IEEE 802.11ah is a new task group on the IEEE 802.11 standard designed to work on the 900 MHz. It is with a range of communication coverage up to 1kilometer, lower energy consumption, and up to 8191 stations. There are two types of STAs in 802.11ah: sensor type to support sensor service and non-sensor type for offload service. In this research, it only focuses on non-sensor STA. For non-sensor STA, maximizing throughput is more important than power consumption. This research aims to see the performance of IEEE 802.1 1ah with Enhanced Distributed Channel Access (EDCA). To achieve that purpose, a mechanism is needed to provide guarantees various services required by theSTA. EDCA is an access mechanism used to set the Quality of Service (QoS) for the IEEE 802.11 standard through modifications in MAC layer. In this research,it focuses on one of the EDCA parameters, Arbitration Inter-Frame Space (AIFS). In addition, this research also focuses on the 802.11ah feature is Restricted Access Window (RAW) by changing the number of the RAW groups. From the results of the research, it is found that the improvement scheme with Arbitration Inter-Frame Space Number (AIFSN) value AC BK = 2, AC BE = 1, AC VI = 1, AC VO = 1 has better performance compared to the default scheme with AIFSN value AC BK = 7, AC BE = 3, AC VI = 2, AC VO = 2) with an average throughput of 1.504598 Mbps, average overall delay of 0.066242 second and average PDR of 62%. In addition, changes in the number of RAW groups and RAW slots affect network performance. This feature can improve the value of throughput, average delay, and Packet Delivery Ratio. The goals of this research is to know the effect of AIFSN value changes on AIFSN parameters, variation of RAW group and RAW slot number to throughput,average delay and packet delivery ratio.

Abstrak -Meningkaatnya kebutuhan dan permintaan layanan yang beragam oleh user untuk dapat bertukar dan mendapatkan informasi secara real time, reliable, dan fleksibel menjadi salah satu permasalahan yang dihadapi oleh teknologi komunikasi yang ada saat ini. WLAN pada standar IEEE 802.11 merupakan salah satu teknologi wireless yang dapat menjadi solusi dari permasalahan tersebut. Memiliki cakupan area komunikasi yang tidak terlalu luas, yaitu antara 20-70 meter saja, hanya mampu melayani hingga 2007 stasiun, dan memiliki konsumsi energi yang cukup besar, menyebabkan beberapa sistem yang terdapat pada WLAN pada standar IEEE 802.11 kurang bekerja secara maksimal. Dengan beberapa kekurangan tersebut, maka WLAN pada standar IEEE 802.11 mengenalkan task group baru yang disebut IEEE 802.11ah. IEEE 802.11ah adalah standar WLAN baru yang bekerja pada spektrum frekuensi 900 MHz, cakupan area komunikasi yang mencapai 1 kilometer, mampu melayani 8192 stasiun dengan hierarki AID yang baru, memiliki konsumsi energi yang lebih rendah dan mampu meningkatkan nilai throughput dengan mekanisme RAW. Penelitian ini melakukan perubahan jumlah RAW slot pada IEEE 802.11ah untuk melihat bagaimana pengaruhnya terhadap performansi jaringan. Pada penelitian ini didapatkan bahwa perubahan jumlah RAW slot berpengaruh terhadap performansi jaringan, dalam hal ini adalah throughput, average delay, packet delivery ratio, dan energy consumption.Kata kunci -IEEE 802.11ah, RAW, RAW Slot Abstract -The increasing needs and demands of diverse services by the users to be able to exchange and obtain information in real time, reliable, and flexible to be one of the problems faced by existing communication technology. WLAN on the IEEE 802.11 standard is one of the wireless technologies that can be the solution to the problem. It has a relatively small area of communication that is between 20-70 meters only, only able to serve up to 2007 stations, and has considerable energy consumption, causing some systems contained in the WLAN in IEEE 802.11 standard less work maximally. With these shortcomings, the WLAN on the IEEE 802.11 standard introduces a new task group called IEEE 802.11ah. IEEE 802.11ah is a new WLAN standard working on the 900 MHz frequency spectrum, a 1 kilometer communications coverage area, capable of serving 8192 stations with new AID hierarchies, has lower energy consumption, and can increase throughput value by the RAW mechanism. This study will make changes to the number of RAW slots in the IEEE 802.11ah to see how they affect the network performance. In this research, it is found that the change of RAW slot number influence to network performance, in this case, is throughput, average delay, packet delivery ratio, and energy consumption.Keywords -IEEE 802.11ah, RAW, RAW Slot I.
