Abstract—

This paper is an extended work of Hasan et al., (2012) where a teletraffic model was shown. In a previous research work, the authors presented a k fold multicast network with optimum output. Multicast has brought a change in network operation by providing bandwidth effective technology and reducing traffic loads. It is popular for performance optimization in a network. In this paper, a new model has been designed to establish a suitable value of the fold k of a k-fold multicast network under different traffic loads under Poisson traffic with finite queue at each node. Stationary distribution has been derived for the network states with the derivation of expressions for the network throughput and the blocking probability of the network. The research has explored that the network throughput increases very fast if the fold number is increased. However, at a certain value of the fold, the blocking probability stops to increase and it becomes constant. The study further discovered that as the offered traffic is increased, the throughput also increases. With the increase of system parameter k, the blocking probability decreases. Moreover, after an optimum value of k, the blocking probability becomes static for a particular value of the offered traffic.

here Abstract:

This paper is intended for verifying the implementation of Long Term Evolution (LTE) over satellite in Forward Link. Recent developments in wireless communication such as MIMO technique that allow improving the received signal quality and capacity, in combination with OFDM makes the signals more robust against delay spread in frequency selective channel. A dual satellite Orthogonal Frequency Division Multiplexing and Multiple-Input and Multiple-Output (OFDM-MIMO) model is considered which provides a handy and robust resource over satellite channel for this purpose. It is OFDM in aggregation to quadrature phase shift keying (QPSK) with Turbo Coding using 2×2 MIMO as specified for LTE 5 MHz BW, transmitted with satellite power delay profile has analyzed in terms of Bit Error Rate (BER). Spatial multiplexing and diversity are the two features that MIMO provides which has also been investigated. The investigation has been conducted considering downlink transmission over satellite forward link over dual-satellite 2×2 MIMO channel.

Nowadays social media games such as games in facebook platform is one of the fastest growing and popular industries in the world. The goal of most social games is to entertain the player through the interaction among the players and the non-player characters (NPCs) within their friends or mutual friends. Thus, it is required to develop suitable NPCs that are fun to play against and the area of computational intelligence offers us a variety of techniques to do so. Since its beginning, game playing was a field of research in Artificial Intelligence (Al). In games, Artificial Intelligence (Al) is used to produce the illusion of intelligence in the behavior of NPCs. In the Pac-Man game, the NPCs are the ghosts. This paper illustrates a research design of MS. Pac-Man game by implementing neural networks in the movements of ghosts. Each ghost is given an unique intelligent method for movement to establish the levels of challenges in the Pac-Man game and making the game more interesting and fun to play. In addition, performance of the apps and Application Programming Interface (API) have been examined in facebook platform to check its compatibility and user friendliness.

Abstract:

Multicast network is widely used for effective communication, transmission and performance optimizations of a network. In this paper, a new model has been developed to determine a suitable value of the fold k of a k-fold multicast network under different traffic loads under Poisson traffic with finite queue at each node. We have derived stationary distribution for the network states and then derived expressions for the network throughput and the blocking probability of the network. It has been found in this research work that the network throughput increases very fast as we increase the fold number. However, at a certain value of the fold, the blocking probability ceases to increase and it remains constant. We have also observed that as the offered traffic is increased, the throughput also increases. Moreover, the system parameter k is increased, the blocking probability decreases. However, after an optimum value of k, the blocking probability remains constant for a particular value of the offered traffic. In fact, in this paper, by evaluating the performance of a k-fold multicast network, our developed model improves the performance of a multicast network.

Multicast network is widely used for effective communication, transmission and performance optimizations of a network. In this paper, a new model has been developed to determine a suitable value of the fold k of a k-fold multicast network under different traffic loads under Poisson traffic with finite queue at each node. We have derived stationary distribution for the network states and then derived expressions for the network throughput and the blocking probability of the network. It has been found in this research work that the network throughput increases very fast as we increase the fold number. However, at a certain value of the fold, the blocking probability ceases to increase and it remains constant. We have also observed that as the offered traffic is increased, the throughput also increases. Moreover, the system parameter k is increased, the blocking probability decreases. However, after an optimum value of k, the blocking probability remains constant for a particular value of the offered traffic. In fact, in this paper, by evaluating the performance of a k-fold multicast network, our developed model improves the performance of a multicast network.

follow url Abstract—

Cloud Computing has become an emerging field of research in recent days for its various cost effective approaches. In this research work, we have developed a live chatting system based on cloud computing to demonstrate its effectiveness in call centers. The developed system follows the core idea of cloud computing, especially the ‘Software as a Service’ (SaaS) model and its utilization in IT solution companies. The demand of this model is increasing rapidly among the clients because of its cost efficiency and flexibility. Moreover, customer care service providing companies spend a lot of money to buy and maintain chatting software. For this reason, a real time chatting application has been developed in this work in such a way that users of this system can have on-demand and hosted services. The application has been created by using Dot Net framework and written in C# with Asynchronous JavaScript and XML (AJAX) and Language- Integrated Query (LINQ) functionalities. The application has been designed as a web based real time software to those companies, which are worried about expenses and maintenance of the customer care software. The system was simulated in a real time environment to support and solve customers’ queries. This cloud based application also guarantees how one can be benefitted using the SaaS model compare to the existing system.

By the end of this decade we will be entering into the era of thousand cores SoCs. 3D integration technologies have opened the door of new opportunities for NoC architecture design in SoCs providing higher efficiency compared to 2D integration by appropriately adjusting the increased path lengths of 2D NoC. The application to core mapping on NoC architecture can significantly affect the amount of system’s dynamic communication energy consumption. The considerable amount of energy savings can be achieved by appropriately optimizing the application to core mapping in NoC architecture. This paper presents a Branch-and-Bound heuristic for smart application to core mapping in 3D Mesh NoC architecture.
