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 ...ادامه مطلب ...

Ad Hoc Networks Volume 16, May 2014, Pages 131–141 Kyu-Hwan Lee, Sunghyun Cho, Jae-Hyun Kim AbstractWe evaluate the practical network coding (NC) gain in a wireless ad hoc networks.First, we introduce how network coding can be applied to IEEE 802.11ad hoc networks. Next, we find obstructive factors by which the NC gainmay decrease as compared with the theoretical NC gain. Finally, throughthe performance evaluation, we analyze why a performance difference occursbetween practical and ...ادامه مطلب ...

J Inf Process Syst, Vol.8, No.4, December 2012 R.Sumathi* and M.G.Srinivas** Abstract—With the increasing demand for real time applications in the Wireless SenorNetwork (WSN), real time critical events anticipate an efficient quality-of-service (QoS)based routing for data delivery from the network infrastructure. Designing such QoSbased routing protocol to meet the reliability and delay guarantee of critical events whilepreserving the energy efficiency is a challenging task. Considerable r ...ادامه مطلب ...

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 ...ادامه مطلب ...
