Abstract:

Abstract In this study, the performance of the Long-Range (LoRa) communication and 3DR Radio Telemetry modules was evaluated. The suitability of these two communication options was assessed for the application on an autonomous sailboat prototype. The communication range and power consumption of each module are the primary factors for selection. The test results found that LoRa technology can send data stably with a range of up to 10.5 km, while the 3DR Radio Telemetry module can only send data stably up to 300 m. The LoRa technology consumes 9.56 Wh of electrical energy per day for the autonom

Abstract:

LoRa (Long Range) is a long-range communications capacity with chirp spread spectrum modulation. It has been developed for Internet of Things (IoT) applications for long-distance and low power consumption. Some authors proposed LoRa protocols such as LoRaWAN, LoRaBlink, DQ-LoRa and the multi-hop LoRa network with linear topology; however, these protocols have disadvantages. In this paper, we propose a minimized latency multi-hop LoRa network protocol that is collision-free with low latency to improve on the disadvantages. First, in the proposed protocol, tree topology is constructed by exchang

Abstract:

LoRaWAN has gained significant attention for Internet-of-Things (IOT) applications due to its low power consumption and long range potential for data transmission. While there is a significant body of work assessing LoRA coverage and data transmission characteristics, there is a lack of data available about commercially available LoRa prototyping boards and their power consumption, in relation to their features. It is currently difficult to estimate the power consumption of a LoRa module operating under different transmission profiles, due to a lack of manufacturer data available. In this stud

Abstract:

Wireless Sensor Network has an applicative function and a broad discussion area so that it becomes an interesting research topic to discuss. WSN connects communications from several nodes in one network. In order to make each data can be sent, a communication module is needed. LoRa is a communication module that allows each node to make long range communication. However, one of the issues of WSN is that every communication on the node to exchange data uses a time reference from the respective local clock. The difference in time reference in each node will interfere with the process of arrangin

Abstract:

The challenge of detecting nuanced, context-dependent offensive language highlights the need for Large Language Model (LLM) adaptation strategies that can effectively address inherent data and task asymmetries. Standard Parameter-Efficient Finetuning (PEFT) methods like Low-Rank Adaptation (LoRA), while efficient, often employ a more uniform, or symmetric, update mechanism that can be suboptimal for capturing such linguistic subtleties. In this paper, we propose Dynamic Sparse LoRA (DS-LoRA), a novel technique that leverages asymmetric adaptation to enhance LLM finetuning for nuanced offensive

LoRa is a low-power wireless communication technology capable of transmitting data over long distances. LoRa is widely used in embedded systems and the Internet of Things (IoT) in various sectors, such as agriculture, fisheries, industry, transportation, and smart cities. However, the data transmitted through LoRa is not encrypted, so the confidentiality of the data is not guaranteed because the data can be intercepted and read by hackers at the same frequency. Therefore, data encryption techniques are needed in the LoRa system to maintain data confidentiality when transmitted. In this researc
