Pada sistem kelistrikan, monitoring perlu dilakukan untuk mengatasi terjadinya gangguan dan pemanfaatan energi listrik yang kurang efektif. Monitoring listrik saat ini masih dilakukan menggunakan alat ukur sederhana dan pencatatan nilai terukur secara manual. Kekurangan tersebut dapat diatasi dengan merancang sebuah sistem monitoring listrik tiga fasa jarak jauh berbasis wireless sensor network (WSN) menggunakan komunikasi LoRa. Sistem yang dibangun terdiri dari node transmitter sebagai alat ukur tegangan, arus listrik, frekuensi, faktor daya, dan daya aktif dengan memanfaatkan modul PZEM- 004T. Node receiver berfungsi sebagai gateway yang dapat menerima data dari node transmitter secara wireless. Data yang diterima receiver kemudian disimpan ke database melalui server menggunakan jaringan internet. Ketika node receiver tidak terkoneksi dengan jaringan WiFi, data akan secara otomatis disimpan pada micro SD card. Web monitoring dirancang untuk memudahkan pengguna mengakses data monitoring listrik. Web monitoring akan menampilkan data tegangan, arus listrik, frekuensi, dan faktor daya dalam sistem satu fasa serta daya aktif dalam bentuk tiga fasa ke dalam bentuk tabel dan grafik.

Flowing Fluid

Researchers have been focused on the influences of flowing fluid on the corrosion of bare metals, but there is little emphasis on the degradation of metal-protective coating. Evaluating the metal-protective coating usually uses the Electrochemical Impedance Spectroscopy (EIS) method. EIS is a technique used for evaluating coating permeability or barrier performance based on the electrical impedance of coating. This paper presents a new impedance-based wireless sensor network for metal-protective coating evaluation. This wireless sensor network consists of two parts: impedance-based wireless sensor nodes and a wireless data base that are equipped with a network analyzer (AD5933) and a RF transceiver (CC1111/CC1110). In the experiment, there are three coating panels immersed in flowing deionized water (DI water) and one coating panel immersed in stationary DI water. Experimental results demonstrate that the proposed wireless sensor network is capable to evaluate the coating degrading.

Abstract In this paper a prototype framework for simulation of wireless sensor network and its protocols are presented. The framework simulates operation of a sensor network with data transmission, which enables simultaneous development of the sensor network software, its hardware and the protocols for wireless data transmission. An advantage of using the framework is converging simulation with the real software. Instead of creating a model of the sensor network node, the same software is used in real sensor network nodes and in the simulation framework. Operation of the framework is illustrated with examples of simulations of selected transactions in the sensor network.

Significant Concentration

A Wireless Sensor Network (WSNs) is popular developing the field in industrial and other major markets. Wireless data security is the central theme in the WSNs application where security of transmitted data is more concerned. Due to the significant concentration of energy efficiency and performance analysis in WSN, providing secured communication is a challenging issue. To overcome this interdependent problem Game theory can be used. Game theory is applied here to select different routes to transfer the data from source to destination. The performance of the WSNs can be increased by providing security for transmitted data. The graph for throughput, end to end delay, delivery, and packet loss ratio are generated using NS2 simulation tool.

Wireless Sensor Network (WSN) is an emerging area in past few decades. Through the integration of low cost sensor nodes with Internet of Things (IoT), lots of applications are common now these days. Each application senses and transmits the fused data to the sink. This wireless data transmission is called routing and is the main governing factor for the span of the sensor network. This paper analyzes and presents different variety of routing techniques based on connectivity structure of the sensors. The type of application for which sensor nodes are used governs selection of a routing technique.
