“…If the volume of a polyhedral unit is V, the volume quotient of the polyhedral unit is 3V 4πR 3 . V. Q. is always within the range [20]. Our goal is to find a space-filled polyhedron with a maximum volume quotient (i.e., close to 1) to determine a theoretically optimal partitioning solution that minimizes the number of deployed nodes and theoretically optimizes the performance of the deployed solution.…”

This paper mainly studies the deployment of wireless sensor network nodes in the warehouse environment monitoring system, discusses the deployment algorithm of wireless sensor network nodes in the warehouse environment, and finds out the node deployment scheme with better network performance through comparison. Wireless sensor network node deployment is the basis of wireless sensor network application in storage environment monitoring system. It affects the performance of the whole network and is the primary problem to be solved in network application. This paper discusses the advantages of wireless sensor network in the monitoring of storage environment, especially the deployment and simulation analysis of sensor nodes in the warehouse environment. Aiming at the influence of sensor perception model on the effectiveness of the node deployment plan, this paper proposes a node deployment collaborative perception model based on 0-1 perception model and exponential model. The sensor node deployment problem is transformed into a three-dimensional node deployment problem. Finally, the algorithm is applied to tobacco storage environment. In order to verify the effectiveness of the proposed algorithm, the scheme obtained by the proposed algorithm is compared with that obtained by the corresponding deployment algorithm in this paper. The comparison results show that the overall performance of the algorithm is better than that of the usual scheme.

“…Banyak aplikasi yang dapat dilakukan menggunakan WSN , misalnya dalam pengumpulan data pada kondisi suatu lingkungan, pengamatan keamanan dan sistem pelacak keberadaan node [7]. WSN ini telah diterapkan pada aplikasi sistem keamanan di rumah sakit [8]. Sejumlah rumah sakit dan pusat kesehatan menggunakan aplikasi teknologi WSN untuk berbagai aplikasi medis, dengan melakukan pengumpulan datadata penting pasien yang terintegrasi secara otomatis terekam ke dalam catatan perawatan pasien, korelasi dengan catatan rumah sakit, dan pengamatan jangka panjang, sehingga data-data tersebut menjadi database klinis.…”

Abstrak-Implementasi jaringan sensor nirkabel menggunakan zigbee bertujuan untuk memudahkan komunikasi antara pengguna (perawat) dengan sistem yang sedang beroprasi pada tabung inkubator bayi. Selain itu, perawat dapat selalu memantau kondisi tabung inkubator bayi walaupun berada di ruang perawat. Pada penelitian ini terdiri dari tiga bagian utama, pertama modul sensor menggunakan SHT11 sebagai pendeteksi suhu dan kelembaban tabung inkubator bayi, kedua jaringan nirkabel menggunakan ZigBee sebagai media komunikasi antara modul sensor dengan komputer, ketiga HMI (Human Machine Interface) pada komputer sebagai pengolah data yang diterima dari setiap modul sensor yang tersebar. Hasil dari penelitian ini didapatkan bahwa sistem dapat berkerja dengan semestinya dengan topologi star, sehingga komunikasi ini sangat baik bila diterapkan pada ruang lingkup yang masih dijangkau oleh end device dan coordinator. Adapun untuk ruang lingkup yang lebih luas dapat menggunakan topologi mesh dengan menambahkan router pada titik jangkauannya.

In addition, nurses can always monitor the condition of tube baby incubator at the nursing station. In this study consists of three main parts, the first sensor module using SHT11 as detection of temperature and humidity tube baby incubator, the second wireless network using ZigBee as a medium of communication between the sensor module with a computer, a third HMI (Human Machine Interface) on the computer as a data processor which received from each sensor module scattered. The results of this study found that the system can work properly with a star topology, so communication was very good when applied to the scope of which is still to reach by the end device and the coordinator. As for the broader scope can use a mesh topology to add a router at the point range. Keywords : Sensor module,wirelessnetwork, Human Machine Interface.Copyright © 2016 JNTE.

Terutama Bayi prematur umumnya perlu diletakkan pada tabung inkubator yang mempunyai sistem pengontrol suhu dan kelembaban, sehingga kestabilan suhu bayi dapat dijaga. Faktor -faktor yang perlu diperhatikan pada inkubator adalah suhu inkubator, suhu bayi, dan kelembaban dalam tabung inkubator.Pada saat ini banyak terjadi kecelakaan pada bayi di tabung inkubator, yang menyebabkan bayi mengalami kepanasan hingga bayi meninggal dunia. Faktor kejadian ini terjadi karena beberapa hal, salah satunya sistem kendali suhu dan kelembaban pada tabung inkubator bayi sudah tidak beroprasi dengan baik. Selain itu belum adanya peringatan berupa informasi jika tabung inkubator bayi bermasalah, sehingga penanganannya oleh perawat menjadi lambat.Pada penelitian ini, bertujuan u...

“…Wireless Sensor Networks (WSN) have achieved various functions such as environmental collaborative awareness of a number of microsensor nodes in the deployed observation areas, distributed processing of data information, selforganization information communication network, and so forth, by combining the microsensor technique, data processing technique, and information network communication technique. Therefore, WSNs have been widely applied to various fields such as home automation, precision agriculture, safety monitoring, smart grids, and smart cities [1][2][3][4]. Energy supply for WSN nodes has become a bottleneck that influences its further wide applications in engineering practice due to local special conditions in its application environments (military areas, depopulated areas, deep-water areas, areas without communication signals, etc.).…”

Optimization of energy consumption in Wireless Sensor Network (WSN) nodes has become a critical link that constrains the engineering application of the smart grid due to the fact that the smart grid is characterized by long-distance transmission in a special environment. The paper proposes a linear hierarchical network topological structure specific to WSN energy conservation in environmental monitoring of the long-distance electric transmission lines in the smart grid. Based on the topological structural characteristics and optimization of network layers, the paper also proposes a Topological Structure be Layered Configurations (TSLC) routing algorithm to improve the quality of WSN data transmission performance. Coprocessing of the network layer and the media access control (MAC) layer is achieved by using the cross-layer design method, accessing the status for the nodes in the network layer and obtaining the status of the network nodes of the MAC layer. It efficiently saves the energy of the whole network, improves the quality of the network service performance, and prolongs the life cycle of the network.
