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

ABSTRACT
The problem of tracking multiple objects moving through a network of wireless sensors is studied. It is assumed that each sensor has a limited range for detecting the presence of the object, and that the network is sufficiently dense so that the sensors cover the area of interest. In order to conserve energy the sensors may be put into a sleep mode with a timer that determines the sleep duration. It is assumed th ....etc

Multi-sensor Data Fusion in Automotive Applications

ABSTRACT
The application of environment sensor systems in modern – often called “intelligent” – cars is regarded as a promising instrument for increasing road traffic safety. Based on a context perception enabled by well-known technologies such as radar, laser or video, these cars are able to detec ....etc

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

Abstract
It seems to many of us these days that the pace of technological change is so great that it outstrips our imaginations — just as soon as we can conceive of the next nifty electronic gadget we'd like to have, we find out that somebody has already built it.
Miniaturized devices such as cameras and telephones are examples of now-common technologies that just a few years ago most of us rarely encountered outside the fictional world of spy ....etc

MULTI SENSOR IMPLEMENTATION SYSTEM


In embedded system we have often come across the system employing different types of sensors built using single technology.

Here in this multi sensor implementation system we want to expose ourselves to the way a sensor built and how to use them for different applications. we have chosen simple and cost effective IR technology for this purpose.

System consists of three photos sensors arranged as reflective sensor, slot sensors and single photo diode. Microcontroller AT89S52 is used to take inputs fr ....etc
