How Far Can We Go? Towards Realistic Software-Defined Wireless Networking Experiments

A versatile yet secure communication architecture is important for smart grid (SG) applications. Most developing countries are currently deploying communication infrastructure for SG implementation. Survey in literature shows automated protection and control is already done in generation, transmission and primary distribution parts of the grid so as to guarantee reliable power supply to customers. However, secondary distribution power network (SDPN) is usually not monitored. Most of the published studies dealing with communication architectures in SDPN have focused on providing solutions for home automations and smart metering applications but little attention is paid to actual power utilities’ needs and implementation challenges facing power utilities specifically when detecting and clearing faults automatically in SDPN. Most power utility companies in developing countries and Tanzania in particular face a lot of challenges when dealing with faults management in the SDPN. This is due to poorly planned and unmonitored low voltage infrastructure. In this paper, practical requirements for SDPN communication architectures are established through challenge driven education (CDE) approach and thereafter, a practical communication architecture appropriate for Tanzania Electric Supply Company Limited (TANESCO) to enable automatic and real time faults detection and clearance in SDPN is proposed. Simulation results show that the developed architecture can successfully be used to practically detect and clear faults at SDPN since it introduces an overall end to end average delay of 1.362ms which is lower than what is specified by SG application standard delay time for distribution automation (100ms).

“…In the previous reference, the authors use an emulator called MiniNet to make the tests and build their architecture. Fontes et al [17] in their work, explain in that the objective is to emulate SDN / Open-Flow scenarios that allow high fidelity in the experiments that researchers need to execute to test SDN architectures, to recreate real networking environments. The strengths of the emulator and its limitations are exposed, and they even present three cases of study in which different tests were made.…”

The campus wireless networks have many users, who have different roles and network requirements, ranging from the use of educational platforms, informative consultations, emails, among others. Currently due to the inefficient use of network resources and little wireless planning, caused by the growth of the technological infrastructure (which is often due to daily worries, rather than to a lack of preparation by those in charge of managing the network), There are two essential factors that truncate the requirement of having a stable and robust network platform. First, the degradation of the quality of services perceived by users, and second, the congestion caused by the high demand for convergent traffic (video, voice, and data). Both factors imply great challenges on the part of the administrators of the network, which in many occasions are overwhelmed by permanent incidences of instability, coverage, and congestion, as well as the difficulty of maintaining it economically. The present investigation seeks to propose a process of optimization of the infrastructure and parameters of the configuration of a wireless network, that allows maximizing the level of satisfaction of the users in Higher Education Institutions. In the first place, it is expected to determine an adequate methodology to estimate the level of satisfaction of the users (defining a mathematical criterion or algorithm based on the study variables [1], characterize the environment in which the project will be developed, making a complete study of the wireless conditions and implement optimization strategies with software-defined networks (SDN). SDN is a concept in computer networks that allows network management to be carried out efficiently and flexibly, separating the control plane from the data plane into network devices. SDN architecture consists of an infrastructure layer which is a collection of network devices connected to the SDN Controller using protocol (OpenFlow) as a protocol [2]. Also, SDN will study traffic patterns on the network as a basis for optimizing network device usage [3]. The phases of the research will be carried out following the life cycle defined by the Cisco PPDIOO methodology (Prepare, Plan, Design, Implement, Operate, Optimize) [4].

“…Reported use cases (such as those presented in [21,22] for Mininet, [23] for IMUNES (Integrated Multiprotocol Network Emulator/Simulator) or [24,25] for VNX (Virtual Networks over linuX) show the suitability of this type of tool for the study of operational networks, as long as certain accuracy loss in the results is acceptable [1,26]. Moreover, studies such as [11,12] expose how these tools can enhance the experimentation in emergent network environments.…”

Software-Driven Definition of Virtual Testbeds to Validate Emergent Network Technologies

Abstract:The lack of privileged access to emergent and operational deployments is one of the key matters during validation and testing of novel telecommunication systems and technologies. This matter jeopardizes the repeatability of experiments, which results in burdens for innovation and research in these areas. In this light, we present a method and architecture to make the software-driven definition of virtual testbeds easier. As distinguishing features, our proposal can mimic operational deployments by using high-dimensional activity patterns. These activity patterns shape the effect of a control module that triggers agents for the generation of network traffic. This solution exploits the capabilities of network emulation and virtualization systems, which nowadays can be easily deployed in commodity servers. With this, we accomplish a reproducible definition of realistic experimental conditions and the introduction of real agent implementations in a cost-effective fashion. We evaluate our solution in a case study that is comprised of the validation of a network-monitoring tool for Voice over IP (VoIP) deployments. Our experimental results support the viability of the method and illustrate how this formulation can improve the experimentation in emergent technologies.
