Abstract

Perkembangan teknologi informasi telah banyak mendukung kegiatan manusia, salah satunya adalah wireless sensor network (WSN) yang diimplementasikan pada bidang perawatan kesehatan, militer, pemantauan lingkungan dan lain sebagainya. WSN merupakan salah satu jaringan nirkabel yang terdiri dari banyak node sensor yang ditempatkan di wilayah tertentu untuk fungsionalitas tertentu. Node sensor pada WSN umumnya berukuran kecil dan memiliki kemampuan komputasi, komunikasi serta penginderaan. Tugas utama node sensor adalah mengumpulkan informasi dengan melakukan sensing target seperti panas, cahaya dan suhu yang berkomunikasi melalui sinyal radio jarak dekat. Kemudian informasi ini dikirimkan ke sink dalam bentuk respon query menggunakan routing protocol tertentu. Sink bertugas untuk mengumpulkan data penginderaan dari node sensor, kemudian meneruskannya ke perangkat atau sistem lain, seperti ke database server untuk penyimpanan. Namun node sensor memiliki keterbatasan memori, sumber daya pengolahan, energi dan masa pakai. Keterbatasan dari node sensor bisa mempengaruhi kinerja jaringan, salah satunya pada sisi network lifetime. salah satu protocol yang menangani masalah network lifetime adalah Clustered Shortest geopath routing protocol (CSGP). Pada penelitian ini dikembangkan sebuah protocol dari metode CSGP dengan melakukan seleksi cluster head yang optimal yaitu berdasarkan jumlah tetangga terbanyak dan proses pergantian cluster head ketika sisa energi cluster head terpilih <= 50%. Proses seleksi ini dilakukan agar konsumsi energi lebih merata, kemudian untuk mengurangai jumlah transmisi dijaringan dilakukan agregasi data di cluster head berdasarkan prioritas data yang diterima oleh cluster head, jika data yang diterima merupakan prioritas tinggi maka akan langsung dikirim ke sink menggunakan jalur terpendek, akan tetapi jika data dengan prioritas sedang dan rendah maka akan ditampung sementara sehingga batasan tertentu. kemudian data tersebut akan di agregasi dengan cara melakukan rata-rata dari total data yang ditampung untuk tiap-tiap prioritas. Hasil penelitian menunjukkan, bahwa metode CSGP-APA dapat meningkatkan network lifetime yaitu 602 menit lebih lama, event detection meningkat 4,6% lebih tinggi, packet delivery ratio meningkat 2,4% dan latency 15 ms lebih rendah dibandingkan dengan CSGP-WA. ============================================================================================== The development of information technology had been supporting humans activity, one of them was a wireless sensor network (WSN) which implemented in the field of healthcare, military, environmental monitoring and so forth. WSN as one of the wireless networks that consisted of many sensor nodes that placed in certain areas for certain functionality. Sensor nodes on WSN were generally small and had computational, communication and sensing capabilities. The main task of sensor nodes collected information by sensing targets such as heat, light, and temperature communicating through short distance radio signals. Then the information sent to the sink in the form of a query response by using a specific routing protocol. the sink was responsible to collect sensing data from sensor nodes, then forwarding them to other devices or systems, such as to a storage server database. However, sensor nodes had limited memory, processing resources, energy and lifetime. Limitations of sensor nodes could affect network performance, such as on the network lifetime side. One protocol that handled network lifetime issues was Clustered Shortest Geopath routing protocol (CSGP). In this research, developed the CSGP method by selecting the optimal cluster head based on the highest number of neighbors and processing of replacement cluster head when the remaining cluster head energy selected by <= 50%. The selection process was done in order to the energy consumption was spread evenly, then to decrease the number of network transmission was done by data aggregation in the cluster head based on the priority data received from the cluster head. If the data was received in high priority, then it would be directly sent to the sink by using the shortest path. Another side, if the data in medium and low priority, then it would be temporarily accommodated to a certain extent. Then, the data would be aggregated by calculating the average of the total data stored for each priority. The results showed that CSGP-APA method can improve the network lifetime up to 602 minutes longer, packet delivery ratio improved by 2,4%, event detection (P1) improved by 4,6% and latency improved by 15 ms lower than to original CSGP.
