Collision avoidance and road safety applications require highly accurate vehicle localization techniques. Unfortunately, the existing localization techniques are not suitable for road safety applications as they rely on the error-proneGlobal Positioning System (GPS). Likewise, cooperative localization techniques that use intervehicle communications experience high errors due to hidden vehicles ...

To detect the position forging attacks in vehicular ad hoc networks (VANETs) and to improve vehicle passenger safety by means of inter vehicle communication. In the existing system, it presents a model for the performance evaluation of safety message dissemination in VANETs with two classes. In particular, considering the IEEE 802.11 broadcast protocol and 2D Markov modelling. Then the result i...

With the development of internet vehicles, traditional centralized content caching mode transmits through core network, which causes a large delay and cannot meet demands for delay-sensitive services. To solve these problems, on basis vehicle we propose an edge collaborative scheme. Road side unit (RSU) mobile computing (MEC) are used to collect information, predict cache popular content, there...

The Internet of Things is made up a set embedded devices such as light detection sensors, ranging (LiDAR) and millimetre-wave sensors. These sensors generate massive amount data in which limited communication capacity available to share Fog-based Roadside Units (RSU) for process analysis service. RSU has become an emerging paradigm intelligent transportation but needs research attention design ...

At the beginning of medical studies at Rīga Stradiņš University (RSU), students’ knowledge and skills differ widely. In first semester, students must take a course, “Molecular Cell Biology.” many cases, problems in abilities to absorb new information this new, specific nature are evident. The reason for is insufficient prior preparation. On average, 3-4 % failed course each academic year. After...

We develop joint vehicle tracking and road side unit (RSU) selection algorithms suitable for vehicle-to-infrastructure (V2I) communications. first design an analytical framework evaluating systems based on the extended Kalman filter. A simple, yet effective, metric that quantifies performance is derived in terms of angular derivative a dominant spatial frequency. Second, RSU algorithm proposed ...

In the current era of BPJS, role and existence type D hospitals is absolutely necessary, especially in a tiered referral system for BPJS participants. This study aims to identify readiness human resources (HR), administration management development XXX pratama clinic into Pratama General Hospital (RSU). uses qualitative methods with operational research. Using analysis primary data secondary da...

This paper presents the dynamic modeling and design of micro motion compliant parallel mechanism with flexible intermediate links and rigid moving platform. Modeling of mechanism is described with closed kinematic loops and the dynamic equations are derived using Lagrange multipliers and Kane’s methods. Euler-Bernoulli beam theory is considered for modeling the intermediate flexible link. Based...

We propose a dissemination system using multiple roadside units (RSUs) on a two-way roadway. To enhance the performance of data services, data items are disseminated through a hybrid of infrastructure-to-vehicle (I2V) and vehicle-to-vehicle (V2V) communications. Unserved requests in RSU’s coverage are transferred to the next RSU located in a vehicle’s trajectory. In this way, channels are utili...
