Mitigation of Control Channel Jamming under Node Capture Attacks



Abstract:

Availability of service in many wireless networks depends on the ability for network users to establish and maintain communication channels using control messages from base stations and other users. An adversary with knowledge of the underlying communication protocol can mount an efficient denial of service attack by jamming the communication channels used to exchange control messages. The use of spread spectrum techniques can deter an external adversa ....etc

Small-signal modelling of the transistor laser including the quantum capture
and escape lifetimes



The transistor laser was rst introduced in , and it was
predicted that this device could have a high-speed modula-
tion bandwidth of up to 100 GHz . In the transistor laser
(TL), a quantum well (QW) is embedded in the base of the
bipolar junction transistor (BJT) and acts as an optical col-
lector. The stimulated recombination causes compression in
the I- ....etc

Abstract—The technology of Radio Frequency IDentification (RFID) enables many applications that rely on passive, battery-less wireless devices. If a RFID reader needs to gather the ID from multiple tags in its range, then it needs to run an anticollision protocol. Due to errors on the wireless link, a single reader session, which contains one full execution of the anticollision protocol, may not be sufficient to retrieve the ID of all tags. This problem can be mitigated by running multiple, redundant reader sessions and use the statistical re ....etc

SCREEN CAPTURE AND MULTICAST

By
JEBIN A B




Abstract

This paper introduces a message forwarding algorithm for search applications within mobile ad hoc networks that is based on the concept of selecting the nearest node from a set of designated nodes.
The algorithm, which is called Minimum Distance Packet Forwarding (MDPF) uses routing information to select the node with the minimum distance.
The goal of the proposed algorithm is to minimize the average number of hops taken to rea ....etc

Abstract
The mobility of wearable computers makes usability testing difficult. In order to fully understand how a user interacts with the wearable, the researcher must examine both the userâ„¢s direct interactions with the computer, as well as the external context the user perceives during their interaction. We present a tool that augments a wearable computer with additional hardware and software to capture the information needed to perform a usability study in the field under realistic conditions. We examine the challenges in doing the ....etc

Optimal State Allocation for Multicast Communications with Explicit Multicast Forwarding- IEEE TRANSACTIONS ON PARALLEL AND DISTRIBUTED SYSTEMS, VOL. 19, NO. 4, - Java

Abstract—
In this paper, we propose a scalable and adaptive multicast forwarding mechanism based on Explicit Multicast (Xcast). This mechanism optimizes the allocation of forwarding states in routers and can be used to improve the scalability of traditional IP multicast and Source-Specific Multicast. Compared with previous work, our mechanism needs fewer routers in ....etc

Abstract
Approximately one third of all CO2 emissions due to human activity come from fossil fuels used for generating electricity, with each power plant capable of emitting several million tones of CO2 annually. A variety of other industrial processes also emit large amounts of CO2 from each plant, for example oil refineries, cement works, and iron and steel production. These emissions could be reduced substantially, without major changes to the basic process, by capturing and storing the CO2. Other sources of em ....etc
