Novel cloud computing technology makes multiplayer cloud gaming a reality, where players play games that do not run on local devices, but on servers in the cloud. Nevertheless, the necessary communication between player's local device and cloud server increases the response delay of the gaming session. Besides the degrade of responsiveness, the inter-player delay, which is the difference of response...
Combined with the Moon exploration, it builds the simulation scenario about the communication between Deep Station and Moon Detector. It analyzes the problems in the deep communication, such as: the big path loss, large delay and intermittent communication. Based on the analysis, it provides the methods to solve the problems and analyzes the effect for using the appropriate measures which can enhance...
Experimentally is investigational influence of operating mode and steepness of pulse wavefront of anodic voltage on the magnitude of auxiliary thermionic cathode current of necessary for the start of magnetron with a secondary-emission cathode. It is shown that the size of this current increases with the increase of anodic voltage and steepness of pulse front.
In this paper, we consider a downlink coordinated multi-cells multi-users network, in which each User Equipment (UE) knows its Channel State Information (CSI) perfectly and feeds back its quantized composite channel to the distributed Base stations (BSs) through a limited feedback. We propose a cooperative beamforming design, considering quantized composite channels, that reduces the inter-cell interference...
Network virtualization has become one of the most prominent solutions that can efficiently deal with the dramatic increase of data demand in mobile networks. In order to allow multiple virtual networks to coexist in the same substrate network, the need for development of efficient virtual network embedding algorithms and techniques is imperative. The main purpose of this paper is to provide an optimization...
A mobile adhoc network is an independent system of mobile stations associated by wireless link to form a system. This system can be modeled in the form of an uninformed graph. Adhoc networks are peer to peer, multihope networks were data packets are transmitted to a source to destination through intermediate nodes (which serve as router). The infrastructure is not the main issue to setup MANET and...
Wireless networks are required to guarantee the Quality of Service (QoS), including throughput, fairness, delay, etc. IEEE802.11 MAC protocol employs a typical backoff mechanism, Binary Exponential Backoff (BEB) algorithm, to avoid collisions when multiple users try to access the shared wireless channel. Many works on QoS guaranteeing point out that the BEB algorithm introduces the unfairness and...
Approximate or inexact computing has recently attracted considerable attention due to its potential advantages with respect to high performance and low power consumption. This paper presents the design of an approximate multiplier; this approximate multiplier consists of an approximate Booth encoder, an approximate 4-2 compressor and an approximate tree structure. The approximate design is implemented...
For a priori undetermined nonlinear multi-mode dynamic object with several statement delays and the relative order greater than one, it offers a combined adaptive control system, synthesized using the hyperstability criterion and L-dissipativity conditions.
The main goal of this paper is to study the controllability of positive discrete linear time-varying fractional system with constant delay in control. The general formula of solution of difference state equation is used to formulate the necessary and sufficient condition for controllability of the considered system in a given time interval with respect to h-steps delay in control.
In this paper, we propose a general delay and stability performance analysis in Heterogeneous Cellular Caching Networks (HCCNs), based on queuing theory. We introduce new performance metrics in HCCNs and propose an optimization problem which minimizes the average experienced delay for users by ensuring the stability of the network. In addition, from the design perspective, we address the problem of...
Multipath TCP is an extension to TCP protocol that allows a single connection to be split across multiple paths. MPTCP overcomes few limitations of TCP thereby offering added benefits like increased throughput and network resource utilization and resilience to possible link failures. Different data paths over the network face different end-to-end path delay. The performance of MPTCP is affected not...
Now a days, low power Very Large Scale Integration (VLSI) circuit plays an important role in designing efficient energy saving electronic systems for high speed performance. In VLSI, low power dissipation is the main criterion in many electronic devices out of speed, area, etc., like mobile phones, laptops, high speed work stations etc., Due to the integration of many components on the VLSI circuit...
Mostly real time applications want rapid data transmission in the network. The performance can be ensured by mechanisms which gives performance by shaping and policing of packet traffic. Further improve the performance of the network by fair allocation of resources. Many congestion control techniques provide good fairness and throughput, which decreases the loss of packet. We have analyzed the strength...
Instant messenger, often shortened to IM is one type of communication service that allows person to have a conversation (chat) privately with others via the internet. Within the calls & messaging on Android and iOS operating systems, they both have an equal value in the terms of innovation and performance. In this work, we focus on evaluate the performance of the IM application on Android and...
In mobile communication, User Equipment (UE) always demands to be on the network and to perform different errands using applications like file transfer, video streaming and conferencing and other applications like messaging, etc. It needs higher bit rate and hence, UE in recent networks like 4G heterogeneous wireless network continuously use vertical and horizontal handover. For better Quality of...
This paper presents architecture for a fused floating point three term adder unit. The fused or merge technique is described in this paper because in a fused technique three term addition is done in single unit. The purpose of doing this is to reduce delay, area as compared to traditional addition method. Several optimization techniques are used to reduce delay. The proposed design is implemented...
With the increasing complexity of electronic circuits and to meet the demand of high performance, the design and optimization of electronic circuits need to be automated with high degree of reliability and accuracy. In order to optimize hardware requirements of digital combinational circuits, evolutionary and innovative techniques need to be enforced at various levels such as at gate level and device...
The performance of the Internet is dominated by that of the TCP which in turn depends that of its congestion control algorithm. The primary purpose of the TCP is to take care of the congestion collapse of Internet and also to act as resource optimization mechanism in best effort environment. However, this makes TCP to be unfriendly with real time applications for which UDP is preferred. There is no...
Scaling of integrated circuits leads to increase in design complexity of the transistors. Interconnect delay, Power dissipation and electromagnetic interferences arises due to increase in resistance and capacitance at the nanometer level. Sub threshold operation of devices for ultra-low power requirement necessitates the design issues of interconnects. Carbon nanotube (CNT) interconnects are the better...
