In recent years, a vast researches are concentrated towards the development of EEG based human computer interface in arrangement to enhancing the quality of life for medical as well as non-medical applications. Industry and community of research has been attracted by wireless EEG devices and they are easily available in the market. Such technology can be incorporated to psychology, anesthesiology,...
Wireless sensor networks (WSNs) are collection of sensor nodes that unite together to monitor an environment or a system. Due to abundant workload on node near the sink makes faster energy depletion than other nodes. Due to this, lifetime of WSNs to some amount, is resolved by the power consumption between sensor node & sink. Hence, CSMA/SF is used to reduce power consumption for sensing nodes...
In the process of Multi-UAV (Unmanned Aerial Vehicles) perform the task, with the increasing of detection range, how to decrease the communication range of the UAVs group to prevent the eavesdropping of information, which is an urgent need to solve the problem of Multi-UAV secure communications. In this paper, a distributed cooperative control algorithm improved by UAVs-transmission-power-setting-based...
Beacon allows Bluetooth [1] devices to broadcast and receive tiny information within short distance, which consists of two parts: a broadcaster (beacon device) and a receiver (smartphone app). So, it is being widely used in URL (Uniform Resource Locator) broadcast, distance measurement, localization etc. However, because of its deviation, measured distance value is not always accuracy. In this paper,...
Owing to the slow circuit board level maintenance and fault location of wireless communications equipment, and technically demanding problems, the multi-state circuit board testing environment was establish to study the circuit board interface type, input and output signals, power supply and others. Based on the diagnostic strategies of multi-signal flow model optimization design, this paper designed...
Impulsive noise is one of the key factor that prevents millimeter waves frequencies wireless sensors system to be fully reliable in the railway environment. Measurements of impulsive noise taken in real railway environment are required to understand the behavior of the wireless sensors under these undesired fields. In this paper, impulsive events are extracted and characterized from the measured data...
This paper presents a novel origami quadrifilar helical antenna (QHA) that can reconfigure its operating frequency between 2.07 GHz, 3 GHz and 4.45 GHz. An origami reflector was designed to enhance the gain of the QHA for all the operating frequencies. Typical simulated realized gains of this origami QHA with reconfigurable reflector are 15.13 dB at 2 GHz, 12.82 dB at 3 GHz and 15.13 dB at 4.45 GHz.
A Polarized OFDM (POFDM) scheme is proposed for the wireless depolarized channel. Through such scheme, each sub-carrier's polarization state, amplitude and phase can be modulated to bear information, and the spectrum efficiency can be further improved. Consider the multi-path fading channel, the channel caused depolarization impairments to POFDM are quantitatively analyzed; to mitigate such impairments,...
In the literature, performance of a wireless system has been evaluated for uniformly distributed users. To efficiently evaluate the performance of a wireless system, we should emulate the distribution of users as the most likely occurring in real life. In many real-life cases, the distribution of users is considered to be Gaussian. In this work, we evaluate the probability density function (PDF) of...
Broadcast Services is one of the most anticipated Internet services. Different from the conventional client-server based ones, information is provided to certain users according to some criteria for avoidance of wasted bandwidth and processing power. Location based broadcasting has been proposed; however, gain from most information is time-dependent and broadcasting schedule is determined based on...
Technical communities are social structures that emerge around the interest of individuals to build and deploy their own technology or communication infrastructure, such as wireless community networks. In these communities, the access to shared resources is regulated by incentive mechanisms, which are usually based on the members' contributions. Typically, technical contributions are computed by these...
Internet of Things in which object, animal, people is identified uniquely according to their identifier in the network and data transfer over Network without having directly human to human or human to machine interaction. IoT is used in education to improve E-Learning. It is available in different formats. Propose a system combining the different applications of e-learning with the help of Internet...
A Wireless Mesh Network (WMN) is a collection of wireless mesh nodes that communicates with each other without using any existing infrastructure, access point or centralized controller. In WMN, as nodes moves in and out of the network, the topology of the network changes frequently and thus, routing becomes a challenging task. A variety of routing protocols with varying network conditions are analyzed...
The IEEE INFOCOM community has looked to large-scale computer networking testbeds such as PlanetLab, Emulab, and ORBIT to fulfill an essential role in the testing and validation of innovative ideas. Until very recently, testbeds such as these have existed in separate silos, each with its own authentication mechanisms and experiment support tools. The OneLab experimental facility breaks down the barriers...
Mobile ferries are an alternative way for collecting data from dispersed sensor nodes especially in large-scale networks. Unlike data collection via multi-hop forwarding among the nodes, ferries travel across the sensing field and collect data from the sensing nodes. The advantage of using a ferry based approach is that, it eliminates the need for multi-hop forwarding of data, and as a result energy...
With the day to day advancements in technology, the interaction between the human and the digital world is diminishing. Lot of improvement has taken place in the mobile technology from button keypads to touch screens. However the current PCs still need a pad to operate its mouse and are wired most of the time. The idea is to develop a wireless mouse which works on the hand gestures of the user without...
In this world where every operations performed by human are getting simple, in order to make it more simpler I present an innovation which makes use of human GESTURE, the very definition of being human. This paper deals with human gesture application, in this paper a Hand Signal Transceiver system will introduce for military soldiers. It is based on hand gestures which will be useful for squad communication...
The development of a wearable recording system to acquire L-glutamate (L-Glu) neurotransmitter signals from the central nervous system (CNS) was reported. The system utilized miniature (50×100 μm2) implantable amperometric sensors fabricated on a flexible polyimide substrate to minimize in vivo tissue damage. Selectivity to L-Glu was improved through implementation of self-referencing electrode and...
Positioning is the foundation of wireless sensor applications. An attack method of multiple counterfeit identities in sensor network localization is proposed. At different times, attack nodes counterfeit different identities nodes, sending false reference coordinates, which leads to the failure of positioning. In the paper, we establish a normal localization system, which can accurately calculate...
