Abstract

Wireless sensor network loss in wireless data transmission is one of the problems that needs attention. Interference, fading, congestion, and delay are some factors that cause loss in wireless data transmission. This paper used an adaptive multi-radio model to enhance the wireless data transmission to be more robust to disturbance in a multipath fading environment. A neural network approach was used to generate the adaptive model. If we use 433 MHz as our carrier frequency with 250 kHz bandwidth and 12 spreading factors, we can get signal noise ratio (SNR) for 20 meters at about -9.8 dB. Thus, we can use the adaptive model to enhance the WSN wireless data transmission's SNR to 9 dB, automatically changing the radio configuration to 797.1 MHz frequency, with 378.1 bandwidth and 7.111 for spreading factor. Based on the result, the wireless data transmission link has been successfully enhanced using the proposed adaptive model for wireless sensor networks (WSN) in a multipath fading environment.

Abstract

Mode kompensasi yang berbeda memiliki sensitivitas berbeda terhadap perubahan koefisien kopling sistem wirelss power transfer (WPT). Nilai puncak arus kumparan transmisi berdasarkan mode kompensasi double LCC berubah relatif sedikit ketika beban berubah. Rangkaian double LCC memiliki efek penyaringan dan kehilangan siaga yang rendah saat dinamis sehingga mampu memberikan toleransi misalignment dan meningkatkan efisiensi transfer daya. Perancangan driver wirelss power transfer menggunakan topologi kompensasi induktor-kapasitor-kapasitor (LCC) yang diterapkan pada sisi transmitter dan receiver. Nilai induktor dan kapasitor dianalisa untuk mendapatkan komponen yang sesuai. Kumparan pemancar dan penerima dengan nilai induktansi dan resistansi yang beragam diuji dan dianalisa untuk mendapatkan output daya serta efisiensi yang optimal. Frekuensi 20 kHz digunakan untuk membangkitkan arus bolak balik pada rangkaian inverter. Pada jarak kumparan terdekat 0 cm dengan suplai tegangan 12 V DC mampu mentransmisikan tegangan sebesar 7,55 V DC dan arus sebesar 0,67 mA. Daya yang dihasilkan sebesar 5,06 watt. Efisiensi daya yang dihasilkan dengan menggunakan kompensasi LCC sebesar 44,15 %. Kumparan Tx dan Rx memiliki jumlah lilitan yang sama yaitu 100 dengan bentuk spiral persegi.
