One solution for interoperability issue in IoT is a middleware which is competent on resolving the problems of syntactical, semantic, and network interoperability. In previous study, a middleware capable of addressing semantic and syntactical interoperability challenges has been developed, yet has not responded to network interoperability matter. In this paper we continue our previous research by adding BLE and 6LoWPAN features to the middleware's communication media, so it may communicate with various devices. Interoperability test results show that the middleware is capable of responding to network interoperability challenges and able to receive data from multiple nodes simultaneously.

Internet of Things (IoT) connecting sensors or devices that record physical observations of the environment and a variety of applications or other Internet services. Along with the increasing number and diversity of devices connected, there arises a problem called interoperability. One type of interoperability is syntactical interoperability, where the IoT should be able to connect all devices through various data protocols. Based on this problem, we proposed a middleware that capable of supporting interoperability by providing a multi-protocol gateway between COAP, MQTT, and WebSocket. This middleware is developed using event-based architecture by implementing publish-subscribe pattern. We also developed a system to test the performance of middleware in terms of success rate and delay delivery of data. The system consists of temperature and humidity sensors using COAP and MQTT as a publisher and web application using WebSocket as a subscriber. The results for data transmission, either from sensors or MQTT COAP has a success rate above 90%, the average delay delivery of data from sensors COAP and MQTT below 1 second, for packet loss rate varied between 0% - 25%. The interoperability testing has been done using Interoperability assessment methodology and found out that ours is qualified.

An Internet of Things (IoT) middleware can solve interoperability problem among “things” in IoT infrastructure by collecting data. However, the sensor nodes’ data that is collected by the middleware cannot be directly delivered to cloud applications since the sensor nodes and the middleware are located in intranet. A solution to this problem is an Internet Gateway Device (IGD) that retrieves data from the middleware in intranet then forwards them to cloud applications in the internet. In this study, an IGD based on cellular network is proposed to provide wide-coverage internet connectivity. Two test scenarios were conducted to measure delay and throughput between the IGD and the cloud application; using data from DHT22 sensor and image sensor respectively. The results of the first test scenario using DHT22 sensor show that the average delay is under 5 seconds and the maximum throughput is 120 bps, while the second one using image sensor concludes that the average delay is 595 seconds and the maximum throughput is 909 bps.

Abstract. Internet becomes critical infrastructure in the distribution of information. The information is used for decision making and ensure the success of human activities. However, the distribution of information in rural Indonesia is inconvenient, because the digital communication infrastructure (internet) doesnâ€™t cover all areas in Indonesia. This problem causes the digital divide in Indonesia. This study proposes communications infrastructure and data transfer mechanism or media sharing that can be applied to a variety of rural areas conditions in Indonesia, which has limited communications infrastructure. The approach is to build low power digital carrier devices in the form of minicomputer and utilize Delay or Disruptions Tolerant Network (DTN) architecture. Testing results in the digital carrier node show that the data is successfully delivered. Keywords: Rural Area, Mini-PC, Delay Tolerant Network

The use of Internet of Things (IoT) plays an important role in supporting wireless communication for middleware in collecting data sensors. An actor-based middleware is designed to bridge protocol differences between cloud and sensor nodes. This middleware also acts as an initiator in accessing data from several sensor nodes, and then sending data that has been collected to the cloud. Incorporating the differences of communication protocols and data formats between sensor nodes and cloud is the responsibility of middleware. This Middleware acts as an actor by acting proactively accessing data from each sensor node, so that it can facilitate the completion of sending data from the sensor node to the middleware by avoiding from "signal collisionsâ€ among sensor nodes. After the data is collected in the middleware, the data is sent to the cloud using the Websocket or HTTP protocol above the TCP / IP protocol. The performance of the system is evaluated based on the success of the middleware bridging communication between sensor nodes and the cloud, as well as the readability of IoT data sensors that have been adjusted by cloud. The test results show that built-in middleware can bridge protocols between cloud and sensor nodes. In addition, the Websocket usage protocol produces a lower delay value than the MQTT and CoAP protocols.

AbstrakAkses terhadap informasi menjadi kebutuhan yang sangat penting bagi manusia. Namun, tidak semua daerah memiliki akses yang layak terhadap informasi terutama daerah terpencil dikarenakan keterbatasan infrastruktur komunikasi. Teknologi wireless mesh network (WMN) dapat menjadi salah satu solusi untuk mengatasi masalah keterbatasan infrastruktur tersebut. Untuk meningkatkan performa WMN, maka perlu adanya rancangan mekanisme pengiriman informasi yang efisien. Ide penelitian ini pada dasarnya adalah memberikan solusi pengiriman informasi menggunakan arsitektur publish subscribe. Protokol publish subscribe yang digunakan adalah protokol MQTT (Message Queuing Telemetry Transport). Pada penelitian ini dilakukan pengujian terhadap Quality of Service seperti throughput, delay, jitter, dan packet loss untuk keseluruhan node. Pada pengujian QoS arsitektur WMN maupun MTQQ menunjukan bahwa kualitas layanan dipengaruhi oleh jarak,jumlah node yang dilewati dan material yang menghalangi. Seperti yang ditunjukan pada hasil pengujian antara node yang dihalangi tiga tembok beton, packet lossnya mencapai 88.8% dan delaynya sebesar 2.493,79 ms.Kata kunci: wireless, mesh network, publish and subscribeAbstractHas an access to the information becomes a very important requirement for humans. However, not all areas are have adequate access to information, especially in rural areas due to limited communication infrastructures.

Pada penelitian sebelumnya telah dikembangkan sebuah middleware dengan pendekatan event-driven yang mampu mendukung interoperabilitas berbagai macam perangkat sensor pada lingkungan IoT. Namun, skema komunikasi pada middleware tersebut masih terdapat celah keamanan dan menimbulkan ancaman berupa eavasdropping. Solusi dari permasalahan ini adalah menerapakan mekanisme end-to-end security. Dalam penelitian ini dilakukan penerapan algoritme kriptografi AES-CBC 128 pada komunikasi node sensor ke middleware dan mekanisme TLS pada komunikasi middleware dengan aplikasi berbasis IoT. Hasil yang didapat end-to-end security berbasis kriptografi pada pub/sub dapat menjamin kerahasiaan data dengan enkripsi payload akan tetapi topik masih terlihat, sedangkan TLS/SSL menjamin kerahasiaan seluruh data yang dikirim. Penggunaan mekanisme ini tidak berdampak signifikan pada delay pengiriman data, yaitu masih dibawah 1 detik AbstractAn IoT middleware for handling interoperability is proposed in previous works. However, a vulnerability that can lead to the eavesdropping attack exist. there is no security mechanism in the communication system among middleware with other parties like node sensors and subscribers. This research implements the end to end security to the existing IoT middleware. AES-CBC 128 is used to secure communication between sensor nodes to middleware and used TLS/SLL between middleware and subscriber. The results show both mechanisms can securely communication between middleware and other parties, but AES-CBS can only secure data payload, not entire data. This mechanism has no significant impact on the delay transmission, which is still under 1 second
