Salah satu upaya perlindungan dari potensi bahaya radiasi di lingkungan sebagai dampak dari adanya lepasan radiasi disekitar fasilitas nuklir adalah dengan pemantauan dosis radiasi di lingkungan secara waktu nyata dan terus-menerus. Penelitian ini mengkaji sistem pemantaun radiasi di lingkungan yang telah diterapkan saat ini, kemudian mengembangkan sistem tersebut agar lebih berdayaguna dalam rangka kesiapsiagaan nuklir. Pengembangan sistem dilakukan melalui penambahan jaringan sensor nirkabel dan fitur peringatan dini.Jaringan sensor nirkabel JSN yang diaplikasikan kedalam sistem, meliputi JSN berbasis radio frekuensi RF dan general packet radio service GPRS. Faktor koreksi hasil pengukuran JSN GPRS tipe Pancake terhadap peralatan komersial JSN RF untuk pengukuran paparan radiasi lingkungan adalah 0.657, sedangkan faktor koreksi JSN GPRS tipe NaI Tl adalah 0,502. Data yang dikirim oleh perangkat deteksi gamma dikumpulkan di server yang dikelola oleh Pusat Pendayagunaan Informatika dan Kawasan Strategis Nuklir PPIKSN-BATAN. Data yang diterima server disimpan di database xmonitoring, dapat dilihat secara langsung nilai paparan radiasi di lingkungan melalui phpmyadmin. Disain website dapat dikunjungi pada alamat http: 223.25.97.90/radmon-farid/index.php. Sistem peringatan dini akan dikirimkan ke operator penanggungjawab sistem radmon, apabila parameter pembatas paparan radiasi lingkungan sebesar 0,3 ?Sv/jam terlampaui. SMS peringatan dini akan dikirimkan kepada operator sistem radmon setelah 15 - 60 detik data pengukuran paparan radiasi lingkungan diterima oleh server.

Integrasi lightweight blockchain dengan Wireless Sensor Network (WSN) telah menyelesaikan beberapa masalah seperti authentikasi, authorisasi, keamanan dan integritas data. Namun, belum ada studi yang berfokus memperhatikan network lifetime pada blockchain yang diterapkan pada WSN. Penelitian ini berupaya memodifikasi algoritma Proof-of-Authority (PoA) agar lebih adil dalam pembagian penggunaan energi yang ditujukan untuk meningkatkan network lifetime sekaligus produksi blok. Jenis jaringan yang digunakan adalah WSN terklaster karena memiliki penggunaan energi yang lebih baik. WSN terklaster terdiri dari Base Station, Cluster Head dan Sensor Node yang memiliki tugasnya masing-masing. Dalam hal network lifetime, studi ini mengembangkan Proof-of-Authority menjadi Energy-aware Proof-of-Authority (EA-PoA) yang memodifikasi pertukaran pesan dan pemilihan Leader. EA-PoA memodifikasi pemilihan pengusul blok (Leader) yang awalnya menggunakan round-robin menjadi pemilihan berdasarkan pembobotan battery level pada setiap perangkat. Dengan demikian, node yang memiliki baterai lebih sedikit tidak akan terbebani oleh proses mining. Sedangkan dalam hal produksi blok, penelitian ini telah mengembangkan model jaringan blockchain hirarki yang terdiri dari local dan master blockchain yang disebut Multi-level blockchain model (MLBM). Local blockchain adalah jaringan blockchain untuk setiap klaster dengan anggota Node Sensor. Blok yang diusulkan dan disimpan dalam jaringan local blockchain merupakan data sensor. Sedangkan master blockchain beranggotakan Cluster Head dari setiap klaster, blok yang diusulkan dan disimpan adalah kumpulan header dari beberapa blok dalam local blockchain. Hal ini dilakukan untuk meningkatkan integritas data sekaligus mengingkatkan produksi blok dalam jaringan. Hasil simulasi menunjukkan bahwa mekanisme pemilihan Leader dari EA-PoA dapat meningkatkan network lifetime hingga 10% dibandingkan PoA tradisional. Selanjutnya, Multi-level blockchain model dapat meningkatkan produksi blok setiap penambahan klaster dalam jaringan. ......The integration of lightweight blockchain with Wireless Sensor Network (WSN) has addressed several issues such as authentication, authorization, security, and data integrity. However, no study has specifically focused on the network lifetime of blockchain implemented in WSN. This research aims to modify the Proof-of-Authority (PoA) algorithm to more equitably distribute energy usage to enhance both network lifetime and block production. The type of network employed is clustered WSN, known for its better energy usage. Clustered WSN consists of a Base Station, Cluster Head, and Sensor Nodes, each with distinct responsibilities. In terms of network lifetime, this study develops Proof-of-Authority into Energy-aware Proof-of-Authority (EA-PoA), which modifies message exchange and Leader selection. EA-PoA alters the block proposer (Leader) selection from a round-robin method to a battery-level weighting method for each device. Thus, nodes with lower battery levels are not burdened by the mining process. Regarding block production, this research has developed a hierarchical blockchain network model called the Multi-level Blockchain Model (MLBM), which consists of local and master blockchains. The local blockchain serves as the blockchain network for each cluster with Sensor Node members, where proposed and stored blocks contain sensor data. The master blockchain consists of Cluster Heads from each cluster, where proposed and stored blocks are collections of headers from several blocks in the local blockchain. This approach is designed to enhance data integrity and increase block production within the network. Simulation results indicate that the Leader selection mechanism of EA-PoA can extend network lifetime by up to 10% compared to traditional PoA. Furthermore, the Multi-level Blockchain Model can increase block production with each additional cluster in the network.

This book documents some of the most recent advances on the physical layer of the Internet of Things (IoT), including sensors, circuits, and systems. The application area selected for illustrating these advances is that of autonomous, wearable systems for real-time medical diagnosis. The book is unique in that it adopts a holistic view of such systems and includes not only the sensor and processing subsystems, but also the power, communication, and security subsystems. Particular attention is paid to the integration of these IoT subsystems as well as the prototyping platforms needed for achieving such integration. Other unique features include the discussion of energy-harvesting subsystems to achieve full energy autonomy and the consideration of hardware security as a requirement for the integrity of the IoT physical layer. One unifying thread of the various designs considered in this book is that they have all been fabricated and tested in an advanced, low-power CMOS process, namely GLOBALFOUNDRIES 65nm CMOS LPe.
