In this paper, a continuous-time state space model approach is derived for congestion control in multiple hop communication networks. The model of single hop control is first proposed and then state feedback congestion control model of the entire network with multiple hops is suggested. A state space model equation is derived from the network model and linear quadratic regulator (LQR) as optima...

In this paper, we evaluate the performance of the photonic packet switch architecture to which packet scheduling algorithms is applied with fiber delay line buffers which function as the shared buffer. Since, in a shared buffer type switch, a void space introduces unacceptable performance degradation when high traffic load conditions, we propose a void space reduction method to resolve the prob...

With the advance of computing technology, video compression technology, and cellular network infrastructure, rich multimedia applications are dramatically boosted to users. Currently, a deterministic service model has been developed in which a QoS aware network assisted by the deterministic traffic modeling can provide bounded delay and loss free guarantees to video packets. However, the limite...

In this work we propose an adaptive buffer-aided space-time coding scheme for cooperative wireless networks. A maximum likelihood receiver and adjustable code vectors are considered subject to a power constraint with an amplify-andforward cooperation strategy. Each multiple-antenna relay is equipped with a buffer and is capable of storing the received symbols before forwarding them to the desti...

Virtual channels have been introduced to enhance the performance of wormhole-switched networks. They are formed by arranging the buffer space dedicated to a given physical channel into multiple parallel buffers that share the physical bandwidth on a demand driven time-multiplexed manner. The question to be answered is: given a fixed amount of finite buffer what is the optimal way to arrange it ...

Virtual channels have been introduced to enhance the performance of wormhole-switched networks. They are formed by arranging the buffer space dedicated to a given physical channel into multiple parallel buffers that share the physical bandwidth in a demand driven time-multiplexed manner. There have been few attempts to study the optimal arrangement of virtual channels (i.e. given a fixed amount...

Fluid queue driven by a birth and death process (BDP) with only one negative effective input rate has been considered in the literature. As an alternative, here we consider a fluid queue in which the input is characterized by a BDP with alternating positive and negative flow rates on a finite state space. Also, the BDP has two alternating arrival rates and two alternating service rates. Explici...

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

On-chip interconnection networks (OCINs) have emerged as a modular and scalable solution for wire delay constraints in deep submicron VLSI design. OCIN research has shown that the design of buffers in the router influences the energy consumption, area overhead, and overall performance of the network. In this paper, we propose a low-power low-area OCIN architecture by reducing the number of buff...

in the past 25 years, rising of the caspian sea level, part of a natural treat to the sea, has inundated and destroyed many buildings and arable lands and threatened many inhabitations in coastal areas. the main reason for these damages is that the law-setback has lost its efficiency and human activities have proceeded seaward. the goal of this study is to introduce a proper setback line for th...
