A mechanism to improve the throughput of cloud computing environments using congestion control-

Abstract :
Cloud computing as a new model for the delivery of applications, platforms or computing resources, including processing, memory, bandwidth, etc. to customers in return for the used payment method emerged. Therefore it has become important to share cloud resources, so as to provide them economically. In cloud computing services, multiple types of resources, such as processing ability, bandwidth and storage, need to be allocated simultaneously. If there is a surge of requests, a competition will arise between these requests for the use of cloud resources. This leads to the disruption of the service and it is necessary to consider a measure to avoid or relieve congestion of cloud computing environments. The basic issue here is to provide a new congestion control method for cloud computing environments which reduces the size of required resource for congested resource types instead of restricting all service requests as in Conventional methods. In this research, congestion control implemented in allocation level of available resources in the datacenters to virtual machines And we evaluated its impact on the cloudlets response time and throughput of cloud computing environments by comobining it with a new cloudlets allocation strategy. In order to simulate the proposed mechanism named CCMICC, CloudSim3.0.3 software has been used. It is demonstrated by simulation evaluations that CCMICC can allocate more resources to virtual machines compared with the conventional methods and relieve the congestion. the proposed method can improve the throughput of cloud computing environments as well as service quality.

Abstract

A level of trust can be developed by online relationships in social network which are based on real world relationships. To form a dynamic Social Cloud and to enable users to share heterogeneous resources within the context of a social network we have proposed leveraging of the social relationships. We believe that combining trust relationships with suitable incentive mechanisms could provide much more sustainable resource sharing mechanisms. We have introduced a business application as a means of regulating sharing, due to the unique nature of the Social Cloud. The business application is innovative as it uses both social and economic protocols. In today's world, social community credentials are being used for authentication purpose on various other websites (e.g. Facebook). Here we outline our vision of creating a Social Storage Cloud, looking especially at po

چکیده

یک سطح اطمینان بین دو نهاد را می‌توان با استفاده از روابط آنلاین در شبکه‌ی اجتماعی-که مبتنی بر روابط واقعی می‌باشد- توسعه داد. به‌منظور ایجاد یک رایانش اجتماعی پویا و توانمندسازی کاربران به‌منظور به اشتراک‌گذاری منابع همگن در بافت شبکه‌ی اجتماعی، روشی را که متکی به روابط اجتماعی می‌باشد پیشنهاد می‌کنیم. اعتقادداریم که ترکیب روابط اطمینان با مکانیسم‌های تشویقی می‌تواند مکانیسم‌های به اشتراک‌گذاری منبع مناسب‌تری را فراهم سازد. یک اپلیکیشن تجاری را به‌عنوان ابزاری برای تنظیم اشتراک‌گذاری ارائه داده‌ایم که دلیل این انتخاب را ماهیت انحصاری کلود اجتماعی میدانیم. این اپلیکیشن تجاری، اپلیکیشنی نوآور می‌باشد چراکه از هر دو پروتکل اقتصادی و اجتماعی بهره می‌برد. در دنیای امروزی، از گواهی‌های یک جامعه‌ی اجتماعی به‌منظور هویت سنجی در وب‌سایت‌های مختلف دیگر (مانند فیس بوک) استفاده می‌شود. در اینجا، دیدگاه خود را بر روی ایجاد یک فضای ذخیره‌سازی اجتماعی معطوف می‌سازیم و به دنبال مکانیسم‌های بازار ممکنی می‌باشیم که می‌تواند به‌منظور ایجاد یک زیر ساختار ابری پویا در یک محیط شبکه‌ی اجتماعی بکار گرفته شود.

Abstract: Based on mobile nature in MANET, there is no doubt that all routing protocols have some route errors. Usually, routing protocols try to recover a route after a route error has been happened on an exact route to destination. This kind of route recovery could make more packet loss and also more time waste. This project adds Triangular Fuzzy Numbers to prediction of route errors and make route recovery as parallel of packet sending. Indeed, any node in this project uses a route error counter and an error prediction based on Fuzzy algorithm to recover its routes before an exact route error on its route discovery has been happened. There is no doubt that using suggested prediction cannot solve all route errors; but it could help routing protocols to improve their route recovery algorithm.This project uses DSR as one of the standard MANET routing protocols to simulate the results.

چکیــــده:

Most structural engineering optimization problems that are used in practice require considering the design variables as discrete quantities. This paper presents a modified honey bee mating optimization (MHBMO) algorithm for optimizing the truss structures with discrete design variables, which are subjected to stress, displacement and buckling constraint. In order to demonstrate the effectiveness of the mentioned algorithm, some numerical examples from the literature were tested using this method and their results were compared with those obtained using other well-known meta-heuristic search techniques. The results express that the MHBMO algorithm is very effective and robust for the discrete optimization designs of truss structural problems.
