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 ...دانلود مقاله Performance of a Hybrid ARQ Scheme in CDMA Wireless Sensor Network - انتشار 2011

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 ...دانلود مقاله Empirical evaluation of a cloud computing information security governance framework انتشار 2015

Journal of Network and Computer Applications Volume 47, January 2015, Pages 47–60 Muhammad Shiraz*, Mehdi Sookhak, Abdullah Gani, Syed Adeel Ali Shah AbstractDespite of substantial technological advancements in the recent years, Smart Mobile Devices (SMDs) are still low potential computingdevices. Therefore, Mobile Cloud Computing (MCC) deploys computational offloading for augmenting SMDs. The contemporary ComputationalOffloading Frameworks (COFs) implement resources intensive procedures ...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 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 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 ...Dictionary of Islamic Architecture (مجموعه شماره 1 کتب حکمت اسلامی)
