“…Rx Sensitivity / Noise merupakan sensitivitas dari antenna penerima (Rx) dalam hal menangkap sinyal WiFi dari antenna pemancar (Tx), semakin besar gangguan pada jaringan wireless baik itu karena interferensi, difraksi, refleksi, dan absorbsi akan mambuat nilai Rx Sensitivity semakin besar. Rx Sensitivity yang semakin besar akan berpengaruh padakualitas sinyal yang didapat [12].…”

Salah satu permasalahan jaringan internet di pedesaan adalah sulitnya menyambungkan internet yang berbasis kabel dikarenakan jarak terlalu jauh, jaringan internet berbasis nirkabel/wireless dapat menjadi solusi alternatif dari permasalahan tersebut, oleh karena itu dilakukan penelitian analisis perhitungan Power Link Budget pada perencanaan jaringan internet wireless outdoor Desa Kutanagara Garut. Pengujian dilakukan metode perhitungan Power Link Budget dan simulasi menggunakan aplikasi ISP Design Center Ubiquiti dengan perangkat pemancar LiteAP GPS dan perangkat penerima NanoBeam 5AC. Perencanaan jaringan dibuat menggunakan sistem Point to Point (PTP) pada pita frekuensi 5725 MHz tepatnya di 5725 MHz Sub Band NII-3. Parameter yang diuji adalah SOM (EIRP, margin signal), free space loss (FSL), fresnel zone clearance (FZC), daerah cakupan, kekuatan sinyal yang didapat dan kapasitas kecepatan internet. Hasil dari perhitungan dan konfigurasi menunjukan nilai EIRP pengirim 36 dBm, EIRP penerima 36 dbm, bandwidth maksimum 20 MHz, Fresnel zone clearance 3,4 m dan kekuatan sinyal yang diterima -49 dBm. Hasil tersebut sudah memenuhi standar yang ditetapkan oleh KOMINFO dan dapat dibuat rancangan jaringannya. Hasil dari simulasi jaringan menunjukan rancangan jaringan internet sudah mencakup seluruh daerah Desa Kutanagara Garut dengan perkiraan sinyal yang didapat adalah -49 dBm, dengan margin sinyal sebesar 46,2 dB yang sudah memenuhi standar dari TIPHON dengan klasifikasi jaringan termasuk dalam kategori outstanding (sangat bagus) dan memiliki kapasitas maksimum internet 147 Mbps terdiri dari 74 Mbps kecepatan download dan 74 Mbps kecepatan upload

To further prolong the lifetime of wireless sensor network (WSN), researchers from various countries have proposed many clustering routing protocols. However, the total network energy consumption of most protocols is not well minimized and balanced. To alleviate this problem, this paper proposes an energy-efficient clustering routing protocol in WSNs. To begin with, this paper introduces a new network structure model and combines the original energy consumption model to construct a new method to determine the optimal number of clusters for the total energy consumption minimization. Based on the balanced energy consumption, then we optimize the AGglomerative NESting (AGNES) algorithm, including: (1) introduction of distance variance, (2) the dual-cluster heads (D-CHs) division of the energy balance strategy, and (3) the node dormancy mechanism. In addition, the CHs priority function is constructed based on the residual energy and position of the node. Finally, we simulated this protocol in homogeneous networks (the initial energy = 0.4 J, 0.6 J and 0.8 J) and heterogeneous networks (the initial energy = 0.4–0.8 J). Simulation results show that our proposed protocol can reduce the network energy consumption decay rate, prolong the network lifetime, and improve the network throughput in the above two networks.
