Abstract

Transmission control protocol (TCP) is a protocol at the transport layer that provides a reliable data transfer mechanism, so that the data stream reads TCP receiver is not corrupted, without duplication, and sequentially. To provide reliable data transfer, TCP provides error checking and flow control services. When the TCP sender sends data faster than the TCP receiver can handle, congestion will occur. TCP implements a congestion control mechanism for network traffic control so no congestion occurs. This study compares the performance of four variants of TCP congestion control, namely TCP Cubic, Reno, Vegas and Westwood +. The test is to analyze cwnd, ssthresh and throughput of four types of TCP Congestion Control algorithm. The author uses two devices as a sender and receiver. Both are connected with an ethernet cable that has a connection with 100Mbit/s bandwidth. TCP data is collected on the sender side using TCP Probe and the result is shown as a graph with Gnuplot. The results of this study indicate that TCP Westwood + is the best among the three other TCPs in all Service Center agreement (SLA) service provider environments with Bandwidth Estimation mechanisms they use.

Abstract

Wireless Sensor Network is a technology used in obtaining data from physical conditions or environmental conditions with the help of sensors. Wireless Sensor Network consists of several nodes that will transmit data on the Gateway node. Wireless Sensor Network communication requires the same Channel to connect between nodes. Problems with the Wireless Sensor Network if the area is monitored widely and the nodehas multi- channels will require a lot of Gateway nodes according to the number of channels. Wireless Sensor Network communication like this is less concise and requires extra funds. Based on the problems mentioned in this research applied Wireless Sensor Network communication with multi-channel. Multi-channel will improve the performance of data transmission so that on the Gateway nodethere are several channels for communication with the node. The method in this study is another SPI (Serial Periperal Interface) on the node, I2C on the Gateway node. The results of Wireless Sensor Network communication with Multi-Channel method can improve the delivery and data reception performance. The node address specification has an important role in multi-channel communication to perform channel switches in receiving data on the server. Data obtained by the server successfully received at the same time, but it takes approximately 2 - 4 seconds of synchronization at the beginning communication.

Abstract

The application of Wi-Fi networks is getting easier, even now it can be found on some public transport. So it is not impossible if applied to passenger trains. However, the implementation of passenger trains may be confronted by several issues such as coverage area (railway) which is made of iron and steel. As in previous research, observing railway propagation losses is important because it affects signal strength (We, Ito, Yokoyama, Tseng, Sagawa, Ogasawara) and based on research on wifi network optimization in the recovery room there are several aspects that need Be considered as aspect of propagation, and coverage area aspect. (Widyaningsih, 2013) Therefore it is necessary to observe and calculate the appropriate, so as to produce an effective design. Up to the furthest distance of 21 meters the Link Budget calculator the RSL value is -43 dBm and SOM is 51 dB, with the value known that the radiated signal can spread well. And for the calculation of the number of Access Point based on the reach of the Access Point and the capacity of the client obtained at least 3 Access Point that can meet the needs in passenger trains. And from the application of the simulation with the placement of 3 Access Point, with a maximum transmit power of 18 dBm and also the application of different channels, has resulted in an average value of RSSI -35 dBm to -55 dBm, which with the value of signal characteristics interpreted in very good (Excellent).

Abstract

Message Queue Telemetry Transport - Sensor Network (MQTT-SN) is a communication protocol derived from the Message Queuing Telemetry Transport (MQTT) protocol that applied to the sensor network. To apply MQTT-SN requires Quality of Service (QoS). QoS is a method of measuring the quality of network and an attempt to define the characteristics and properties of a service so that messages are received. The Application of QoS in MQTT-SN is very important to ensure the receipt of data. This research implies QoS mechanism on Arduino Nano with NRF24L01 wireless communication using MQTT-SN message format. In this research is tested with different QoS level to get different result in each level of QoS. MQTT-SN with QoS level 0 allows packets not to reach the gateway because publishers continue to publish without any reciprocity from the gateway that make publishers don't know wether the message is delivered to the destination or not, and average accepted message 70%. While MQTT-SN with QOS level 1 the gateway can not distinguish publish data at the first time and next so duplicated messages can be happen until 30%. MQTT-SN with QoS level 2, the message is received exactly once due to temporary data storage on the gateway that make protocol will ignore data that is not needed and average accepted message 100%.
