Abstract

Internet of Things (IoT) is currently developing technology. Wireless Sensor Network (WSN) is one of technology that use IoT scenario. In the implementation of WSN concept there is constraint on the limited resources that they have. Limited resources cause WSN data processing need to be handled in other systems such as data center. Therefore, to connect communication between sensor node and the data center, gateway device is needed. In this research gateway device will be implemented to bridging communication between sensor nodes and data centers. Communication between gateway and sensor nodes can use the nRF24L01 module which has advantages in low power consumption and supports RF24Mesh protocol which can be applied to wireless sensors. Communication between the gateway and data center can use the MQTT protocol, where this protocol is suitable for devices with limited resources and low bandwidth. The successful rate performance of the gateway built with the nRF24L01 wireless communication module show that the gateway performance at 20 meters distance with 50 Byte packet size and 1 second delay packet delivery has the best performance. Delivery at 30 meters distance and 150 Byte packet size cannot be done because exceeding the distance range and the packet size.

Abstract

The Internet of Things is the interconnection of various devices over the internet, allowing these devices to communicate with one another. The diversity of requirements and format of data from devices in IoT might cause problems in the aspect of interoperability. The integration of IoT with Web of Things (WoT) can serve as a solution so that users can access devices in IoT through the same source. One technology that is easier to implement using IoT and WoT is Smart Home (home automation). In Smart Home there are devices like sensors and microcontrollers with limited resources, therefore the MQTT protocol is used as a support for communication. WebSocket, as a WoT protocol, is used as a communication protocol so that the controlling and monitoring system Smart Home can run in real time. To support the system to remain safe in the exchange of data and in the management of devices connected to the system, JSON Web Tokens are also used. Based on the results of implementation and testing, it is evident that the system has a delay of 1 millisecond, while the most optimal response time is when the NodeMCU sends 10 data at a time to a server that only takes 1 second. In addition, LED actuator devices and fans can function properly according to orders obtained from users through a web application.

Abstract

MANET is a set of mobile nodes that exchanges the information from the source to destination nodes by utilizing wireless networks. Each node in MANET can apply as a host or router, wherein each node can determine the path to other nodes on a network. Reactive and proactive protocols are the types of routing protocols which most often used in the scope of MANET network. In this research, researcher used a scenario of variations in the number of nodes, variations in packet size and node speed that would be simulated using Network 2.35 Simulator in MANET areas. The Quality of Service (QoS) parameters used in this study are end to end delay, routing overhead, packet delivery ratio and energy consumption. Based on the result of simulation, indicate that AOMDV has better performance on end to end delay and packet delivery ratio parameters, while FSR has better grade on routing overhead and energy consumption. The average grade of the AOMDV end to end delay and packet delivery ratio is 475,941 s and 38,246%, and the grade of routing overhead and FSR energy consumption are 84151.4 packet and 591.6 joules.
