Abstrak
Abstrak Jaringan Sensor Nirkabel (JSN) bekerja dengan keterbatasan energi dan bandwidth, sehingga perlu dilakukan pengukuran kinerja untuk mengetahui tingkat kehandalan yang optimal. Fokus penelitian ini adalah mengukur dan menganalisa kinerja dari JSN berbasis protokol ZigBee. Parameter Quality of Service (QoS) yang diukur adalah rata-rata delay, rata-rata throughput dan persentase packet loss. Pengujian dilakukan dengan memvariasikan nilai ukuran paket data, interval waktu pengiriman, jarak transmisi, transmisi Line of Sight (LOS) dan transmisi Non Line of Sight (NLOS). Perangkat nirkabel yang digunakan dalam penelitian ini adalah XBee S2 (ZigBee) yang merupakan perangkat komunikasi nirkabel dari Digi International. Sotfware X-CTU digunakan untuk mengkonfigurasikan modul ZigBee. Software Docklight digunakan untuk simulasi JSN secara real time melalui pengaturan variabel paket data, interval waktu penyensoran, waktu saat pengiriman dan penerimaan, serta log data hasil pengukuran. Pengujian yang telah dilakukan memperlihatkan bahwa semakin besar ukuran paket data yang ditransmisikan maka rata-rata delay transmisi dan throughput semakin besar. Variasi interval waktu pengiriman cenderung tidak mempengaruhi nilai rata-rata delay dan throughput untuk setiap jenis pengiriman paket data. Nilai persentase packet loss pada transmisi LOS adalah 0% untuk setiap ukuran paket data dengan jarak transmisi maksimum 120 meter, sedangkan pada transmisi NLOS persentase packet loss terbesar pada pengiriman paket data 80 bytes pada posisi nodal sensor ke-4, yaitu mencapai 95,31%. Hasil pengujian jaringan mesh (2 hop) memperlihatkan bahwa nilai rata-rata delay cenderung lebih besar dan rata-rata throughput cenderung lebih kecil dibandingkan dengan jaringan point to point (1 hop). Kata kunci : Docklight, Jaringan Sensor Nirkabel, Quality of Service, XBee,ZigBee Abstract Wireless Sensor Networks (WSN) working with limited energy and bandwidth, it needs a performance measurement to determined the level optimal reliability. The focus of this research is to measure and analyze the performance of Wireless Sensor Networks (WSN) based on ZigBee protocol. The Quality of Service (QoS) parameters are measured average delay, average throughput and packet loss percentage. This experiment is done by varying the values of packet length, transmitting time interval, distance, Line of Sight (LOS) transmission and Non Line of Sight (NLOS) transmission. The wireless hardware for experiment used XBee S2 (ZigBee) modules from Digi International. X-CTU sotfware is to configure the XBee module. Docklight sotfware is to simulate WSN in real time by setting the variable such as data packet, transmitting time interval, transmitting and receiving time, also log data result. The result shows that average delay and throughput increases as value of packet length increases. Difference transmission time interval isn’t impact to average delay and throughput for each packet length transmission. Packet loss persentage of LOS transmission is 0% for each data packet transmission to maximum transmission distance of 120 meters, although at NLOS transmission largest packet loss persentage value on the 80 bytes data packet transmission on position 4th sensor node, reaching 95,31%. The result of mesh (2 hop) network experiment shows that’s value of average delay more then point to point (1 hop) network and average throughput less then point to point (1 hop) network. Key words : Docklight, Wireless Sensor Networks, Quality of Service, XBee, ZigBee
