Design of Middleware and Software Embedded Development Kit For Area Based Distributed Mobile Cache System

Nowadays a new area-based distributed mobile cache system and a sustainable distributed Geo-cast technology enables data caching temporarily in a designated local area using short-range communication technologies such as Bluetooth and Wi-Fi. This system doesn’t need servers and infrastructure network. To enhance the short-range communications as a time-offset communication in a physical world the caching capability is needed. Due to this advantage it is sure to adopt a new location-based communication services. The proposed work is frames a developed middleware for a widespread embedded OS and a software development kit with an open application programming interface. The proposed middleware is expected to prompt the third-party developers to produce various applications using this platform and provided with some pseudo-code. And also explained the methods for using this platform by an implemented geo-location social game.

Cascading of Two Rectangular Waveguides by Using HFSS, Cascade and MATLAB Software

This project studies the analysis of cascading of two rectangular waveguide of different cross-Section It also shows how to combine all the scattering matrices of a microwave circuit to obtain its overall scattering parameters of the circuit .Simulation of cascading of two rectangular waveguide with different dimensions by using HFSS and computer program in MATLAB is developed to calculate the S parameter of cascaded two rectangular waveguide. Finally above these two results are compared with the results obtained from the CASCADE. CASCADE is a highly efficient and accurate tool for designing 2-port waveguide components, RF windows, and waveguide systems. The program is very user-friendly and executes very rapidly on standard personal computers.

Performance Enhancement of Spectral efficiency and throughput with Distributed Dynamic channel allocation using genetic algorithm

The efficiency associated with mobile systems will depend on a good channel allocation method. Some sort of genetic algorithm (GA) dependant on distributed dynamic channel allocation model is offered. Mobile service stations (MSS) help to make every one of the channel allocation decision intended for mobile hosts in that cell based on the local information. Proposed model which reuses available channels more efficiently. A reserved pool associated with channels in each and every cell to make the model fault tolerant which allows any mobile or portable to continue communication with its mobile hosts within the absence of adequate channel within the cell. Therefore, the offered GA intended for distributed dynamic channel allocation to reinforce the spectral efficiency along with throughput of the cell network. Simulation results evaluate the performance of the distributed dynamic channel allocation based on genetic algorithm.

A Line Utilization Factor and Krill Herd Algorithm based Optimal Utilization of Interline Power Flow Controller for Congestion Management

In order to increase transmission line stability, control power flow and improve the security of transmission systems FACTS technology has been extensively employed. And these devices must be optimally placed in the transmission systems for their best usage. In this paper to control the congestion in the transmission lines we use DLUF (Disparity Line Utilization Factor) for the appropriate placement of IPFC. The difference between the percentages MVA utilization of each line connected to the same bus is determined by the DLUF. The IPFC is placed in the lines with maximum DLUF. Krill Herd Algorithm has been used for optimal tuning of IPFC for a multi objective function. The multi objective function comprises of minimization of active power loss, security margin, voltage deviation and capacity of installed IPFC. The effectiveness of proposed method is tested for IEEE–30 bus test system.

Comparative Analysis of Low Power and Low Leakage Reduction for Logic Circuits

As technology scales in nanometer regime leakage current are becoming important metric of comparable importance to leakage current for the analysis and design of complex logic circuits. In this paper, we did the comparative analysis of leakage current for carry look ahead logic circuits. The simulation results depicts that the proposed design leads to efficient in terms of standby leakage power. We have performed simulations using Cadence Spectre 90nm standard CMOS technology at room temperature with supply voltage of 1V.
