Abstract:

The design of wireless sensor network for structural health monitoring systems requires high sampling rate, real-time communication, low-energy consumption, particularly in large-scale networks. However, some commonly available architecture and protocols are not fully suitable for this special application. In this paper, the requirements of wireless sensor network for structural health monitoring application is studied and a two-tiered architecture network where is an IEEE 802.11 wireless local area network on top of an IEEE 802.15.4 structure area network is proposed as a solution.

Abstract:

Lifetime optimization is one of the key issues among the many challenges of wireless sensor networks. The introduction of a small number of high-performance relay nodes can effectively improve the quality of the network services. However, how to deploy these nodes reasonably to fully enhance the network lifetime becomes a very difficult problem. In this study, a modified and enhanced Artificial Bee Colony is proposed to maximize the lifetime of a two-tiered wireless sensor network by optimal deployment of relay nodes. First, the dimension of the problem is introduced into the candidate search

Abstract:

We propose a clustering scheme for wireless sensor nodes in hierarchical wireless sensor networking architectures that employs mobile relay nodes in order to achieve energy conservation and network lifetime prolongation. The key aspects of our scheme are relay node relocation and reclustering when failures are detected.

The results show significant energy savings in particular for topologies with large numbers of senso

Privacy-preserving data queries for wireless sensor networks (WSNs) have drawn much attention recently. This paper proposes a privacy-preserving MAX/MIN query processing approach based on random secure comparator selection in two-tiered sensor network, which is denoted by RSCS-PMQ. The secret comparison model is built on the basis of the secure comparator which is defined by 0-1 encoding and HMAC. And the minimal set of highest secure comparators generating algorithm MaxRSC is proposed, which is the key to realize RSCS-PMQ. In the data collection procedures, the sensor node randomly selects a

Abstract:

Data collection should take reliability and delay into consideration. To address these problems, a novel variable width tiered structure routing scheme named variable width tiered structure routing (VWTSR) is proposed. The proposed VWTSR scheme integrates two core phases, namely, circular tiers and cells partition, and distributed in-network aggregation. The key idea of VWTSR is to partition the network into circular tiers with different widths and each tier is further partitioned into cells. Those cells that do not interfere with each other could simultaneously finish data aggregation by broa

We provide evidence of a novel two-tiered mechanism of PKC action: 1) PKC activity enhances myosin II regulatory light chain phosphorylation and C-

Many of these critics suggest that people need to work together, across traditional identity lines, to solve the problems brought about by today's global economy.

Abstract:

IntroductionWomen and girls are affected significantly in both sudden and slow-onset emergencies, and face multiple sexual and reproductive health (SRH) challenges in humanitarian crises contexts. There are an estimated 26 million women and girls of reproductive age living in humanitarian crises settings, all of whom need access to SRH information and services. This systematic review aimed to assess the utilisation of services of SRH interventions from the onset of emergencies in low- and middle-income countries.MethodsWe searched for both quantitative and qualitative studies in peer-reviewed

Abstract:

278 Background: Regular distress screening of patients with cancer is mandated by cancer care guidelines, with 25-50% of patients with cancer experiencing some level of distress. The COVID-19 pandemic amplified symptoms of distress and shifted oncologic care delivery towards telemedicine. In light of challenges faced with implementation of such screening, especially during this pandemic, we sought to assess the feasibility of implementing patient-focused distress screening at a large academic cancer center and its associated network sites. Methods: We designed a modified distress screening too
