دانلود مقاله Forward Error Correction in Sensor Networks

Jaein Jeong and Cheng Tien EeDepartment of Electrical Engineering and Computer ScienceUniversity of California, BerkeleyMay 16, 2003 AbstractIn any network, there are two basic methods to recover errorneous packets. One way is to useAutomatic Repeat Request (ARQ), and another is Forward Error Correction (FEC). Since, in sen-sor networks, power is scarce and is primarily consumed by wireless transmission and reception,we would prefer to use FEC rather than ARQ. In this paper we determine empirica ...

دانلود مقاله Error Correction Codes in Wireless Sensor Network: An Energy Aware approach انتشار 2010

World Academy of Science, Engineering and TechnologyVol:4 2010-01-26 Mohammad Rakibul Islam   Abstract—Link reliability and transmitted power are two importantdesign constraints in wireless network design. Error control coding(ECC) is a classic approach used to increase link reliability andto lower the required transmitted power. It provides coding gain,resulting in transmitter energy savings at the cost of added decoderpower consumption. But the choice of ECC is very critical in thec ...

دانلود مقاله AN ANALYSIS OF VARIOUS PARAMETERS IN WIRELESS SENSOR NETWORKS USING ADAPTIVE FEC TECHNIQUE

M.R.Ebenezar jebarani1and T.Jayanthy2   ABSTRACTIn Wireless sensor network, since the media is wireless there will be burst errors which leads tohigh bit error rate that affect the throughput. Wireless sensor networks drop the packets due to propagationerrors that lead to retransmission traffic. This paper evaluates the effect of adaptive FEC in Wirelesssensor networks. Adaptive FEC technique improves the throughput by dynamically tuning FEC dependingupon the wireless channel loss. The main ...

دانلود مقاله A multipath routing protocol for wireless sensor network for mine security monitoring - انتشار 2010

Mining Science and Technology (China) Volume 20, Issue 1, January 2010, Pages 148–151   XIAO Shuo1,2,*, WEI Xueye2, WANG Yu2   Abstract: Underground mining is a hazardous industrial activity. In order to provide a safe working environment for miners, aWireless Sensor Network (WSN) technology has been used for security monitoring. It can provide a wide range of surveillancewith a relatively low cost. In this study, an Energy-Based Multipath Routing (EBMR) protocol is proposed, wh ...
