In this paper, we propose effective channel assignment algorithms for network utility maximization in a cellular network with underlaying device-to-device (D2D) communications. A major innovation is the consideration of partial channel state information (CSI), i.e., the base station (BS) is assumed to be able to acquire “partial” instantaneous CSI of the cellular and D2D links, as well as, the interference...
In this paper, we focus on a problem of joint subcarrier and rate allocation for an orthogonal frequency division multiple access (OFDMA) full-duplex (FD) system. The goal is to maximize the system's successful transmission rate (referred as goodput) subject to power constraints at the base station (BS) and uplink users alone with subcarrier constraints. Imperfect channel state information (CSI) at...
PT is a lightweight job scheduler based on client-server architecture with remote interfaces. PTServer, the server-side of PT, is designed as an open service running on the multiprocessor system to collaborate with any PTClient, the client-side of PT, on top of PTComer protocol. In PT, we call once execute of program as a task and several tasks formed into a job. The two functionality PT need to implement...
Nowadays, increasing importance has been attached to power management in modern data centers. A lot of solutions have been produced to reduce power consumption without producing an effect on quality of service. One common way is to associate with virtualization technology that has been widely used in data centers. This is due to not only its features of reliability and ease of management,but also...
Resource scheduling is a key process for clouds such as Infrastructure as a Service cloud. To make the most efficient use of the resources, we propose an optimized scheduling algorithm to achieve the optimization or sub-optimization for cloud scheduling problems. We investigate the possibility to place the Virtual Machines in a flexible way to improve the speed of finding the best allocation on the...
In this paper, we discuss resource management in modern wireless communications with the objective of minimizing power consumption, and carry out an analysis of simultaneous transmission and orthogonal transmission schemes in an FDMA (Frequency Division Multiple Access) framework. Based on a two-link line model with path-loss only, the performance of these two schemes for network power minimization...
Resource allocation in grid environment is a complex undertaking due to the heterogeneity and dynamic nature aroused by wide area sharing. To address the heterogeneous and computationally intractable problem of resource allocation optimization in grid, this paper presents an allocation algorithm for parallel tasks based on particle swarm optimization. The heterogeneity of grid user is tackled by introducing...
