Abstract: Cloud computing consists of a cluster of computing resources that are delivered over a network, which is accomplished by utilizing virtualization technologies to consolidate and allocate resources suitable for various different software applications. Therefore, an efficient task scheduling in the cloud would be required to improve the performance of the cloud. In this paper, implementation of a model that seeks to improve load balancing algorithm for virtual machine load balancing was performed using simulations. A method by which average burst time was used as the time quantum for the round robin load balancing algorithm to achieve more effective time sharing. Results obtained from the simulations along with performance evaluation carried out shows response time and data center processing time achieved using the improved model is slightly minimal compared to the other algorithms. This shows more effective load balancing by achieving a better overall throughput.

Abstract: A new compact Bandpass Microstrip filter with very wide band is presented using Reconfigurable Bandpass Microstrip Filter, it is reconfigured and simulated to Reconfigured Compact Bandpass Microstrip (RCBM) Filter to minimize the size of the filter and to enhance its bandwidth (BW). The achieved BW is 1.54GHz with minimum amount of insertion loss of -0.5dB and compactness of 1/3rd size reduction in the filter compared to its original filter size. In this methodology- varying the spacing, length and width of transmission lines of this RCBM is done. Hence by the variation of its dimensions the size of the filter is reduced with enhanced BW. These filters are used in handheld communication systems- here the size of each component, size of overall system and incorporating more number of features to that system is the main goal in recent research of handheld communication and these are the most important parameters. For this purpose compact filters are required, hence the proposed work is to achieve the compactness of the Microstrip Bandpass Filter by reconfiguring the compact Bandpass micro strip filter and increasing their performance. The proposed RCBM Filter is successfully realised in theory and verified by full wave electromagnetic simulation and the experiment. The simulated and measured results are in excellent agreement.
