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 A comparative study of packet combining based error recovery schemes for wireless networks انتشار 2014
Int. J. Ad Hoc and Ubiquitous Computing, Vol. 16, No. 3, 2014 Sheng-Shih Wang*, Pei-Chun Lee, Kan-Yen Linand Tzu-Chang Yeh Abstract: To provide reliable communications in wireless environments, two fundamental errorcontrol mechanisms, automatic repeat request (ARQ) and forward error correction (FEC) areproposed. However, the ARQ mechanism may suffer frequent retransmissions and the FECmechanism incurs bandwidth overhead. To reduce the number of retransmissions and supportefficient correction, pr ...دانلود مقاله A packet error recovery scheme for vertical handovers mobility management protocols
