“…By collecting up-to-date information about the status of the road, the driver/pedestrian assistance system can quickly detect potentially dangerous situations, and notify the driver/pedestrian about the approaching danger. A relatively small reduction in the driver's/pedestrian's reaction time may potentially avoid the trigger of an accident [39].…”

SummaryThe paper presents some commercial ICT (Information and Communication Technology) solutions for increasing workers' safety in invasive environments (e.g., steel industry, mining, construction, oil and gas rigs, seaports, etc.). It has been pointed to the need to increase safety measures, primarily because of the necessity to protect human lives and health, as well as to increase productivity and reduce the costs, which companies and insurance agencies have to cover in the case of accidents. The article also briefly describes some alternative solutions that have been examined at the level of simulations, in accordance to the actual needs and available resources at the Port of Bar (South Adriatic Sea). This seaport has been operating during the decades in the transitional conditions and it has been permanently faced with the impediments in providing sophisticated and expensive ICT solutions for occupational safety purposes. SažetakU radu su prikazana komercijalna ICT (informacijske i komunikacijske tehnologije) rješenja za poboljšanje sigurnosti na radu u invazivnom radnom okruženju (npr. industrija čelika, rudnici, gradilišta, naftne i plinske platforme, morske luke, itd.). Pokazuje se potreba poboljšanja sigurnosnih mjera, ponajprije zbog zaštite ljudskih života i zdravlja, kao i zbog povećanja produktivnosti i smanjenja troškova koje kompanije i osiguravateljske kuće moraju pokriti u slučaju nezgoda. U članku se također ukratko opisuju alternativna rješenja koja su ispitana na razini simulacija u skladu sa stvarnim potrebama i raspoloživim resursima u Luci Bar (južni Jadran). Ova morska luka djeluje desetljećima u uvjetima tranzicije i stalno je suočena s preprekama u pružanju sofisticiranih i skupih ICT rješenja za potrebe zaštite na radu. KEY

Construction Low Complexity and Low Delay CDS for Big Data Code Dissemination

The diffusion of codes is an important processing technology for big data networks. In previous scheme, data analysis was conducted for small samples of big data and complex problems that cannot be processed by big data technology. Due to the limited capacity of intelligence device, a better method is to select a set of nodes (intelligence device) to form a connected dominating set (CDS) to save energy, and constructing CDS is proved to be a complete NP problem. However, it is a challenge to reduce the communication delay and complexity for urgent data transmission in big data. In this paper, an appropriate duty cycle control (ADCC) scheme is proposed to reduce communication delay and complexity while improving energy efficient in CDS-based WSNs. In ADCC scheme, the method for constructing CDS is proposed at lower complexity. Nodes in CDS are selected according to the degree of nodes. Then, duty cycle of dominator nodes in CDS is higher than that of dominated nodes, so the communication delay in the proposed scheme is far less than that of previous scheme. The duty cycle of dominated nodes is small to save energy. This is because the number of dominator nodes in CDS is far less than the number of dominated nodes whose duty cycle is small; thus, the total energy consumption of the network is less than that of the previous scheme. As a result, the performance of energy consumption and communication delay and complex have been improved. Its complexity O ∑ v i=0 m − i + 2m − 2v − s is reduced a lot for big data. The theoretical analysis shows that compared to the previous scheme, the transmission delay can be reduced 25-92% and the energy efficiency is improved by about 80% while retaining network lifetime.

Safety messages propagation is the major task for Vehicular Cyber-Physical Systems in order to improve the safety of roads and passengers. However, reducing traffic and car accidents can only be achieved by disseminating safety messages in a timely manner with high reliability. Although mathematical modeling of the delay of safety messages is extremely beneficial, analyzing the safety messages propagation is considerably complex due to the high dynamics of vehicles. Moreover, most previous works assume vehicles drive independently and the interaction between vehicles is not taken into consideration. In this paper, we proposed an analytical model to describe the performance of safety messages propagation in the VCPSs under platoon-based driving pattern. Infrastructure-less and RSU-supported scenarios are evaluated independently. The analytical model also takes into account different transmission situations and various system parameters, such as communication range, traffic flow, and platoon size. The effectiveness of the analytical model is verified through simulation and the impacts of different parameters on the expected transmission delay are investigated. The results will help determine the system design parameters to satisfy the delay requirement for safety applications in VCPSs.
