دانلود مقاله An Error-Aware Routing Protocol over Lossy Links in Wireless Sensor Networks

Liankuan Zhanga, Deqin Xiaob, Procedia Engineering 29 (2012) 1492 – 1500 Available online at www.sciencedirect.com  SciVerse ScienceDirect AbstractAs Bit errors fluctuate wildly in different environments and they fluctuate steadily for a givenpair of sensor nodes, we propose an error-aware routing protocol (EARP). Compared to otherestimators, bit errors can directly reflect the wireless channel state and can be used in complexregions. In this paper, we use parameter VerValue to choose ...

دانلود مقاله An Approach towards Improving the Lifetime and Security in Wireless Sensor Network

Mayuri P. Kawalkar et al, / (IJCSIT) International Journal of Computer Science and Information Technologies, Vol. 5 (2) , 2014, 2604-2611 Mayuri P. Kawalkar1, Dr. S.A.Ladhake1 Abstract— A Wireless Sensor Network (WSN) is a collection ofwireless sensor nodes forming a temporary network withoutthe aid of any established infrastructure or centralizedadministration. In such an environment, due to the limitedrange of each node’s wireless transmissions, it may benecessary for one sensor no ...

دانلود مقاله An Improvement on Route Recovery by Using Triangular Fuzzy Numbers on Route Errors in MANET

IOSR Journal of Computer Engineering (IOSR-JCE)e-ISSN: 2278-0661, p- ISSN: 2278-8727Volume 16, Issue 1, Ver. II (Jan. 2014), PP 75-79 Sara Aliabadi¹, Mehdi Agha Sarram¹ Abstract: Based on mobile nature in MANET, there is no doubt that all routing protocols have some route errors. Usually, routing protocols try to recover a route after a route error has been happened on an exact route to destination. This kind of route recovery could make more packet loss and also more time waste. This ...

دانلود مقاله Amplify-and-Forward Compressed Sensing as an Energy-Efficient Solution in Wireless Sensor Networks- انتشار 2014

IEEE SENSORS JOURNAL, VOL. 14, NO. 5, MAY 2014 Joan Enric Barceló-Lladó, Antoni Morell, and Gonzalo Seco-Granados   Abstract—In this paper, we propose a novel distributed compressedsensing transmission scheme, which is referred to asamplify-and-forward compressed sensing (AF-CS), in order toimprove the existing tradeoff among reconstruction error, energyconsumption, and resource utilization. The goal is twofold. First,to take advantage of the time correlation in order to ...

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 ...
