    The purpose of this paper is to describe a new emerging science: Internet science. This paper argues that current Internet is a direct by-product of Shannon's Information theory and its master thesis. After that I attempt a general and generic definition of a network and discuss the different alternatives. This discussion results in defining a network as a set of distributed actors cooperating for... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (853 KB) | HTML iconHTML

    Reducing fluctuations and mitigating the variability of wind energy is essential for its integration in grids, electricity markets, microgrids, and distributed generation settings. In this work, we present a storage-based wind power smoothing system that uses novel optimization algorithms to reduce the variability of wind energy. The system considers forecasted and actual energy generated, battery... View full abstract»

  • Multi-queued network processors for packets with heterogeneous processing requirements

    Modern network processors (NPs) increasingly deal with packets with heterogeneous processing requirements. In this work, we consider the fundamental problem of managing a bounded size buffer at the input queue of an NP. Incoming traffic consists of packets, each packet requiring several rounds of processing before it can be transmitted out of the queue. The objective is to maximize the total numbe...

    Data centers are used to host computation-intensive distributed applications. Since all the applications are distributed in nature, their performance is significantly affected by the communication network. These applications generally create two kinds of flows: large data flows that require high throughput and small control flows that require low delay. These two contradictory requirements are not...

    Scalable network wide flow monitoring has remained a distant dream because of the strain it puts on network router resources. Recent proposals have advocated the use of coordinated sampling or host based flow monitoring to enable a scalable network wide monitoring service. As most hosts in data centers get virtualized with the emergence of the cloud, the hypervisor on a virtualized host adds anoth... View full abstract»

    Twitter, with its rising popularity as a micro-blogging website, has inevitably attracted the attention of spammers. Spammers use myriad of techniques to evade security mechanisms and post spam messages, which are either unwelcome advertisements for the victim or lure victims in to clicking malicious URLs embedded in spam tweets. In this paper, we propose several novel features capable of distingu... View full abstract»

  • Residual White Space Distribution based opportunistic multichannel access protocol for dynamic spectrum access networks

    We propose a multichannel MAC protocol for cognitive radio enabled Secondary Users (SUs) called Residual White Space Distribution based Cognitive MAC protocol (RWS-CMAC). Channel access in RWS-CMAC is based on residual idle time distribution of the channels. RWS-CMAC assumes a common control channel, which is used by sender and receiver SU nodes to exchange control messages for data channel negoti... View full abstract»

    Quality of Service (QoS) based scheduling in Cognitive radio networks (CRN) is a pressing research problem. The objective of this work is to study the feasibility of using CRN for delay sensitive applications in the presence of primary users with random ON/OFF periods. The first contribution of this work is the modeling of a cognitive node as a Queuing system and characterization of the average de... View full abstract»

  • RODMAC: A RObust and Distributed MAC protocol for efficient use of white spaces

    Publication Year: 2013, Page(s):1 - 10
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (413 KB) | HTML iconHTML

    We describe the design, implementation and evaluation of a RObust and Distributed MAC (RODMAC) protocol for cognitive radio networks which exploit spectrum white spaces for communication. RODMAC incorporates two novel features. These are a robust design resilient to node failure and a scheme for on-demand channel hopping. Other features include a fully distributed architecture and incorporation of... View full abstract»

    This paper considers optimal resource allocation in integrated framework of cognitive radio and ad hoc network. The design problem looks for an optimal solution in power and channel allocation in multihop cognitive radio network (CRN) with linear topology. The overall goal is to minimize outage probability and enhancement in network lifetime, while meeting the limits of total transmit power and in... View full abstract»

  • SC-FDMA for multiuser communication on the downlink

    Single-carrier frequency division multiple access (SC-FDMA) has become a popular alternative to orthogonal frequency division multiple access (OFDMA) in multiuser communication on the uplink. This is mainly due to the low peak-to-average power ratio (PAPR) of SC-FDMA compared to that of OFDMA. Long-term evolution (LTE) uses SC-FDMA on the uplink to exploit this PAPR advantage to reduce transmit po... View full abstract»
