subjects of intense speculation by industry observers and potential users of the technologies , appear as if they may be ready to begin competing for their place in the networking sun. The demand for both technologies is being caused by the increasing adoption of Internet and intranet technology and the growing number of bandwidth-hungry applications. These factors make it necessary to move an ...

Understanding the end-to-end packet delay dynamics of the Internet is of crucial importance since it directly affects the QoS (Quality of Services) of realtime services, and it enables us to design an efficient congestion control mechanism. In this thesis, we measure the round-trip time in the actual operating Internet, and build a mathematical model representing its dynamics using system ident...

Wi-Fi applications have blossomed tremendously over the last few years. What started out as cable replacement for static desktops in indoor networks has been extended to fully mobile broadband applications involving wide-area outdoor community networks, moving vehicles, high-speed trains, and even airplanes. Wi-Fi data rates have also continued to increase from 2 to 54 Mbit/s with current 802.1...

T he rapidly increasing availability of high-performance networking is arguably com-puting's most significant contribution to society in the past 20 years. Despite network availability, it is difficult to evaluate how well high-performance applications use its complex, multilevel interconnections in the real world. To better understand this interaction, leading experts and organizations in ultr...

Any number that can be uniquely determined by a graph is called invariant. During the last twenty years’ countless mathematical invariants have been characterized and utilized for correlation analysis. However, no reliable examination has embraced to decide, how much these are related with network or molecular graph. In this paper, it will discuss three different variants of bridge networks goo...

ارتقای بازدارندگی دفاعی مستلزم تولید گسترده و متنوع محصولات تجهیزات نظامی است که نیازمند به‌کارگیری ظرفیت‌ها قابلیت‌های وسیع صنعتی است. ازآنجاکه تصدی تملک همه این قابلیت‌ها منطقی اقتصادی نیست، بخشی از فعالیت‌های تولیدی در صنایع دفاعی، برون‌سپاری می­‌شود به ایجاد شبکه بزرگی تأمین‌کنندگان منجر شده گستردگی شبکه، تعاملات همکارانه بهبود عملکرد زنجیره تأمین را یک چالش جدی برای مدیران تبدیل کرده سازما...
