Network Management System for IoT Based on Dynamic Systems

The Internet of Things (IoT) has the potential to transform the public sector by combining the leading technical and business trends of mobility, automation, and data analysis to dramatically alter the way public bodies collect data and information. Embedded sensors, actuators, and other devices that capture and transmit information about network activity in real-time are used in the Internet of Things to connect networks of physical objects. The design of a network management system for an IoT network is presented in this paper, which uses the edge computing model. This design is based on the Internet management model, which uses the SNMP protocol to communicate between managed devices, and a gateway, which uses the SOAP protocol to communicate with a management application. This work allowed for the identification and analysis of the primary network management system initiatives for IoT networks, in which there are four fundamental device management requirements for any deployment of IoT devices: provisioning and authentication, configuration and control, monitoring and diagnostics, and software updates and maintenance.

SNMP for Cloud Environment Energy Efficiency

Cloud computing has seen rapid growth and environments are now providing multiple physical servers with several virtual machines running on those servers. Networks have grown larger and have become more powerful in recent years. A vital problem related to this advancement is that it has become increasingly complex to manage networks. SNMP is one standard which is applied as a solution to this management of networks problem. This work utilizes SNMP to explore the capabilities of SNMP protocol and its features for monitoring, control and automation of virtual machines and hypervisors. For this target, a stage-wise solution has been formed that obtains results of experiments from the first stage uses SNMPv3 and feed to the second stage for further processing and advancement. The target of the controlling experiments is to explore the extent of SNMP capability in the control of virtual machines running in a hypervisor, also in terms of energy efficiency. The core contribution based on real experiments is conducted to provide empirical evidence for the relation between power consumption and virtual machines.

MONITORAMENTO ON LINE DE UM SISTEMA DE MICROGERAÇÃO FOTOVOLTAICA ATRAVÉS DO PROTOCOLO SNMP

Rede de computadores são elementos fundamentais no processo de comunicação. Esses componentes exigem o acompanhamento constante de suas tarefas e são administrados por sistemas de informações que coletam os dados diariamente, para orientar os analistas de suporte na correção das falhas na infraestrutura: velocidade na transmissão de dados, desempenho de processadores, memorias de trabalho e armazenamento. E a ferramenta utilizada na gestão de recursos de rede de computadores é o protocolo SNMP. As infraestruturas de geração de energia elétrica também são elementos complexos e necessitam de acompanhamento. São utilizados sistemas de informação que disponibilizam dados para os usuários e responsáveis técnicos para avaliarem o funcionamento e corrigir as possíveis falhas: por descargas atmosféricas, falhas de equipamentos, colisão, interrupção do fornecimento de energia elétrica. Este trabalho tem como objetivo desenvolver um sistema de monitoramento on line para sistema de microgeração fotovoltaica utilizando o protocolo de rede de computadores Single Network Management Protocol (SNMP) para realizar a interface de comunicação com as variáveis de medições elétricas. O desenvolvimento do projeto compõe dois componentes: hardware e software. O software é um sistema Web. Nos componentes de hardware foram utilizados cinco microcontroladores Atmel AVR, (Arduino) todos ligados à sensores e programados para a leitura de geração e consumo de energia elétrica. Todos os experimentos foram realizados na central de microgeração distribuída fotovoltaica (MGD-PV) do Sítio Modelo da fazenda Lageado e no Laboratório de Energias Renováveis do Departamento de Engenharia Rural, nas Faculdades de Ciências Agronômicas da UNESP, campus de Botucatu. O laboratório de Energias Renováveis é o Servidor do sistema e as distâncias são muito variáveis entre todos os microcontroladores, de 32 metros a 260 metros e para realizar o processo de coleta dos dados nos diversos pontos e suprir essa distância foi necessário a construção e configuração de uma infraestrutura de comunicação baseada nas tecnologias ZigBee, para conectar os cincos microcontroladores. Os componentes de hardware e de software apresentaram rendimentos satisfatórios no processamento das informações através da interface criada pelo protocolo SNMP na comunicação e nas transmissões dos dados gerados pelos sensores, na configuração e mapeamento os objetos para construção da MIB para serem utilizados nas medições elétricas.PALAVRAS-CHAVES: Protocolo SNMP, sistemas fotovoltaicos, Arduíno, ZigBee. ON-LINE MONITORING OF A PHOTOVOLTAIC MICROGENERATION SYSTEM THROUGH THE SNMP PROTOCOLABSTRACT: Computer networks are fundamental elements in the communication process. Such components demand constant supervision of their tasks and are managed by information systems, which daily collect data to guide support analysts when correcting glitches in the infrastructure, speed of data transmission, performance of processors, working and storage memories. Protocol SNMP is the tool used for managing resources of the computer network. The infrastructures of electric energy generation are also complex elements and require monitoring. Information systems are utilized, which provide data to users and technical professionals, so they can evaluate functioning and correct possible errors, by atmospheric discharges, equipment failures, collision, interruption of the electric power supply. This work aims at developing an online monitoring system for photovoltaic microgeneration using the Single Network Management Protocol (SNMP) to perform the communication interface with the variables of electrical measurements. The project development is composed of two elements: hardware and software. The software to be use on the Web. As to hardware, we used five microcontrolers Atmel AVR, (Arduino) connected to sensors and programmed for reading the production and consumption of electric energy. All experiments were carried out at the Distributed Photovoltaic Microgeneration Central (MGD-PV) on a Model Farm and at the Renewable Energies Laboratory of the Agronomy College at UNESP, in Botucatu. The Renewable Energies Laboratory is the server of the system and the distances among all microcontrolers vary from 32 to 260 meters. Therefore, in order to collect data from several locations and neutralize such distance, we needed to build and configure a communication infrastructure based on ZigBee technologies to connect the five microcontrolers. Hardware and software components showed satisfactory performance at processing information through the interface created by the SNMP protocol regarding communication and transmission of the data generated by sensors as well as on the configuration and mapping objects for the construction of the MIB to be used in electrical measurements.KEYWORDS: SNMP protocol, photovoltaic systems, Arduíno, ZigBee.

Wireless Sensor Network Management Based on SNMP Protocol

This paper proposes a network management scheme of WSN. With embedded technology and SNMP (Simple Network Management Protocol) agent technology, an embedded SNMP agent is designed. The agent abstracts a WSN device to a virtual device as a SNMP management node. The main advantage is that the agent supports SNMP to manage the network, and diverse embedded devices can be managed identically with the conventional Internet network management. Therefore, the scheme can reduce the cost of network management and simplify the operation. Finally, by experiments, the scheme is proved to be feasible.
