In this paper, the antenna location in distributed antenna system with hybrid user distribution is discussed. Instead of maximizing the cell ergodic rate, we focus on minimizing the expectation of squared distance applying selective transmission schemes. Using the weighted expectation of squared distance criterion (WESDC), the optimization problem of antenna location is proved to be convex when two...
In this paper, success on cellular nonlinear network emulator core that generates active waves such as autowaves and traveling waves is intended. This wave computer core has 4 × 4 parallel processing units. Cellular nonlinear network in this study has 16, 384 nodes arranged in 128 × 128 normal grid form. The evolution algorithm of the network is executed by the hardware implemented on a Xilinx XC2VP30-FF896...
Hadoop YARN is an open project developed by the Apache Software Foundation to provide a resource management framework for large scale parallel data processing. However, there exists a resource waiting deadlock under the Fair scheduler when the resource requisition of applications is beyond the amount that the cluster can provide. In such a case, the YARN system will be halted if all resources are...
Still lacking a standard architecture, cloud computing requires sophisticated ways to estimate resources for the requesting cloud service customers (CSCs). CSC show random behavior in utilizing various services. In this regard, if all the CSCs are treated in the same way, not only cloud service providers (CSPs) suffer because of uctuating utilization behavior of CSCs, but also CSCs suffer, since they...
The growing demand for the monitoring of patients, and the potential promise of cloud computing has allowed considering a number of cloud-based systems and services for health care. The cloud computing, in combination with the popularity of smart handheld devices has inspired healthcare professionals to remotely monitor patients' health while the patient is at home. To this end, this paper proposes...
The multi-armed bandit (MAB) problem has been an active area of research since the early 1930s. The majority of the literature restricts attention to i.i.d. or Markov reward processes. In this paper, the finite-parameter MAB problem with time-dependent reward processes is investigated. An upper confidence bound (UCB) based index policy, where the index is computed based on the maximum-likelihood estimate...
The inadequate resource allocation, lack of I/O performance prediction and insufficient isolation are affecting the storage performance in the multi-tenant cloud storage environment. In order to guarantee the Quality of Service (QoS), Softwaredefined Storage (SDS) is an effective approach in data centers. However, the lack of intelligence, robustness and selfadjustment are blocking the applications...
Over the decades people have seen a change from large mainframe computing to commodity, off-the-shelf clusters of high performance computers. Currently data centers have thousands or tens of thousands of high performance computers that provides services as well as computation for tens or hundreds of thousands of users. Traditional IT challenges such as scheduling, resource allocation and now data...
Use of Internet in today's world has been largely dominated by content dissemination but currently used IP architecture is based on connection between hosts. In order to disseminate content efficiently in cost effective manner, internet architecture needs to map "what" user wants with "where" host of network is. Content Centric Networking (CCN) decouples content from host. CCN...
Equipping classrooms with inexpensive sensors can provide students and teachers with the opportunity to interact with the classroom in a smart way. In this paper an approach to acquiring contextual data from a classroom environment, using inexpensive sensors, is presented. We present our approach to formalising the usage data. Further we demonstrate how the data was used to model specific room usage...
Grid computing is considered as the upcoming phase of distributed computing. Grid focuses on maximizing the resource utilization of an organization by sharing them across application. Ingrid computing, job scheduling is an important task. Load balancing and resource allocation are vital issues that must be considered in a grid computing environment. Load balancing is the technique which distributes...
Peer-to-Peer Network consisting of nodes with limited power that are deployed to gather useful information from the field. In P2P it is critical to collect the information in an efficient manner, sometimes Single point failure can be occurred, and also congestion can be occurred in the network. In order to avoid those problems we proposed a new technique called Bio-Inspired mechanism for caching....
A mortal finding out proteins logs into a pc and uses a complete network of computers to investigate knowledge. A man of affairs accesses his company's network through a personal organizer so as to forecast the long run of a selected stock. a military official accesses and coordinates pc resources on 3 completely different military networks to formulate a battle strategy. All of those situations have...
Grid computing creates the illusion of a simple but large and powerful self-managing virtual computer out of a large collection of connected heterogeneous systems sharing various combinations of resources which leads to the problem of load balance. In this paper, two techniques such as MMS and EMS are proposed for job scheduling in grid. The objective of the scheduling process is to map each job with...
Cloud computing provides attractive solutions for dispatching services over the Internet. With the increase of more and more Internet users, the job of allocating the resources by the cloud providers has become a challenging task. In this paper, a new technique called Drip Based Resource Allocation (DBRA) is proposed for allocating cloud resources or Physical Machines (PMs) to the incoming jobs using...
That paper focus on how to select cloud service provider (CSP) for the user which provide the best service to the user. Selection of the proper CSP depends on the rating of CSP. If rating of CSP is higher than that CSP would be select for the first user and so on. Paper has focused on both rating of CSP and rating of particular attribute of CSP. In this Paper selection of CSP depends on both rating...
Content Caching is a promising solution that can reduce network traffic, lower latency and improve the performance in 5G cellular networks. Video content is one of the most important types of multimedia traversing the cellular networks. It generates more traffic on network than any other types of multimedia. Hyper Text Transfer Protocol (HTTP) is one of the widely used protocols for content delivery...
Grid environment has significant challenges due to failures encountered during job execution. Grid infrastructure must have mechanisms to deal with faults while also providing efficient and reliable services to its end users. Therefore fault tolerance in such an environment could not be ignored. In this paper, two strategies such as Maximum Mapping Strategy (MMS) and Exact Mapping Strategy (EMS) are...
To make the allocation of hardware resources more reasonable and flexible on private infrastructure as a service cloud platform in enterprises, approving system described in this paper provides an efficient solution. Each user has a basic quota. If users need to get more resources, the reason must be given to apply. According to the performance of the eventually practice on OpenStack, this system...
Allowing cellular operators to offload data traffic to unlicensed spectrum has the potential to significantly increase the capacity of the cellular network systems. This paper considers the spectrum sharing among multiple cellular operators in the unlicensed spectrum. One of the main challenges for this system is how to control the interference between the cellular users and the unlicensed users in...
