We introduce a framework for optimal resource allocation in smart grids. We consider two components of the smart grid; the power distribution network and the data communication network. By defining suitable utility functions, the power and bandwidth resources are optimally allocated. This requires the solution of the, so called, local public goods problem, in mathematical economics terminology. We...
IEEE 802.16 standard provides a revolutionary air interface that enables very high data rates over large distances. It incorporates a Quality of Service (QoS) framework to ensure satisfactory transmission of different classes of traffic. However, the actual implementation of QoS mechanisms is not defined in the standard and left out for service providers. One of the five different classes of services...
As real-time multi-player games are increasingly popular network applications nowadays and 802.11 wireless are widely used, it is common that games are played over 802.11 networks. However, game performance can be degraded when competing with background traffic. In this paper, we propose Application Divided Resource Allocation (ADRA) scheme based on 802.11e to support games in a mixed traffic 802...
This work studies the power control algorithm proposed by Foschini-Miljanic (1993), standardized for universal mobile telecommunication systems (UMTS). Continuous and discrete time versions of this algorithm are analyzed. First, it is shown that the distributed power allocation scheme can be visualized as a tracking problem of an equivalent power reference that specifies the desired quality-of-service...
For resource coordination and management of large construction machinery in engineering projects, the revised dual node network was used to program the distribution and use of large machinery, and to design the distribution process of network planning. On the basis of rational multitasking allocation with network planning method, the target procedure was tracked and controlled to reach the goal of...
We present an explicit adaptive traffic allocation scheme for optimum distribution in heterogeneous networks, where data traffic is broken down into multiple sub-flows, such that the aggregate of these multiple sub-flows at the terminal are merged into the original flow. For simplicity, parallel data transmission through inter-network cooperation is modeled as a sequent M/M/1 queue system. We aim...
CoMP (Coordinated Multiple Point transmission) is being discussed in 3GPP (3rd Generation Partnership Project) to improve the cell edge performance as well as the total cell throughput of mobile systems. In this paper, we focus on the control architecture to realize downlink CoMP JT (joint transmission) with inter eNB (evolved NodeB) coordination. We have designed the control architecture with a distributed...
Joint detection in the uplink of a cellular network involving several non-colocated base stations is a promising means to turn inter-cell interference into useful signal energy and hence dramatically increase spectral efficiency of reuse one networks. To maximize the benefits of the new degrees of freedom that come with base station cooperation, cluster centric schedulers need to be aware of the interference...
Given that statistical multiplexing of video streams is employed in enhanced Multimedia Broadcast/Multicast Service (e-MBMS), we address the issue of scheduling across the streams towards Advanced-Long Term Evolution (LTE-A) system, in order to improve the quality of service (QoS) performances. In this paper, the optimization problem of scheduling and resource allocation for separate streams is first...
Long Term Evolution (LTE) is a promising technology for 4G mobile networks. Due to utilize OFDMA in downlink and SC-FDMA in uplink, the LTE system is expected to provide significantly high throughput with 20 MHz spectrum allocation. To increase the cell throughput and multi-user diversity gain, channel dependent scheduling (CDS) is implemented for the OFDMA-based multi-user scenario to allocate resource...
With the fast improvement in technology, we are now moving toward exascale computing. Many experts predict that exascale computers will have millions of nodes, billions of threads of execution, hundreds of petabytes of inner memory and exabytes of persistent storage. For systems of such a scale, frequent failures are becoming a serious concern. One of the most important reasons is that in a large-scale...
This work proposes an adaptive intercell interference avoidance scheme for the self-organization in Orthogonal Frequency Division Multiple Access (OFDMA) femtocell networks. Due to the expected large number of user-deployed cells, the femtocell networks suffers from the intercell interference problem. In this paper, we define the self-organizing resource allocation problem to maximize resource efficiency...
In this paper we propose an inter-cell coordination scheme that coordinates the transmission time and mode of users in neighboring cells. The scheme is designed for 3G LTE systems and therefore takes into account interface constraints especially for the uplink. The objective of the scheme is to assign physical resource blocks together with the transmission mode to users in a way that minimizes interference...
The aviation community is currently working on the standardization of data communication systems for the future air traffic management. In this context, the International Civil Aviation Organization (ICAO) has initiated a work on standardization of an IPv6-based aeronautical telecommunications network and on future radio access technologies, respectively. In this paper, we integrate L-Band Digital...
We study a problem of optimal resource allocation in cooperative communication network with finite state fading channels and queueing. The control problem is to assign resources dynamically within the cloud of mobile users subject to the longterm average power constraint in order to stabilize the queues and maximize the long-term average throughput of the system. By modeling the problem as a finite...
Effective exploitation of the application-specific parallel patterns and computation operations through their direct implementation in hardware is the base for construction of high-quality application-specific (re-)configurable application specific instruction set processors (ASIPs) and hardware accelerators for modern highly-demanding applications. Although it receives a lot of attention from the...
This paper presents a scalable asynchronous distributed control network. The control circuit allows for true asynchronous operation of all digital resources and as a result of its scalable distributed topology allows unlimited resource sharing. We start with the description of a data flow graph, and using traditional scheduling algorithms, generate an asynchronous distributed control network and the...
We propose a method of distributed team formation that uses reinforcement learning and dynamic reorganization by taking into account communication delay in multi-agent systems (MAS). A task in a distributed environment is usually achieved by doing a number of subtasks that require different functions and resources. These subtasks have to be processed cooperatively in the appropriate team of agents...
This paper analyzes workload characteristics and power usage of parallel high-performance computing system. According to the conclusions of the analysis, we propose two kinds of power-aware scheduling policies to reduce the power consumption of system by power down idle nodes reasoningly. Detailed experiments using data from the Parallel Workloads Archive indicates that both policies can achieve considerable...
