Wireless Sensor Network (WSN) is one of the key technologies 21st century, while it a very active and challenging research area. It seems that in next coming year, thanks to 6LoWPAN, these wireless micro-sensors will be embedded everywhere, because 6LoWPAN enables P2P connection between nodes over IPv6. Nowadays different implementations stacks are available so interesting evaluate their performance term memory footprint compliant with RFC4919 RFC4944. In this paper, we present survey on...

<title>Abstract</title> Frame selection is a fundamental issue in video action recognition. It aims to minimize temporal redundancy and reduce computational cost. Current frame sampling strategies either rely on uniform based motion, lacking emphasis discriminative frames, or employ complex learning models additional modal information, compromising generalizability. To address these challenges, this paper presents an adaptive strategy. filters redundant frames through motion information...

Large Language Models (LLMs) are discovered to suffer from accurately retrieving key information. To address this, we propose Mask-Enhanced Autoregressive Prediction (MEAP), a simple yet effective training paradigm that seamlessly integrates Masked Modeling (MLM) into Next-Token (NTP) enhance the latter's in-context retrieval capabilities. Specifically, MEAP first randomly masks small fraction of input tokens and then directly performs standard next-token prediction autoregressive using...

Background Pediatric cardiomyopathies are rare but life-threatening conditions with high mortality. Limited data exists on their clinical features and risk factors, especially in Asian populations, highlighting the need for further research this area. Methods This retrospective cohort study analyzed from 212 pediatric patients diagnosed hypertrophic cardiomyopathy (HCM), restrictive (RCM), or phenotype (RP-HCM) at a single center China October 2012 to 2023, follow-up until 31, 2024....

This paper focuses on the routing protocol for driving safety that vehicle collects state message from roadside sensors in VANET-WSN. Routing Protocol Low Power and Lossy Networks (RPL), a tree-based protocol, adapts naturally to our requirement. But RPL is designed static wireless sensor network, so we need modify fit with high dynamic topology of For first time, utilize Geographical Information (GI) as metric (GI-RPL), which lets timely fashion. We also propose some strategies tuning To...

Vehicular Ad hoc Networks (VANETs) aim to improve transportation activities that include traffic safety, transport efficiency and even infotainment on the wheels, in which a great number of event-driven messages are needed disseminate region interest timely. However, due nature VANETs, highly dynamic mobility frequent disconnection, data dissemination faces challenges. Inter-Vehicle Communication (IVC) protocols key technology mitigate this issue. Therefore, we propose an infrastructure-less...

With the development of communication networks and widespread use mobile terminals, videos are increasingly shared distributed among users. During process, video is recompressed to a certain file size on sending side sent receiving via server. This makes robust watermark with low complexity resist recompression attacks become an important issue address. The proposed watermarking method in this article specially designed for resisting when quantization parameter (QP) greatly increased. In...

Precision agriculture has been considered as a new technique to improve agricultural production and support sustainable development by preserving planet resource minimizing pollution.

The last few years have seen substantial progress in the field of smart objects (SOs): their number, diversity, performance and pervasiveness all been quickly increasing this evolution is expected to continue. To best our knowledge, little work has made leverage abundance resources develop assistive devices for Visually Impaired People (VIP). However, we believe that SOs can both enhance traditional functions (i.e. obstacle detection, navigation) offer new ways interacting with environment....

Then, considering disturbance uncertainty system model, adaptive thresholds are computed attack. Furthermore, UIO-based Algorithm proposed, computing observed residuals. Finally,...

Abstract:

The Wireless Sensor Networks (WSN), with their constant evolution, need more and practical effective WSN Management Tools (WMT) for large-scale deployment. Due to the resource constraints of wireless sensor node, it is impossible implement full classical SNMP standard in applications.
