A rogue access point is a wireless access point that has either been installed on a secure company network without explicit authorization from a local network administrator or has been created to allow a hacker to conduct a man-in-themiddle attack. In this paper, we propose two online algorithms to detect rogue access points using sequential hypothesis tests applied to packet-header data collec...

We consider the N -user broadcast erasure channel where feedback from the users is fed back to the transmitter in the form of ACK messages. We first provide a generic outer bound to the capacity of this system; we then propose a coding algorithm, compute its throughput region and show that it achieves capacity under certain conditions on channel statistics, assuming that instantaneous feedback ...

The end-to-end TCP congestion control based on a window flow control mechanism can cause unfairness among multiple TCP connections with different RTT (round trip time), dut to its non-uniform increase of the rate. In order to achieve the fairness among TCP connections, we propose a rate control scheme using ECN (Explicit Congestion Notification) on TCP congestion control. At an ECN-implemented ...

Lysine acetylation is a major posttranslational modification involved in a broad array of physiological functions. Here, we provide an organ-wide map of lysine acetylation sites from 16 rat tissues analyzed by high-resolution tandem mass spectrometry. We quantify 15,474 modification sites on 4,541 proteins and provide the data set as a web-based database. We demonstrate that lysine acetylation ...

A DFT-SOFM-RBFNN method is proposed to improve the accuracy of DFT calculations on Y-NO (Y = C, N, O, S) homolysis bond dissociation energies (BDE) by combining density functional theory (DFT) and artificial intelligence/machine learning methods, which consist of self-organizing feature mapping neural networks (SOFMNN) and radial basis function neural networks (RBFNN). A descriptor refinement s...

In recent years, Vehicular Ad Hoc Networks (VANETs) experience growing interest in both academia and industry. VANETs apply multiple channels, namely Control Channel (CCH) and Service Channels (SCHs), to provide road safety services and improve the comfort and efficiency of driving. Based on the time slotted p-persistent channel access mechanism, this paper proposes a multiple priority supporte...

New broadband access technologies such as Hybrid Fiber Coaxial (HFC) are likely to provide fast and cost effective support to a variety of applications including Video on demand (VoD), interactive computer games, and internet-type applications such as Web browsing, ftp, email, and telephony. Since most of these applications, use TCP as the transport layer protocol, the key to their success larg...

TCP Westwood (TCPW) is a TCP protocol relying on a continuous estimation of the packet rate of a connection. Based on the ACK reception rate, a sender computes the congestion window and slow start threshold settings after a congestion period in the network. Given that, TCP throughput greatly depends on how fast and accurate these estimates are made. In this paper, we study TCPW ABSE bandwidth e...
