In this paper the description of FlexEye - a visual sensor mote suitable of functioning as super node in the static wireless sensor networks is provided. With mobility features added on to FlexEye, the platform can be used as high performance mobile node in mobile wireless sensor networks or as a node in swarm robotics. A comparison of FlexEye with existing camera platforms developed for sensor networks is made on parameters like processing capabilities, power consumption, cost, time to prototype, support for future expansion, etc. The paper elaborates on the custom off the shelf hardware components used in design and the resource pipelined image acquisition technique implemented on the FlexEye mote for acquiring the high resolution images in real time using minimalistic resources. The paper also provides quantitative details on the achieved frame rates and power consumption details of the FlexEye platform.

In this study, a method to uncover levels of consciousness using electroencephalogram (EEG) coherency and artificial neural network is presented. The subjects of interest are complete locked-in syndrome (CLIS) patients. These patients are characterized by complete paralysis and sufficiently intact cognition. Consequently, they are aware of themselves and their surroundings, but are unable to produce speech. A great challenge in the study of consciousness in patients with CLIS is that there are no certainty regarding their level of awareness at all time. In this paper, a method using EEG coherence matrices as input to a convolutional autoencoder to determine a patient’s level of consciousness is presented. The ultimate goal of the research is to build a brain–computer interface-based communication device to allow interactions with CLIS patients. © Springer Nature Singapore Pte Ltd 2021.

The periodic defected ground structure (PDGS) has been proposed in this work to diminish high mutual coupling of antenna components. The PDGS is always periodically etched on the bottom ground plane along x-axis, placed at the center of the two neighboring patches with side-by-side distance of 0.025λ (λ free space wavelength). Both PDGS and antenna elements are not coplanar, working at the center frequency 5.8 GHz. By inserting a compact PDGS structure at the ground plane facing the center of the two patches, over 50 dB of coupling between adjacent antennas is suppressed within the effective operating frequency range of 5.7–5.9 GHz, achieving low coupling and compact type in the antenna arrays. © Springer Nature Singapore Pte Ltd 2021.

Due to openness of the deployed environment and transmission medium, Wireless sensor networks (WSNs) suffers from various types of security attacks including Denial of service, Sinkhole, Tampering etc. Securing WSN is achieved a greater research interest and this paper proposes a new secure routing strategy for WSNs based on trust model. In this model, initially the sensor nodes of the network are formulated as clusters. Further a trust evaluation mechanism was accomplished for every sensor node at Cluster Head level to build a secure route for data transmission from sensor node to base station. Here the trust evaluation is carried out only at cluster head and also the cluster head is chosen in such a way the node having rich resources availability. The trust evaluation is a composition of the social trust and data trust. Simulation experiments are conducted over the proposed approach and the performance is measured through the performance metrics such as network lifetime, and Malicious Detection Rate. The obtained performance metrics shows the outstanding performance of proposed approach even in the increased malicious behavior of network. © 2019 IEEE.

Multievent wireless sensor networks (WSN) require different levels of reliability and latency based on event types. Besides that, energy efficient consumption is one of the crucial requirements for most WSNs because sensors have limited power and processing capability. Most of researches in this area have dealt with one or two of the requirements. This paper proposes a novel solution combining of energy aware, event driven routing protocol, and dynamic delivering scheme to support the requirements for multievent WSN. Simulation results show that, the proposed solution reduces packet loss rate for high reliability requirement events and extends the network lifetime of multievent WSN. Moreover, in case of high traffic conditions, sharing load across multiple paths would reduce latency for the urgent events in the multiple events network.

One of the main challenges in the wireless sensor networks (WSN) is to enhance the network lifetime. The uneven energy depletion phenomenon of the sensor nodes (known as Hotspot issue) gets more prominent with the increase in number of sensor nodes. These sensor nodes disperse their energy quickly and finally die down. Their battery replacement is not practically possible in the operating environments. Various methods have been put in use to prolong the network lifetime, among which EASR (Energy Aware Sink Relocation) is being considered to be the most efficient one. This paper brings out an overview of these various methods and suggests a modification to the EASR method aimed at increasing its efficiency by way of decreasing the energy consumption of sensor nodes as well as achieving a highly secured communication among sensor nodes using Elliptical Curve Cryptography. Based on the established principle that energy consumption is inversely proportional to the distance between an individual sensor node and sink node, we have suggested a technique of alternate shortest path between the individual sensor nodes that improves energy efficiency as well as the lifetime of overall network system. The present write-up entails some numerical and theoretical calculations that amply substantiate the fact that the idea is practicable.

Wireless Detector Network may be a major and extremely attention-grabbing technology utilized in numerous applications like monitoring the inaccessible conditions in a very specific space. Every detector node consists of A battery, transmitter, receiver and a processor. Exchange or recharging the battery isn't potential. So increasing the network lifetime by reducing the consumption of energy levels of all the detectors and leveling consumption of energy level at each detector are the most challenges within the analysis of the routing protocols in Wireless sensor networks. During this paper, associate Energy consumption clump for wireless detector networks victimization Hybrid Firefly algorithm (HFA) is enforced at the base station (BS). A cost value operate has been outlined to reduce the space between the clusters to optimize the consumption of energy level of the network. The performance is compared with the protocols like LEACH and PSOC.

In this paper, a new architecture design of remote access system for underwater acoustic sensor networks is proposed. This design of architecture contains a band-pass filter characterized by ultra low power consumption and high-sensitivity, which is appropriate for signal inception under low signal to Noise Ratio. The security of the system is enhanced by means of Direct Sequence Spread Spectrum that can prevent unauthorized users from using the networks. In order to further reduce power consumption of the system, 'sleep-wake' mode is applied. Test of the entire prototype system in anechoic tank shows that the system has steady performance, and achieves good performances of low power, long distance transmission and security. The system can not only realize long-distance access of underwater acoustic sensor networks but also offer an approach for sensor networks safely and reliably. © 2010 IEEE.

The recent advances in sensor technologies have made these small, tiny devices much cheaper and convenient to use in many different applications, for example, the weather and environmental monitoring fields, the hospital and factory operation sites, on the traffic road and moving vehicles and so on. Data loss and corruption is inevitable in wireless sensor networks due to the wireless interference, limited sensor power and outlier from malicious electronic devices and so on. Therefore, before processing sensor data in different wireless sensor network applications, certain data cleaning steps need to be performed to ensure the data quality, such as dealing with outliers, missing sensor readings, and noisy data. In this paper, we discuss the issues need to be considered in the data cleaning steps of this integrated data cleaning model for signal processing in wireless sensor networks. We also present an integrated model for data cleaning on signal processing systems in wireless sensor network to deal with different data cleaning problems. © 2010 IEEE.
