In this paper, the authors define solid privacy requirements regarding privacy-maintain routing in MANET. Then, they propose a secure routing scheme to offer complete unlink ability and content un-observability for all types of packets. It is efficient as it uses a novel combination of group signature and ID-based encryption for route discovery. Security analysis demonstrates ...
Due to the limited resources of the network transmission of large sized data can be a bottleneck in ad hoc network. The data delivery is done by selecting appropriate cluster heads. This kind of region diversity may be utilized to achieve higher energy efficiency. The authors divide the network into four regions. Node with highest ...
In this paper, the driver circuits are proposed for Light Emitting-Diode (LED) lamps with a dimming feature. The two different drivers used are flyback converter and forward converter in series with the DC-link. In this paper, the two driver circuits are compared for the controlled output current and voltage. The dimming is achieved by pulse ...
The authors present an algorithm for order reduction of linear dynamic SISO discrete systems using the combined advantages of the improved generalized Least squares method and error minimization by Differential Evolution technique (DE). The denominator of the reduced order model is obtained by improved generalize least squares method and the numerator coefficients are determined by ...
The Omni wheeled robot consists of three Omni-wheels which are mounted at 120 degrees apart. These three wheels mounted on DC motors which will be driven by relay motor drivers that are Omni-directional motion of the robot possible with utmost ease. This robot is controlled by using mobile phone which has DTMF (Dual Tone Multiple ...
With continuing worldwide popularity, smart devices such as phones, pads, watches and glassed has become more sophisticated. Increasing strong demand for smaller insulated transformers, an ultra-small transformer has been developed by adopting an insulated hybrid structure with the size of W16.5 x L19.5 x H10.5 mm 3, whose volume is 65% smaller than conventional insulated ...
The WSN is a specialized wireless network made up of a large number of sensors and at least one base station. The foremost difference between the WSN and the traditional wireless networks is that sensors are extremely sensitive to energy consumption. Energy saving is the crucial issue in designing the wireless sensor networks. Since the ...
To configure a transceiver card for the hand held radio which is used for the transmission and reception of data or signals in war field. An RF agile transceiver IC is an IC which is programmable is used. The IC is programmed to transmit and receive the signals in war field. The hand held radio ...
Wireless mobile communication now demands large data bandwidth to accommodate various multimedia services. such a system requires a very high speed wireless transmission technique. a wireless channel environment is more subject to noise than a wired channel because the signals are open to external disturbances such as path loss, shadowing, and fading therefore, channel coding ...
In this paper, the authors focus on designing and controlling an articulated 3-DOF robotic arm using LabVIEW and NImyRIO. Now-a-days, robots have been used in common places of manufacturing and making the tasks ranging complicated and expensive to be automated, since technology formulates LabVIEW is used to make the robot more precise and practical along ...
