Widada, Abdul Aziz Hadyansyah (2019) Optimasi Penempatan Relay Node Pada Wireless Sensor Networks Menggunakan Algoritme Particle Swarm Optimization (PSO). Sarjana thesis, Universitas Brawijaya.
Abstract
Konsep precision agriculture diprediksi akan menjadi masa depan sektor pertanian. Penerapan teknologi informasi pada automasi produksi hingga keamanan lahan mengharuskan areal pertanian dipenuhi perangkat sensing. Pada kenyataannya, banyak sensor yang telah disebar pada lahan tidak dapat mengirimkan data secara optimal. Keterbatasan daya dari perangkat wireless sensing menyebabkan konektivitas jaringan menjadi kurang dan mempengaruhi hasil akhir pemantauan lahan. Topik relay node placement dalam ranah wireless sensor networks menghadirkan solusi keterbatasan daya tersebut dengan membagi peran aktuator data lapangan dan sebagai hop yang meneruskan data menuju internet gateway. Namun penerapan arsitektur komunikasi two-tier menggunakan relay membutuhkan biaya yang cukup tinggi, sehingga penempatannya perlu dioptimasi. Penelitian ini dilakukan bertujuan untuk mengoptimasi penempatan relay pada lahan pertanian, dengan mengusulkan strategi optimasi yang disesuaikan dengan kondisi di lapangan. Algoritme PSO (Particle Swarm Optimization) digunakan sebagai metode heuristik optimasi penempatan relay. Hasil optimasi penempatan relay menunjukkan bahwa kumpulan relay yang dioptimasi jumlah dan posisinya, dapat menghasilkan nilai konektivitas maksimal dibanding penempatannya secara deterministik. Adapun kompleksitas metode akan meningkat 19-35 persen seiring bertambahnya jumlah relay yang dipertimbangkan.
English Abstract
Precision agriculture is predicted to become the future of the agricultural industry. The application of information technology to enhanced production automation or land security requires that agricultural areas be filled with sensing devices. In fact, many sensors that have been deployed on land cannot send data optimally. The battery lifetime of wireless sensing devices causes network connectivity to be less and affects the final results of land monitoring. Relay node placement in wireless sensor networks field presents a power-limiting solution by dividing the role of data actuators and as hops that forward data towards internet gateway. However, the application of two-tier communication architecture using relay requires a high cost, so that the relay placement needs to be optimized. The research was conducted aimed at optimizing the placement of relays on agricultural land, by proposing optimization strategies that are adapted to conditions in the field. PSO (Particle Swarm Optimization) algorithm is used as a relay placement optimization heuristic method. The results of relay placement optimization show that a collection of relays that are optimized in number and position can produce maximum connectivity value compared to its placement deterministically. The complexity of the method will increase 19-35 percent as the number of relays is considered.
