Interaction of the IoT Traffic Generated by a Smart City Segment with SDN Core Network

Abstract

The main purpose of this article is to test IoT management system based on SDN core network, as well as interaction IoT traffic with SDNswitsches. To conduct investigation of management system and network infrastructure behavior we carried out several IoT traffic tests, which were generated based on partnership project oneM2M specification. In this work, we considered "Smart city" model for Central district of Saint-Petersburg (Russia). During the testing of the network infrastructure were identified several parameters such as number of simultaneously supported sessions by the Mikrotik switch using different transport protocols, was proposed a recommendation for dynamically changing virtual buffers. During the testing of the IoT management system, we define reliability of IoT data management service for determined equipment in traffic conditions of the "Smart City". Also, we estimate relationship between RTT parameter using various IoT protocols and heterogeneous traffic in conjunction with "Smart city" segment in SDN network. In order to investigate the influence of the SDN network on the RTT traffic parameter of a large number of IoT and the condition of its transmission in conjunction with heterogeneous traffic in the network, a full-scale experiment was conducted on the developed model, which in turn reflected a possible distribution scheme of a certain monitoring and control system for the Central District Saint-Petersburg. The aim of the study is also to consider the possibility of implementing the IoT data management service as a central management system for monitoring urban ecological parameters in a dense buildings environment.

Forecasting Issues of Wireless Communication Networks’ Cyber Resilience for An Intelligent Transportation System: An Overview of Cyber Attacks

“…Employing software-defined networking (SDN) technology can be one such decision. This technology is based on the principle of division according to the planes of management and data, and this situation hypothetically allows realizing the above-stated exchange [81,82].…”

Future of IoT Networks: A Survey

“…The fundamental idea of SDN is to provide a feature to manage the traffic of the network in a software manner. SDN can be an essential technical feature of IoT, and research related to institute SDN into an IoT environment is currently underway [61,62]. SDN separates the control plane and data plane from the network flow to enable programming of the network.…”

The Use of UAVs, SDN, and Augmented Reality for VANET Applications

“…However, for a sufficiently long route this leads to unnecessary delays for other vehicles at the crossroads, as well as a long waiting time for ambulances. To reduce the duration of the waiting time for vehicles of regular clusters, as well as to ensure timely movement of ambulances, we propose a model based on the use of VANETs, AR applications, and the SDN architecture ( Figure 2) [12]. Note that in the proposed architecture, the UAV performs functions of an SDN controller, peripheral modules of which are located in priority cluster vehicles.…”
