Therefore, the capabilities of the products must be defined to say that they are compatible enough. This paper aims to evaluate the performance of the DDS-XRCE standard while observing its working mechanism. As test scenarios, we benefit from three DDS-XRCE deployments that occurred due to the kind of receiver and sender, the path that packets follow, and the protocols used. Test conditions were set by switching stream modes, transport profiles, and limiting packet deliveries. We obtained the test environment by creating the DDS and DDS-XRCE objects using several eProsima implementations and tools for the standards. We monitored the network messages in two ways: 1) Using multiple Gnome Terminator terminals for observation via the human eye during testing. 2) Using Wireshark to save the information of the packets for further examination. We conducted 36 experiments focusing on latency, throughput, and packet loss. As a result of our study, the DDS-XRCE standard is deemed suitable for Internet of Things applications.</span></p> Sevval Solpan Kerem Kucuk Copyright (c) 2022 EAI Endorsed Transactions on Internet of Things https://creativecommons.org/licenses/by/3.0/ 2022-11-23 2022-11-23 8 4 e1 e1 10.4108/eetiot.v8i4.2691 Smart Agriculture Solutions for Vietnamese Farmers https://publications.eai.eu/index.php/IoT/article/view/2935 <div><p class="ICST-abstracttext"><span lang="EN-GB">Agriculture is the back bone of Vietnam and more than 70% of people in Vietnam depend on agriculture. Nowadays, agriculture crops are affected due to many environmental changes. To overcome this problem, I design and prototype a wireless sensor and actuator network for smart agriculture application. The aim of this work is to be able to capture useful data to start predicting measurements and events that could help farmers and specialists to save time and money. I propose two solutions for smart agriculture. In the first solution, wireless sensor and actuator nodes monitor multiple environmental parameters and transmit the sensor data to a server via the internet. Users can monitor these environmental parameters from anywhere via the internet. In the second solution, wireless sensor and actuator nodes send data to a local computer. This computer is deployed in a technical room. The experiments show that both solutions operate well in real conditions.</span></p></div> Chien-Thang Vu Copyright (c) 2022 EAI Endorsed Transactions on Internet of Things https://creativecommons.org/licenses/by/3.0/ 2022-12-14 2022-12-14 8 4 e2 e2 10.4108/eetiot.v8i4.2935 Data prediction system in malaria control based on physio-chemical parameters of anopheles breeding sites https://publications.eai.eu/index.php/IoT/article/view/2936 <div><p class="ICST-abstracttext"><span lang="EN-US">Malaria is a public health problem in Senegal.

Currently, these graphics processor are found on all graphics hardware and have become very important instruments for parallel computing. GPUs are practical tools for the development of several fields like decoding and encoding, solving differential equations. Their advantages are increase in performance, faster data processing and reduced power consumption. It is simple to program a GPU with CUDA C to run parallel calculations. But it is necessary to have an understanding of the architectural aspects of the GPU and CUDA C. This paper, we will describe and implement Beeman's algorithm on GPU and CPU using CUDA C to solve the differential equation of charged particles in an electromagnetic field. Our goal is to evaluate the performances of the implementation on GPU and CPU processors and to deduce the efficiency of the use of GPUs.</span></p></div> Youness Rtal Abdelkader Hadjoudja Copyright (c) 2022 EAI Endorsed Transactions on Internet of Things https://creativecommons.org/licenses/by/3.0/ 2022-12-15 2022-12-15 8 4 e4 e4 10.4108/eetiot.v8i4.2937 Smart Cane: A Low Cost Assistive Device for the Visually Impaired https://publications.eai.eu/index.php/IoT/article/view/1707 <p class="ICST-abstracttext"><span lang="EN-GB">Vision impairment or low vision is the disability to see any objects clearly. It might be caused by old age, an accident, or any other neurological condition. People find it difficult to carry out their regular activities, regardless of the cause of their vision impairment or blindness. As medical researchers are working to find a cure for blindness, contrariwise researchers are using technology to make a vision impairment person’s life easier in an affordable way. As a result, a smart cane was developed, although it is expensive for most of blind people. The main objective of this paper is to introduce an affordable smart cane for every visually impaired person. The ultrasonic sensors in this walking stick are used to identify impediments. This system is using an arduino to reduce the processing time between receiving and delivering signals created by ultrasonic sensors. The speech output will guide a blind person to take a safe path making the stroll more comfortable and secure.</span></p> Wohiduzzaman Kazi Taslima Jannat Limu Md.
