to our experiment results, the latency time is greatly improved compared with cloud based WSNs. To our best knowledge, this paper is the first to realize software defined QoS provisioning for WSNs.

Abstract
Fog computing, which extend the cloud to the edge of the networks, is considered as a trend for future wireless sensor networks (WSNs) due to low latency and energy-saving. However, because different fog services have different quality of service (QoS) requirements and related data are forwarded by content-aware traffic control, it is a must for fog computing advanced WSNs to deploy QoS policy dynamically. Software-Defined Networking (SDN) is a future network technique that makes the underlying networks programmable dynamically. In this paper, we propose a software-defined QoD provisioning mechanism for fog computing advanced WSNs. The proposed SDN controller is able to dynamic configure QoS without any change in fogs. According to our experiment results, the latency time is greatly improved compared with cloud based WSNs. To our best knowledge, this paper is the first to realize software defined QoS provisioning for WSNs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
