IoT devices are constrained in computation and storage, therefore cannot store all long-term obtained data or perform complex computations. Shifting those jobs to cloud platform are feasible, yet rising heterogeneity and security issues. This study proposes an IoT cloud platform to facilitate communication among heterogeneous devices and the cloud...

Budidaya ikan Koi semakin berkembang karena stabilnya nilai jual dan jumlah penggemarnya. Salah satu daerahyang secara geografis memiliki kesesuaian untuk mengembangkan budidaya ikan Koi adalah Blitar. Produksi ikan Koi yang dihasilkan oleh pembudidaya di Blitar terkenal memiliki kualitas yang tidak kalah dibandingkan dengan Koi yang yang berasal d...

Sensor data acquisition is used to obtain sensor data from IoT devices that already provide the required sensor data. To acquire sensor data, we can use Bluetooth Low Energy (BLE) protocol. This data acquisition aims to process further data which will later be sent to the server. Bluetooth Low Energy (BLE) has an architecture consisting of sensors,...

Smart Health Care System has been developed massively in the last decade. Internet of Things implementation has accelerated the development of smart health technology. Now people have realized the importance of doing independent health monitoring. Supported by more affordable e-health tools, motivation in using the smart health system is increasing...

At the end of December 2019, the virus emerges from Wuhan, China, and resulted in a severe outbreak in many cities in China and expanding globally, including Indonesia. Indonesia is the fourth most populated country globally. As of February 2021, Indonesia in the first rank of positive cases of COVID-19 in Southeast Asia, number 4 in Asia, and numb...

The increasing number of Koi ornamental fish interested around the world, this fish farming business is increasingly developing. Blitar is one of the geographically suitable areas to develop Koi fish farming. The resulting production has a quality of Koi better than from other countries. Cultivation models and techniques developed are also increasi...

In IoT-based smart healthcare services, the heterogeneity of connected wearable sensing devices open up a wide opportunity to develop various healthcare services. However, it also poses an interoperability challenge since each sensing device and application may have different communication mechanisms. Considering that challenge, web platform can be...

Data inconsistency between government institutions is a common problem in Indonesia. Web technology can solve this problem by synchronizing the data between government institutions quickly and efficiently avoiding inconsistent data among government institutions. Therefore a design of high availability web server cluster is needed. This research pro...

p>Salah satu faktor penting yang berpengaruh terhadap kesuksesan perikanan budidaya adalah aspek kualitas air kolam yang tergambar pada beberapa parameter fisik antara lain suhu, derajat keasaman (pH), oksigen terlarut maupun kekeruhan air. Sebagai tempat hidup ikan, perubahan parameter fisik tersebut dapat berpengaruh secara langsung terhadap pert...

The use of shortest path algorithms for routing a packet in the network has a tendency to elect only one single best path, even though there are several paths that have same best path criteria. Using only one best path may cause a bottleneck in the networks. This paper proposes a method to utilize multiple best path based on link utilization in ord...

Vehicle positioning plays an important role in the design of protocols, algorithms, and applications in the intelligent transport systems. In this paper, we present a new framework of spatiotemporal local-remote sensor fusion (ST-LRSF) that cooperatively improves the accuracy of absolute vehicle positioning based on two state estimates of a vehicle...

An effective and secure authentication mechanism is one of the important part in implementation of communication protocol in a Internet of Things (IoT) based system. As one of the popular messaging protocol in IoT world, Message Queue Telemetry Transport (MQTT) offers a basic authentication using username and password. However, this authentication...

Massive volume and heterogeneous data are the challenges in IoT data storage. A properly designed IoT middleware is required to handle the issues. This paper presents a framework consists of Internet Gateway Device (IGD) function, a Web service, NoSQL database, and IoT Application. The framework efficiently handles the structured and unstructured o...

Reducing the road accident rate is one of the city goal in the area of transportation. One of the effort to reach that goal is done by deploying various signs across the road. However, the role of those road signs can be diminished once the vehicle drivers intentionally or unintentionally disobey the rule indicated on those signs. In order to incre...

One of the most popular algorithm in processing internet data i.e. webpages is page rank algorithm which is intended to decide the importance of a webpage by assigning a weighting value based on any incoming link to those webpage. However, the large amount of internet data may lead into computational burden in processing those page rank algorithm....

In vehicular localization, there is an increasing interest in the fusion algorithm between the relative local sensing estimate (LSE) of ranging sensors and the absolute remote sensing estimate (RSE) of a GPS receiver. A challenging issues of the fusion algorithm is to find a matched pair corresponding to the same vehicle between two sets of estimat...

A vehicle localization technology is an essential component to support many smart-vehicle applications, e.g. collision warning, adaptive cruise control, and so on. In this paper, we present a new vehicle localization algorithm based on the fusion of the sensing estimates from the local sensors and the GPS estimates from the inter-vehicle communicat...

In vehicular safety applications, a vehicular positioning algorithm plays a crucial role in preventing road accidents through the perception of a dangerous situation in advance. However, most of vehicular positioning devices, e.g. a low-cost GPS receiver, have too large position error to be used for these applications. To reduce this error, we pres...

In vehicle-to-vehicle (V2V) communications, each vehicle should periodically disseminate a beacon message including the kinematics information, such as position, speed, steering, etc., so that a neighbor vehicle can better perceive and predict the movement of the vehicle. However, a simple broadcasting of such messages may lead to a low reception p...

In many active safety applications, each vehicle must periodically disseminate a beacon message including the status information, such as position, speed, steering, etc., so that a neighbor vehicle can better perceive and predict the kinematics of the vehicle sending this message.
