Emerging 5G networks will not only offer higher link rates, but also integrate a variety of Radio Access Technologies (RATs) in order to provide ultra-reliable broadband access to a wide range of applications with high throughput and low latency requirements. SDN-enabled dynamic path selection is of critical importance in exploiting the collective transmission resources in such heterogeneous multi-RAT...
Network providers now want to enable users to define their own flow priorities, and commercial devices already implement this ability. However, it has been shown that directly applying arbitrary user-defined priorities can fundamentally destabilize a network. In this paper, we show that it is possible to apply user-defined priorities while keeping the network stable. We introduce U-BP, a scalable...
The Dynamic Adaptive Streaming over HTTP (DASH) is specified to cope with the changing network conditions and provide an adaptive bit-rate HTTP-based streaming solution. While there have been many researches of rate adaptation algorithms on adaptive HTTP streaming, much of the work is focused on Video on Demand (VoD) service — which is not same as live streaming. It is generally preferred to minimize...
Data center energy consumption has become one of the top concerns in designing and operating large-scale data centers as cloud service providers such as Amazon, Google, IBM and Microsoft have begun to establish more data centers in response to growing requests in clouds. In recent years, extensive efforts have been put into the research of reducing the energy consumption of servers. With the improvement...
The current local area networks (LANs) are occupied by a large variety of heterogeneous consumer devices, equipped with the ability to connect to the Internet using a variety of different network technologies (e.g., Ethernet, 2.4 and 5GHz Wi-Fi). Nevertheless, devices generally opt to statically connect using a single technology, based on predefined priorities. This static behaviour does not allow...
Backpressure-based adaptive routing algorithms have been studied extensively in the literature. Although backpressure-based adaptive routing algorithms have been shown to be network-wide throughput optimal, they typically have poor delay performance under light or moderate loads because packets may be sent over unnecessarily long routes. Further, backpressure-based algorithms have required every node...
We investigate the problem of joint AP coverage adjustment and user association optimization for load balancing in multi-rate WLANs in this paper. We first divide the problem into two sub-problems and then formulate them as mixed integer linear programming models, which aim to minimize the AP utilization of the most congested AP while satisfying users' traffic demands. Then we design two corresponding...
The paper presents the results of design explorations for the implementation of the Smith-Waterman (S-W) algorithm executing DNA and protein sequences alignment. Both design explorations studies and the corresponding FPGA implementations are obtained by writing a dynamic dataflow program implementing the algorithm and by direct high-level synthesis (HLS) to FPGA HDL. The main feature of the obtained...
Network life time is a critical aspect of application in wireless sensor networks (WSN). Furthermore energy consumption and security has arisen as a major aspect in network design. In this article, a study of the backoff exponent (BE) management in the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) method under the Medium Access Control (MAC) is conducted. While BE parameter define...
The problem of cooperative spectrum leasing among multiple primary users (PUs) and secondary users (SUs) is considered. A hybrid Stackelberg-coalition formation game theoretic algorithm is proposed that enables the PUs to identify a group of cooperative SUs by looking at the reputation history of their cooperative behavior. The coalition formation approach also promotes collaboration among the SUs...
Simultaneous Multithreading (SMT) increases processor throughput by allowing the parallel execution of several threads. However, fully sharing processor resources may cause resource monopolization by a single thread or other misallocations, resulting in overall performance degradation. Static resource partitioning techniques have been suggested, but are not as effective as dynamically controlling...
Software has gained its importance in all aspects of every walk of life. Algorithms play a vital role in ensuring the successful operation of any software. According to the applications, various algorithms have been designed in order to accomplish the desired goals. This paper therefore aims to provide an insight on significance of performance and further, throw light on various matrix multiplication...
This paper studies the application of fixed-parameter tractable (FPT) algorithms to solve computer-aided design (CAD) problems. Specifically, we focus on layout decomposition problems for three lithography technologies: double patterning lithography (DPL), DPL with E-beam lithography (DPL+EBL), and DPL+DSA+EBL. Layout decomposition for the first two technologies are long-standing open problems without...
Adaptive video streaming is today's predominating video delivery model in the Internet. However, existing bitrate adaptation achieves satisfactory performance only under buffering of several tens of seconds. The major challenge is the stabilization of client buffer dynamics, because a small buffer lacks resilience to the buffer fluctuation imposed by the mismatch between the network throughput and...
Today, Cloud Computing provides many technological oriented applications distributed over the internet. Cloud Computing facilitate tremendous changes in the IT world, to increases the maximum profits from this new platform. In IT industry everyday new applications coming up and increases the complexity of scheduling process. For this purpose, job scheduling plays a most important responsibility in...
In indoor scenarios, visible light communication (VLC) access point (AP) can provide very high throughput and meet any illumination demands, while wireless fidelity (Wi-Fi) provides basic coverage in a large range. In this paper, the downlink resource allocation (RA) problem for hybrid VLC and Wi-Fi network is considered. A resource allocation algorithm combined with optical power dynamic allocation...
Emerging Information-Centric Networking (ICN) architectures seek to optimally utilize both bandwidth and storage for efficient content distribution over the network. The Virtual Interest Packet (VIP) framework has been proposed to enable joint design of forwarding, caching, and congestion control strategies within the Named Data Networking (NDN) architecture. While the existing VIP algorithms exhibit...
This paper studies a wireless network consisting of multiple transmitter-receiver pairs sharing the same spectrum where interference is regarded as noise. Previously, the throughput region of such a network was characterized for either one time slot or an infinite time horizon. This work aims to close the gap by investigating the throughput region for transmissions over a finite time horizon. We derive...
In this paper, we consider a renewable energy powered wireless relay node which can work in either full- duplex (FD) or half-duplex (HD) mode. It decodes and stores data bits sent from source node, and then transfers them to destination node. We aim to maximize the average throughput from source to destination by optimizing the relay's working mode under the random energy arrival constraint. Optimal...
In this paper, we propose a novel distributed deadline-based routing and spectrum allocation algorithm for tactical ad-hoc networks. The proposed algorithm will enable nodes to adapt to various deadline requirements unique to each traffic classes. A tactical ad-hoc network needs to handle a variety of data flowing through the network including voice, surveillance video, threat alert among others....
