Due to the allocation of large contiguous bandwidths in excess of several gigahertz in the mmWave spectrum, mmWave communications plays a key role in the next generation cellular 5G networks. The applicability of simple air interfaces without the need for complex techniques for optimized spectrum utilization make mmWave carrier frequencies a preferred solution to cope with the huge traffic demand...
In order to improve the spectrum efficiency and achieve greener communication in wireless applications, in this paper we propose a novel energy saving strategy in cognitive networks based on software defined radio. By establishing a preemptive priority queue model with single vacation, we capture the stochastic behavior of the proposed strategy. Using the method of matrix geometric solution, we derive...
Detailed procedure for laboratory set up of Miniature Aerial System (MAS) simulator. MAS have three parts viz., Miniature (unmanned) air vehicle (MAV), wireless communication link and ground control station (GCS). For testing, flying MAV every time is more expensive and not viable. To overcome this problem, a laboratory based Miniature Aerial Vehicle Flight Simulator (MAVFS) has been developed by...
Dock emu is developed because of the need for a well designed tool for emulating networks. The tool utilizes technologies that are tailored to a current researcher's needs, delivering a robust and dynamic framework. In the past, most emulation tools have tried to provide solutions without taking into consideration that the installation and configuration of the software can be very time consuming,...
Delayed offloading of mobile user delay tolerant traffic, through other networks such as WiFi networks or millimeter wave (mm-w) gates, is a promising solution for dealing with the ever-growing problem of wireless cellular network capacity. In this paper, we investigate the problem of how we can optimally associate a user with delayed traffic to a nearby offloading zone, i.e., to which nearby offloading...
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...
In order to solve the problem of the traditional intelligent mower, which cannot cover the lawn area and operate complexly, a visual, wireless, autonomous mower system via machine vision is designed. Firstly, collect the image information of locale dynamically by the real-time camera which erected on the high bracket, and display on the monitor of PC, then draw a few mowing range or mowing patterns...
The primary principle of Software Defined Radio based system is to support a multiple wireless communication services in a single system design. The RF transmission supports multiple channel communication. The channelizers used in SDR, extracts expected channels from received RF frequency band and perform baseband processing. This paper proposes the power efficient channelizers for selection of the...
Seamless Presentation (SP) is a server-less sharing system that is targeted to work over WiFi environment. Unlike similar works found in the literature which rely on WiFi Direct devices, SP was designed and implemented purely as software solution to support multi-delivery models. It supports 1-to-1, 1-to-many, and a combination of 1-to-1 with 1-to-many to serve different application scenarios such...
This paper presents the development of wireless light switch system with primary signal carrier band in Sub- GHz. In contrast to conventional wired lighting system, wireless concept delivers much more efficient application in material budget, distance, simplicity and performance. At the other side, application may be better performed with Wi-Fi network of 2.4GHz in terms of worldwide popularity, however,...
This paper presents an experimental deployment of a multi-channel wireless backbone network (WBN) with an Open Flow-based traffic management framework. In a WBN, a set of APs, each of which uses a single and different channel, is connected by Ethernet and thus constructs a VAP handling multiple channels. To flexibly control traffic flow transmitted over multiple channels, we also implement a traffic...
This work presents new experimental results examining the loss tolerant unicast congestion control behavior of the NACK-Oriented Reliable Multicast (NORM) transport protocol documented initially as Internet Proposed Standard, Request for Comments (RFC) 5740. While RFC 5740 specifies a reliable multicast UDP-based transport protocol, NORM also has the ability to provide loss tolerant UDP unicast reliable...
In this work we demonstrate an over-the-air capability to exploit software weaknesses in the signal processing code implementing the physical and link layers of the OSI stack. Our test bed includes multiple nodes leveraging both GNU Radio and the Universal Software Radio Peripheral to demonstrate these attacks and corresponding defensive strategies. More specifically, we examine two duplex modem implementations,...
Research in recent years have led to the emergence of technologies for remote monitoring of patients with the wireless transmitted to biomedical signal obtained from various sensors. Specialist person who monitors can be connected via a router to the IP address of the wireless board monitoring system, and through software developed in LabVIEW graphical programming software can read the value of measuring...
In Wireless Local Area Networks (WLANs), providing seamless mobility and balancing load among Access Points (APs) are challenging issues due to simple signal strength based association and hand-off mechanisms employed at wireless clients. Extensions to Software Defined Networking (SDN) framework for wireless networks could help to address theses issues in an efficient and cost-effective manner with...
To show a computer screen on a large display, so far, wired cable connections like VGA, HDMI, and DisplayPort are mainly used. Recently, wireless display technology is becoming popular, especially on mobile devices like PCs, tablets, and smartphones. “Tap to Display” is a connection method triggered by an NFC tap operation. It enables users to show the desktop screen of his PC on the destination Miracast...
This paper describes implementation of ECG Sensor. The system is capable of acquiring and storing patient's ECG data in real-time. This received patient data can be further processed for any real time processing applications. System hardware comprises of micro-controller based ECG acquisition system. Software developed in Visual Basic 6 helps in displaying real time ECG signal. It also stores ECG...
This paper describes a multi-purpose display and a timer developed for athletics. Traditional displays can be used for only one item of athletics, but this display can be used at long jump, throwing events, and combined events. In addition, these devices have the features of wireless communication, low cost, and easiness for users to handle. These have been already on sale and used at athletic games,...
