ANALISIS PERBANDINGAN KINERJA PROTOKOL ALOHA DAN CSMACA PADA PROSES PEMBENTUKAN MOBILE AD HOC NETWORK MANET UNTUK SISTEM KOMUNIKASI TAKTIS KAPAL PERANG

ABSTRAK

Sistem komunikasi taktis adalah sistem komunikasi yang digunakan secara langsung untuk mendukung operasi militer. Komunikasi taktis harus memiliki kemampuan self-organizing self-healing dan self-forming. Permasalahan dalam sistem komunikasi taktis adalah mobilitas yang tinggi dari unit sehingga menyebabkan topologi jaringan yang berubah-ubah dan membutuhkan pembentukan jaringan yang cepat agar dapat segera berkomunikasi dan juga harus dapat menjamin setiap unit dapat berkomunikasi satu sama lain. Permasalahan ini dapat diselesaikan dengan menggunakan Mobile Ad Hoc Network MANET. Mobile Ad hoc Network MANET adalah sebuah jaringan yang terdiri dari node bergerak yang berkomunikasi melalui jaringan nirkabel tanpa dukungan infrastruktur yang tetap. Pada penelitian ini dilakukan evaluasi perbandingan kinerja protokol MAC Aloha dan CSMACA dalam proses pembentukan MANET dengan 3 tahap yaitu scanning authentication dan association sehingga parameter yang dibandingkan adalah total waktu yang dibutuhkan dalam pembentukan jaringan throughput dan skalabilitas. Formasi kapal perang yang digunakan ada tiga yaitu random burung dan star. Dari hasil simulasi didapatkan bahwa protokol CSMACA menghasilkan durasi terkecil yaitu 0.14983 detik throughput rata-rata yaitu 239.068 kbps dan nilai skalabilitas sebesar 0.6553. Sedangkan protokol MAC Aloha memiliki durasi pembentukan tercepat selama 0.61343 detik rata-rata throughput yaitu 95.55 kbps dan nilai skalabilitas sebesar 0.4537. Sehingga kinerja protokol MAC CSMACA lebih baik dari protokol MAC Aloha dalam proses pembentukan MANET.


ABSTRACT

Tactical communications system is a communication system which is used directly to support military operations. Tactical communications should have selforganizing self-healing and self-forming ability. One of tactical communication system problem is its military operation area has no fixed infrastructure so it requires a reliable network connection. Another problem is high mobility of the unit which caused the network topology changes. This problem can be solved by using a Mobile Ad Hoc Network MANET. Mobile Ad hoc Network MANET is a network that consists of mobile nodes that communicate over wireless networks without a fixed support infrastructure. This research will be carried out a comparative performance evaluation of the Aloha and CSMACA MAC protocol in the process of MANET establishment in 3 steps such as scanning authentication and association so that the parameters which compared are duration of network establishment throughput and scalability. Three battleship formations are used in this research such as random bird and star. The simulation results show that the CSMACA protocol produces the smallest duration that is 0.14983 seconds throughput is 239.068 kbps and scalability value is 0.6553. While the Aloha MAC protocol has the fastest time during the establishment is 0.61343 seconds average throughput 95.55 kbps and scalability value is 0.4537. From the results CSMACA MAC protocol has better performance than Aloha MAC protocol for MANET establishment.
