“…Two groups of experiments are performed for SDN-like pub/sub topology construction, Namely, Steiner nodes under different node degrees and network sizes. In the first group of experiments, the number of network nodes is 3000; the degree of nodes changes over [1,5], [3,8] and [6,12], respectively; the pub/sub node percent varies among 20%, 30%, 50%, 70%, and 80%. In the second group of experiments, the network size changes over 500, 1000, 1500, 2000 and 3000; the degree of nodes is [1,5] or [3,8]; the pub/sub node percent is 20% or 50%.…”

“…In Internet of Things (IoT) scenarios, the publish/subscribe (pub/sub) paradigm is commonly exploited to establish the communication infrastructure for multiple clients to access tremendous real-time sensor data [1]- [5]. Software Defined Networking (SDN) [6]- [11] is used to solve the difficult problem of Quality of Service (QoS) guarantees of delivering events from publishers to subscribers in IoT. For traditional IP-based pub/sub middlewares [12], [13], event matching with defined filters takes more latency owing to a detour to broker network.…”

In traditional IP-based publish/subscribe middlewares, a detour to overlay network is demanded to match events with defined filters, which introduces more latency overhead for delivering events from publishers to subscribers. The emerging Software Defined Networking (SDN) creates boundless possibilities to improve the efficiency of event delivery because of its centralized control and customized programmability. In this paper, we propose a topic-oriented bucket-based fast multicast routing to improve the efficiency of delivering events in SDN-like publish/subscribe middlewares. First, we design an SDN-like publish/subscribe middleware hierarchical architecture with an implementation framework in SDN controller to deliver events. Topic encoding, topic prefix matching, and the subscription coverage relationships between topics are considered to reduce the number of flow entries and improve the matching abilities of SDN switches. Then, a topic-oriented multicast tree construction algorithm is proposed to build publish/subscribe overlay networks with the minimal total link delay of event transmission and minimal switches in SDN controllers to deliver events fast. A topic-oriented bucket-based multicast forwarding algorithm is designed to achieve efficient multicast forwarding in SDN switches. Finally, experiments are conducted to verify that our construction algorithm has the minimal total delay of event transmission and our bucket-based multicast forwarding algorithm is effective.

As accessibility of networked devices becomes more and more ubiquitous, groundbreaking applications of the Internet of Things (IoT) find their place in many aspects of our society. The exploitation of these devices is the main reason for the cyberattacks in IoT networks. Security design is still an open problem and a crucial step in making IoT applications successful. In dicey environments, such as e-health, smart grid, and smart cities, real-time commands must reach the end devices in the scale of milliseconds. Traditional public-key cryptosystem, albeit necessary in the context of general Internet security, falls short in establishing new session keys in the scale of milliseconds for critical messages. In this paper, a systematic perspective for securing IoT communication, specifically satisfying the real-time constraint against certain adversaries in realistic settings. First, at the network layer, we propose a secret random route computation scheme using the software-defined network (SDN) based on a capability scheme using the network actions. The computed routes are random in the eyes of the eavesdropper. Second, at the application layer, the source breaks command messages into secret shares and sends them through the network to the destination. Only the legitimate destination device can reconstruct the command. The secret sharing scheme is efficient compared to PKI and comes with information-theoretic security against adversaries. Our proof formalizes the notion of security of the proposed scheme, and our simulations validate our design.
