[ 1 ] - Optimizing image steganography by combining the GA and ICA
In this study, a novel approach which uses combination of steganography and cryptography for hiding information into digital images as host media is proposed. In the process, secret data is first encrypted using the mono-alphabetic substitution cipher method and then the encrypted secret data is embedded inside an image using an algorithm which combines the random patterns based on Space Fillin...
[ 2 ] - ارائه روشی مبتنی بر نظریه مجموعه‌های فازی و الگوریتم جستجوی گرانشی برای بهبود الگوریتم زنبورعسل در شبکه‌های ویژه خودرویی
در این مقاله، با استفاده از نظریه مجموعه‌های فازی، الگوریتمی برای انتخاب سرخوشه و بهبود الگوریتم زنبورعسل به‌منظور مسیریابی در شبکه‌های ویژه خودرویی ارائه شده است. با توجه به اینکه تغییر سریع توپولوژی و ازدحام در شبکه‌های ویژه خودرویی باعث شکست اتصال‌ها می‌شوند، پروتکل پیشنهادی با بررسی میزان پایداری و ازدحام اتصال‌ها، میزان اعتبار هر گره و اتصال را محاسبه می‌کند. با توجه به اهمیت به دست آوردن ...
[ 3 ] - Hybrid multi-criteria group decision-making for supplier selection problem with interval-valued Intuitionistic fuzzy data
The main objectives of supply chain management are reducing the risk of supply chain and production cost, increase the income, improve the customer services, optimizing the achievement level, and business processes which would increase ability, competency, customer satisfaction, and profitability. Further, the process of selecting the appropriate supplier capable of providing buyerchr('39')s re...
[ 4 ] - Intuitionistic fuzzy logic for adaptive energy efficient routing in mobile ad-hoc networks
In recent years, mobile ad-hoc networks have been used widely due to advances in wireless technology. These networks are formed in any environment that is needed without a fixed infrastructure or centralized management. Mobile ad-hoc networks have some characteristics and advantages such as wireless medium access, multi-hop routing, low cost development, dynamic topology and etc. In these netwo...
