Fuzzy Logic Method as Determining of Internet Network VSAT performance in Black Spot Region at District of Enrekang

Abstract

Internet networks using VSAT have some disadvantages caused by the relative distance of the satellite and the earth which is a significant propagation delay. To determine the optimal quality of VSAT internet network, a study of VSAT internet network performance was performed using Fuzzy Logic method, based on the parameters of bandwidth, delay, packet loss, and throughput conducted for 2 days in the morning, afternoon and night in 2 villages in Enrekang Regency, namely Singki Village and Tindalun Village. Retrieval of data parameters at these locations using a wireshark application software which is then inputted into fuzzy logic so as to produce three categories of performance, good or sufficient, and bad network quality. It is said that performance is good if the results on fuzzy logic are 0, sufficient performance compilation of results from fuzzy logic is 0.5 and performance is poor if the results of fuzzy logic are valued 1. The VSAT internet network requests optimal compilation parameters of network quality such as 6 mbps bandwidth, delays below 1,000 ms, packet loss less than 50% and throughput above 50 kbps which has been designed in fuzzy logic. From the results of the study, obtained a value for the village of Tindalun 0.5 which means enough. Whereas, for performance in Singki Village, 2 different values were obtained, while compilation using Wifi was valued at 0.5, which was sufficient, and compilation using WireLAN was 0 which meant good.
