Interference Avoidance in Rapidly Deployed Wireless Ad hoc Incident Area Networks

Interference Avoidance in Rapidly Deployed Wireless Ad hoc Incident Area Networks

A common strategy for responding to indoor emergency scenarios is to rapidly deploy a group of first responders inside the incident area and an incident command center outside of the incident area. First responders are equipped with radios that allow them

Second Preimage Attacks on Dithered Hash Functions

Second Preimage Attacks on Dithered Hash Functions

We develop a new generic long-message second preimage attack, based on combining the techniques in the second preimage attacks of Dean Dean99} and Kelsey and Schneier KS05} with the herding attack of Kelsey and Kohno KK06}. We show that these generic

On Maximizing Provider Revenue in Market-based Compute Grids

Market-based compute grids encompass service providers offering limited resources to potential users with varying demands and willingness to pay. Providers face difficult decisions about which jobs to admit and when to schedule admitted jobs. For this

Spatial Interpolation Algorithm for Error Concealment

Spatial Interpolation Algorithm for Error Concealment

In this paper, we propose a new spatial interpolation algorithm for Intra-Frame error concealment. The method aims at interpolating areas in the image, which have been affected by packet loss. We have proposed an edge detection technique to aid the

Clustering Characteristics of Millimeter Wave Indoor Channels

Clustering Characteristics of Millimeter Wave Indoor Channels

Temporal-Angular channel sounding measurements of an indoor millimeter wave channel (60 GHz) is analyzed to determine whether ray arrivals at the receiver form clusters in the two-dimensional time-angle space. The channel behavior for directional antennas

Predictive Link Trigger Mechanism for Seamless Handovers in Heterogeneous Wireless Networks

Predictive Link Trigger Mechanism for Seamless Handovers in Heterogeneous Wireless Networks

Effective and timely link-layer trigger mechanisms can significantly influence the handover performance. The handover process will not perform the correct decision and execution unless adequate and timely link-layer trigger information is delivered. In

Quantize-and-Forward Relaying with M-ary Phase Shift Keying

Quantize-and-Forward Relaying with M-ary Phase Shift Keying

Using cooperative transmission, two or more single-antenna users can share their antennas to achieve spatial diversity in a slow fading channel. One relaying protocol that achieves diversity, amplify-and-forward (AF), is striking in its simplicity, but

The CLEAR 2007 Evaluation

This paper is a summary of the 2007 CLEAR Evaluation on the Classification of Events, Activities, and Relationships which took place in early 2007 and culminated with a two-day workshop held in May 2007. CLEAR is an international effort to evaluate systems

A Two-Tier Bloom Filter to Achieve Faster Membership Testing

A Two-Tier Bloom Filter to Achieve Faster Membership Testing

Testing for element membership in a Bloom Filter requires hashing of a test element (e.g., a string) and multiple look-ups in memory. A design of a new two-tier Bloom filter with on-chip hash functions and cache is described. For elements with a heavy

A quantitative study of the practical sensitivity limit of a terahertz absorption spectrometer.

A quantitative study of the practical sensitivity limit of a terahertz absorption spectrometer.

In gas spectroscopy, chemicals can be identified by the set of frequencies at which their absorption lines occur. The concentration can be quantitatively estimated from the intensity of any of the absorption lines. The sensitivity of the spectrometer, i.e

On Test Collections for Adaptive Information Retrieval

Traditional Cranfield test collections represent an abstraction of a retrieval task that Sparck Jones calls the core competency of retrieval: a task that is necessary, but not sufficient, for user retrieval tasks. The abstraction facilitates research by

Absorption, transmission, and scattering of expanded polystyrene at millimeter-wave and terahertz frequencies

Conventional material measurements of transmission and reflection in the millimeter-wave and terahertz frequency range do not differentiate between scattering and absorption, grouping effects from both mechanisms together into 'loss'. Accurate knowledge of
