ESTIMASI TERDISTRIBUSI DENGAN COHERENT MAC DAN ORTHOGONAL MAC PADA JARINGAN SENSOR NIRKABEL
DISTRIBUTED ESTIMATION WITH COHERENT MAC DAN ORTHOGONAL MAC ON WIRELESS SENSOR NETWORK
Author : Setiawan, Syahrul Faizin
ABSTRAK
Kemajuan teknologi nirkabel memungkinkan manusia untuk
mengembangkan perangkat-perangkat komunikasi dengan tingkat
mobilitas yang lebih tinggi daripada sebelumnya. Bagaimana pengaruh
kanal yang dimodelkan dengan metode Coherent MAC dan Orthogonal
MAC untuk transmisi data antara sensor dengan fusion center dalam
berbagai kondisi.
Pada tugas akhir ini kami meneliti estimasi terdistribusi untuk
sensor dan antara sensor dengan fusion center menggunakan dua model
kanal yaitu metode Coherent MAC dan Orthogonal MAC. Kami
mengadopsi Bit Error Rate BER berdasarkan data yang diterima oleh
fusion center dari sensor sebagai kriteria kinerja atau performansi
dengan kasus ketika sumber dan observasi adalah skalar. Perhitungan
BER menggunakan metode Equal Gain Combining EGC dengan cara
mengkombinasikan sinyal informasi yang diterima yang mengalami
fading yang berbeda sehingga didapatkan satu sinya informasi hasil
kombinasi.
Hasil dari simulasi menunjukkan bahwa nilai BER untuk
Coherent MAC lebih rendah ketika range SNR antara 0 dBm sampai 18
dBm tapi pada saat range SNR diatas 18 dBm sampai 30 dBm metode
Orthogonal MAC memiliki kinerja lebih bagus dengan nilai BER lebih
kecil dan daya rata-rata yang diterima di fusion center pada saat jumlah
sensor 0 sampai 20 memiliki selish daya rata-rata sama sedangkan saat
jumlah sensor diatas antara 20 sampai 200 Coherent MAC memiliki
daya rata-rata yang lebih besar
ABSTRACT
Development of wireless technology posibility people to
develop communication devices with higher mobility rate than before.
How impact of channel to be modeled with coherent MAC and
Orthogonal MAC methods to trasmitted data between sensor to fusion
center in various of condition.
In this final project we invetigate distributed estimation for
sensor and between sensor with fusion center using two methods are
Coherent MAC and Orthogonal MAC. We adopt the Bit Error Rate
based on received data by fusion center from sensor as performance
criterion with the case when the source and observation are scalars. The
calculation of BER use Equal Gain Combining method by combining
accepted information signal that infected by different fading so that got
one the information him result of combination.
The simulations show that the result of BER for Coherent MAC
method is lower for range SNR 0 dBm until 18 dBm but for over 18 dBm
until 30 dBm Orthogonal MAC have better performance when result of
BER is lower and mean of received data by fusion center when large
number of sensor 0 until 20 have same difference but when the large
sensor over 20 until 200 Coherent MAC have mean of data received is
higher
