Abstract

Internet of Things (IoT) is a network of things which able communicate about surrounding information with other things by using simple computer, communication device, and censor without the need of human interaction. Generally the data in the network will be collected to a main computer which will be processed and send to the data centre using internet connection. However in the case where there is no internet infrastructure the data cannot be send to data centre. Hence the development of mobile application which can be used to gather and bring the data to area with internet infrastructure and send it to the data centre. To help the process of the data delivery the developed application has a feature to be able to send data to other mobile device without using internet connection using WiFi-Direct. To handle multiple data transmission, in the case the courier of the data meet more than once device, the developed application also implement flooding algorithm where the data will only be sent to the directly connected adjacent which suitable with the WiFi-Direct constraint that is not able to form multi-hop connection. The development of the application is completed using object oriented approach through analysis, design, and implementaion stage. The mobile application has been successfully developed and is able to fulfill all the required functions to solve the problem of sending the data from the field to data centre based on the 100% validation test result from the black box testing. With tested performance of maximum connection range, optimal connection range, total time required to form a connection between mobile application and total time required to send data between mobile application.

Abstract

The rapid development of information technology makes the implementation of Internet-of-Things (IoT) increasingly common in everyday life. The IoT challenge is the ability to support devices with limitations and the Constrained Application Protocol (CoAP) is built to accommodate those problems. CoAP uses a client/server architecture that serves the request and provides the data respond requested by the user. This poses a problem when the client accesses the same resource simultaneously. This situation affects the workflow and makes it inefficient since it must do the same data request for all clients who needs that data. These activities may affect the performance of the server nodes which has limitations, and interfere the data transactions on the CoAP network. Therefore, the solution is by implementing a publish/subscribe architecture on CoAP in an IoT environment. The system uses broker that become bridges between publishers and subscribers, as well as data centers during data transactions. The test results show that the system has been able to run according to its functional needs, and the system has been able to run scalability test scenarios up to 250 users with a 0% error rate and has an average latency value of 74.5% smaller and overhead efficiency is 45.4% better than conventional CoAP. Based on these results, the system can be a solution to the problem of the IoT environment that has limitations.

Abstract

Long Range Wide Area Network (LoRaWAN) is a type of network for wireless telecommunication area designed to enable remote communication with long distance communication and low bit rate. LoRaWAN can be used on communication networks that have a wide range using end devices. LoRaWAN offers a wide range of advantages to the challenge of IoT implementation, but the current implementation of LoRaWAN technology is still very limited, requiring feasibility testing and analysis to what extent LoRaWAN technology is capable of being implemented in urban areas in Indonesia. In this research, an analysis of the performance of the LoRaWAN protocol for data transmission with urban area scenarios in Malang City is carried out. The method used in this study is to simulates LoRaWAN protocol in Network Simulator 3 (NS-3) application by changing the parameters to determine the effect on the the number of end devices, radius of the gateway range, and data sending period to the parameters throughput and packet loss. From the results of research proved that for the use of protocol LoRaWAN in urban areas, the more end devices used, the greater the throughput value and the greater the value of packet loss obtained. In addition, the wider the area needed, the throughput and packet loss obtained are constant. And then, the larger the period of data transmission, the smaller the throughput value is obtained and the smaller the value of packet loss obtained.

Abstract

Healthcare is one of the interesting fields in the application of IoT. However, the devices used in the implementation of IoT-based healthcare are very heterogeneous, this is a challenge for application developers to overcome the different communication mechanisms in sensing devices. In addition, the IoT application requires batch and stream data processing. Based on these challenges and requirements, the authors develop middleware to overcome these challenges. Middleware consists of three components it is sensor-to-cloud gateway components, messaging services, and data access interfaces. After implementation we perform device management, sensor-to-cloud gateway, messaging service, batch interface and stream interface test. Device management testing shows that the gateway component is able to manage sensor devices using BLE. Sensor-to-cloud gateway testing shows the ability of the gateway to forward sensor device data to the cloud. The messaging service test shows the ability of middleware to store messages in a database and facilitate the access stream interface. In batch and stream testing it can be seen that middleware can provide data for client users in batch and stream.

Abstract

Wireless Body Area Network (WBAN) is a wireless network technology that designed to monitor vital signs of human body health. WBAN could remotely check a patient's health condition so that the patient still be able to move freely. However, WBAN sensor devices has resource limitation such as communication capability, computational power, available memory and storage. One primising solution to the problem of process and manage large amount of medical data is to use cloud computing platform. However, WBAN sensor devices are mostly doesn't have ability to connect to internet. In this research, we proposed a gateway to connect between WBAN and cloud storage. The gateway is developed in a mobile platform so that the patient has mobile capability. The gateway also has store-forward mechanism to store and forward the data temporarily when the gateway doesn't have internet connection or lack of network infrastructure. ECG sensor (AD8232) is used in this research. Bluetooth Low Energy is used for sensor-gateway connection and MQTT for gateway-cloud connection.

Abstract

Software-defined network (SDN) provides a promising architecture for future networks and can benefit from programmability on the controller to manage all behavior on the network. Apart from the advantages SDN has, there are challenges to SDN network security. Distributed Denial of Service (DDoS) is one of the attacks that can attack components that exist on the SDN architecture. In this study the detection and mitigation system of DDoS attacks was built to minimize DDoS attacks on SDN architecture using SVM Classifier. SVM is applied to the machine learning model to classify normal traffic and DDoS attack traffic based on features taken from flow entries. From the test results the system has been able to detect DDoS attacks with an average accuracy of 96.83% and an average detection time of 67.80 ms. In addition, the system can also reduce the number of DDoS attack packets sent to the victim host.

Abstract

The large amount of data generated from Internet of Things (IoT) devices makes cloud computing widely used as IoT data storage. Cloud computing which has full access control over IoT data, causes a limitation where users are unable to fully manage and monitor the data they have. Users also can not know the integrity of each data. Therefore, we need a system that can store IoT data while also giving users more access control in managing and monitoring their data. On the other hand, blockchain, a technology with a decentralized architecture that has a consensus mechanism, is able to guarantee the integrity of any data stored without centralized authority. With these advantages, it is expected that the blockchain can become an alternative solution in managing and storing IoT data. In this study, the integration between the Internet of Things and the blockchain is to develop a gateway as an intermediary in terms of sending sensor data. The results of this study is gateway is able to receive data from sensor nodes, manage data structures and send them to the blockchain network. In addition, the authentication mechanism was also successfully provided in order to validate the gateway as a form of limiting access to the blockchain network. Finally, the measurement of gateway performance gives a success rate of 100% and an average processing time of 0.52 ms.

Abstract

Storing medical records on paper cause problems that can make medical records data scattered across various healthcare facility. The problems concerning healthcare facility to use electronic medical records so that they can share the data and increase its availability. Data sharing mechanism raises awareness that data privacy and integrity must be guaranteed. A technology that can be utilized for this problems that arise is blockchain. In this research proposed a medical record system using Hyperledger framework based on permissioned blockchain. The proposed system solves this problem by recording transactions that occur on medical records thus providing data integrity. Recorded transactions will be distributed inside blockchain envinronment so that every hospital has a copy of recorded medical data. Multi user rest server provided by Hyperledger framework is used to prevent unauthorized user accessing stored medical data inside the blockchain. Data availability can be maintained because blockchain keeps a copy of data on each peer. Data privacy can be maintained by using multi user rest server and access control provided by Hyperledger framework. Data integrity can be maintaned because blockchain used consensus mechanism. Performance results on this research shows that increased latency metrics directly proportional to the number of users accessing data inside the blockchain.

Abstract

Smart aquaculture is one of the aquaculture concepts that applies the concept of the Internet of Things (IoT) in monitoring water quality remotely. The components used are sensor nodes, gateways, and clouds. These three components play a role in sending and retrieving water quality data using the LoRa and MQTT communication protocols. LoRa communication is used to send and receive data between the sensor node and the gateway, while communication to connect the gateway to the cloud uses the MQTT protocol. Water quality monitoring has been studied before but still has limitations in certain conditions, where the sensor node and the cloud do not have a direct connection. Then the data transmission from the research cannot be done so an agent as an intermediary sensor node is needed for the cloud. One agent that can be used as an intermediary sensor node to the cloud is the drone. The drone agent is used as a gateway to connect the sensor node and the cloud. There are two tests conducted, namely functional testing and performance testing. In functional testing, sensor nodes that have been implemented successfully retrieve data using temperature, pH, dissolved oxygen, and turbididty sensors. Performance testing is carried out to determine the ability of the system when sending sensor data to the drone agent. Performance testing is measured by sending delay and success ratio parameters with 1hop distance scenario. The results of the 1hop distance scenario test with a drone flight height of 10m from the ground, at 100m distance variation gets an average delivery delay of 523.53 ms with a success ratio of 100%, at 300m distance variation gets a mean shipping delay of 747.43 ms with a success ratio of 100%, at a variation of distance 600m has an average delivery delay of 541.70 ms with a success ratio of 90%.

Abstract

Wireless sensor network is one of the main supporters in the development of the internet of things. One of the most widely used communication modules on wireless sensor networks is LoRa. LoRa has the advantage of being able to communicate over a large area and low power consumption. LoRa has the disadvantage of not being able to send data directly to the cloud server, so a gateway is needed to bridge the transmission. Communication from the gateway to the cloud is using the MQTT protocol. The MQTT protocol was chosen because it is lightweight and easy to use. In previous research has successfully implemented a gateway to bridge the transmission of data from the LoRa communication module to the MQTT protocol. However, it still has the disadvantage of only being able to communicate one way from the sensor node to the cloud. With this research, a LoRa-MQTT gateway is created that can communicate both ways from the sensor node to the cloud and from the cloud to the sensor node. Functionality testing is performed so the system can run as needed. Performance testing is carried out to determine the effect of distance and data size on system performance. The results of performance testing indicate that the longer distance does not necessarily result in a longer data transmission delay. However, it caused a decrease in the data transmission succes ratio.
