There is a decrease in QoS due to collisions when connecting to an Access Point (AP). The collision is caused not only by the density of nodes reaching out to the Access Point simultaneously but can also be due to hidden nodes on a Network. This Hidden Node issue is not spared on the latest standard network, IEEE 802.11ah. This research assesses the impact of hidden nodes within an IEEE 802.11ah network protocol using NS-3 (Network Simulator - 3). The parameters of measurement are the delay, Packet Delivery Ratio (PDR), energy consumption and throughput on the AP side. The simulation is done using several network scenarios: i) with and without hidden nodes, ii) where the number of nodes and hidden nodes increase, and iii) set with the Restricted Access Window (RAW) features. We conclude that performance of the network deteriorate with the presence of hidden nodes with RAW features on IEEE 802.11ah network standard. [ABSTRACT FROM AUTHOR]

Limited area coverage, power consumption and the error rate is quite high, as well as bandwidth limitations, capacity of link, causes some of the performance of a system is not functioning optimally. IEEE 802.11ah designed to work at sub - 1 GHz frequency band, coverage area up to 1 Km, low energy consumption, and can handle a large of device connected to the access point. This research has compared AODV and DSDV routing protocol on IEEE 802.11ah standard using NS3. The parameter comparison is throughput, delay, packet delivery ratio, and energy consumption. Based on the result, overall performance of the network using AODV routing protocol is much better than the routing protocol DSDV applied to the IEEE standard 802.11ah. In the changing scenario the number of RAW accompanied by changes the nodes and the duration of RAW, the routing protocol AODV gain average value packet delivery ratio is about 8.49%.

There is a current need for simple and efficient information technology for ad hoc networks. The ad hoc network is a wireless LAN technology that doesn't require any infrastructure on its network. But wireless technology usually has limited resource. The IEEE 802.11ah standard was created to solve that problem. The IEEE 802.11ah is designed to work at sub-1 GHz frequency band, the transmission range up to 1 Km, has over 100 Kbps for data rate, small power consumption, and can serve up to 8191 Station. This research has compared Destination Sequenced Distance Vector (DSDV) and Optimized Link State Routing (OLSR) routing protocols on IEEE 802.11ah standard using Network Simulator 3. The simulations have performed with two scenarios, i.e. the increment number of node and the increment of distance between station (STA) and access point (AP). Whereas the parameters for comparison are energy consumption, throughput, packet delivery ratio, and average delay. Based on the results and analysis, the OLSR routing protocol has better performances than DSDV for all parameters comparison. The ratio of energy consumption between OLSR and DSDV is 1,03% for the increment number of node scenario and 2,43% for the increment of distance between station (STA) and access point (AP) scenario.
