Abstract
With the increase of usage of wireless networks for purposes where the nodes are either stationary or minimally mobile, focus is also on increasing the network capacity of wireless networks. One such way is to use non-overlapping multiple channels provided by 802.11 by using multiple interfaces per node. Multiple nonoverlapped channels exist in the 2.4GHz and 5GHz spectrum. However, most IEEE 802.11-based multihop ad hoc networks today use only a single channel. As a result, these networks rarely can fully exploit the aggrega ....etc

Data Acquisition and Data Logging



What is data acquisition and data logging
Data acquisition is simply the “gathering of information about a system or process”
Information may be gathered for various reasons
knowledge
research and development
systems or process monitoring
systems or process control
Data acquisition requires one or more transducers (sensors) to sense the system or process, and a signal measuring instrument

Abstract
In this paper, an effort has been made todesign and developed a 4-channel data logger for indoorenvironment. Initially the present work hasconcentrated to environmental parameter (temperatureand humidity) and more polluted contaminants(concentration level of CO and CO2). The Data logger isproposed to be developed with the use ofmicrocontroller PIC 18F4458 (inbuilt 8 channel ADC),i.e. 4 channels will be used and 4 channel will open inexternal sensor. Real Time Clock is also interfaced forsampled data with the instance of sampli ....etc

Abstract
Two major factors that limit the throughput inmulti-hop wireless networks are the unreliability of wirelesstransmissions and co-channel interference. One promising techniquethat combats lossy wireless transmissions is opportunisticrouting (OR). OR involves multiple forwarding candidates torelay packets by taking advantage of the broadcast nature andspacial diversity of the wireless medium. Furthermore, recentadvances in multi-radio multi-channel transmission technologyallows more concurrent transmissions in the network, and sh ....etc

Multichannel Data Acquisition Systems



Precision Analog Applications Seminar

Multiplexing allows one ADC to do the work of several in a multichannel system. Rather than dedicating an ADC to each channel, a single converter can read every channel in sequence. This can save power, since ADCs can use a significant amount of power while switches use very little, and it can save cost, since switches are much cheaper than ADCs.

Moments and Channel Capacity of Single and
Dual-Branch Receivers Over Weibull Fading Channels



ABSTRACT

Diversity combining receivers is the well-known technique used to combat fad-
ing and improve system performance. There are several diversity reception methods
employed in digital communication receivers including maximal-ratio combining, se-
lection combining and switched diversity. Among the combining methods, switched
diversity offers one of the least complexity solution for fading mitigation and ....etc
