دانلود مقاله From Rateless to Distanceless: Enabling Sparse Sensor Network Deployment in Large Areas
Wan Du, Zhenjiang Li, Jansen Christian Liando, Mo Li AbstractThis paper presents a distanceless networking approachfor wireless sensor networks sparsely deployed in large areas.By leveraging rateless codes, we provide distancelesstransmission to expand the communication range of sensormotes and fully exploit network diversity. We addressa variety of practical challenges to accommodate ratelesscoding on resource-constrained sensor motes and devise acommunication protocol to efficiently coordinate ...دانلود مقاله Cross-Layer Analysis of Error Control in Wireless Sensor Networks
Mehmet C. Vuran Ian F. Akyildiz Abstract—Severe energy constraints and hence the low powercommunication requirements amplify the significance of theenergy efficient and preferably cross-layer error control mechanismsin Wireless Sensor Networks (WSN). In this paper, a crosslayermethodology for the analysis of error control schemes inWSNs is presented such that the effects of multi-hop routing andthe broadcast nature of the wireless channel are investigated.More specifically, the cross-layer ...دانلود مقاله Datalink Streaming in Wireless Sensor Networks
Raghu K. Ganti, Praveen Jayachandran ∗,Haiyun Luo, and Tarek F. Abdelzaher AbstractDatalink layer framing in wireless sensor networks usuallyfaces a trade-off between large frame sizes for highchannel bandwidth utilization and small frame sizes for effectiveerror recovery. Given the high error rates of intermotecommunications, TinyOS opts in favor of small framesizes at the cost of extremely low channel bandwidth utilization.In this paper, we describe Seda: a streaming datalinklaye ...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
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 ...
