Asap rokok adalah salah satu asap beracun yang berbahaya bagi kesehatan manusia dari sisi biologis maupun sisi kimiawi. Pada penelitian ini, penulis mengimplementasikansebuah sistem deteksi asap rokok berbasis The Internet of Things menggunakan sensor MQ135, Arduino board dan NodeMCU. Kemudian, penulis melakukan perbandingan Quality of Service dari dua protokol komunikasi data, yaitu Transmission Control Protocol dan User Datagram Protocol pada sistem tersebut. Parameter Quality of Service yang dibandingkan saat proses pengiriman data adalah delay dan data loss. Untuk setiap protokol, simulasi dilakukan selama 1 jam dengan pengiriman data setiap 5 detik, 10 detik, sampai 1 menit. Hasil yang diperoleh adalah data loss dengan Transmission Control Protocol lebih rendah dari pada data loss dengan User Datagram Protocol, sedangkan delay dengan User Datagram Protocol lebih rendah dari pada delay dengan Transmission Control Protocol.

Este trabalho apresenta uma aplicação desenvolvida para controlar remotamente um robô de inspeção. Para construir o projeto eletromecânico foi utilizado um kit Lego NXT Mindstorm. A aplicação foi desenvolvida em JAVA e conta com uma interface gráfica que permite operar e controlar o robô remotamente através de rotinas que rodam em um ambiente cliente / servidor. A comunicação entre estação controladora (servidor) e estação robótica é feita utilizando uma rede wi-fi, que funciona sobre o protocolo TCP (Transmission Control Protocol) e UDP (User Datagram Protocol), juntamente com o protocolo IP (Internet Protocol) configurados em uma porta de comunicação. Uma segunda camada de aplicação foi desenvolvida com um conjunto de instruções (sockets) responsáveis pela comunicação e pelos movimentos controlados do robô, os quais são transmitidos da estação servidora para estação cliente. Para modelar o sistema, os eventos, os controles e os estados do componentes robótico foram utilizados alguns diagramas da UML 2.4. O componente robótico, por sua vez, foi construído utilizando um chassi de madeira, um núcleo controlador NXT e três servo motores Lego NXT Mindstorm, além de uma estação computacional para enviar e receber os sinais Wi-Fi. Para permitir à operação e o controle a distância, fez-se necessário a instalação de uma Webcam em um dos servo motores com rotações para direita e esquerda. A finalidade da Webcam é capturar as imagens do ambiente através da estação cliente e enviá-las ao servidor em tempo real, por meio do protocolo RTP (Real-time Transfer Protocol). Um conjunto de sockets foi utilizado para enviar os comandos de operação da estação servidora ao componente robótico. Desta forma, é possível a manipulação do robô pelo controlador e o monitoramento do ambiente a ser inspecionado.

Stream Control

AbstrakStream Control Transmission Protocol (SCTP) merupakan protokol yang mirip dengan Transmission Control Protocol (TCP) dan User Datagram Protocol (UDP). SCTP merupakan protokol yang bersifat reliable dan connectionless. Protokol ini memiliki kemampuan multistreaming dan multihoming dalam melakukan transmisi data. Penelitian ini merupakan pemodelan terhadap SCTP menggunakan simulator OPNET yang dapat menjadi akselerasi bagi peneliti dalam bidang jaringan. SCTP pada simulator dibangun dengan melakukan modifikasi terhadap TCP. Pemodelan dimulai dengan membangun skenario jaringan dan menentukan bandwidth pada jalur yang akan dilewati oleh paket data.Modifikasi ukuran window dalam penelitian ini menggunakan nilai 1 MMS, 2 MMS hingga 10 MMS pada pengendali kemacetan. Tujuannya adalah untuk melihat pengaruh modifikasi ukuran window terhadap nilai packet loss, delay dan throughput. Hasil pengukuran memperlihatkan bahwa nilai throughput tertinggi terdapat pada Skenario Kedua sebagaimana diperlihatkan pada Tabel 6.4 dengan nilai throughput sebesar 433.566,0244 bit/s. Penggunaan ukuran window dalam pengendali kemacetan dimaksudkan untuk menghindari banjir data pada sisi endpoint yang dapat menyebabkan packet loss. Kata kunci—Pengendali kemacetan, throughput, delay, packet loss, ukuran window, multihoming, SCTP  Abstract Stream Control Transmission Protocol (SCTP) is a protocol that is similar to the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). SCTP is a protocol that is both reliable and connectionless. This protocol has the ability multistreaming and multihoming in the transmit data.This research is the modeling of the SCTP using OPNET simulator that can be accelerated for researchers in the field of networking. SCTP on the simulator was built to perform modifications to TCP. Modeling starts with building a network scenarios and determine the bandwidth on the path that will be passed by data packets.Modification of window size in this research using 1 MMS, 2 MMS up to 10 MMS on congestion control. The aim is to disclose the effect of modification of the window size to the value packet loss, delay and throughput. The measurement results show that the throughput rate is highest in the Second Scenario as shown in Table 6.4 with throughput value of 433.566,0244 bits/s. Using window size in congestion control is intended to prevent a flood of data on the endpoint that can lead to packet loss. Keywords—Congestion control, throughput, delay, packet loss, window size, multihoming, SCTP
