Research ArticleOpen accessIn the keywordsModified Power Save Model for Better Energy Efficiency and Reduced Packet LatencyNarendran Rajagopalan, C. MalaDevices constituting wireless ad-hoc networks generally operate in battery power, energy efficiency is a critical research issue. IEEE 802.11 Power Save Mode is a standard recommended for energy efficient operation of wireless ad-hoc networks. When there is no data to transfer, energy is still utilized by IEEE 802.11 PSM during the ATIM window. With this work, an attempt is made … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 3 · 29 Aug 2012 · 8,312 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSecure Authentication Technique for Data Aggregation in Wireless Sensor NetworksV. Bhoopathy, R. M.S. ParvathiProblem statement: In Wireless Sensor Networks (WSN), serious security threat is caused by node capture attacks where an adversary gains full control over a sensor node through direct physical access. Approach: This creates a high risk of data confidentiality. Results: We propose a secure authentication technique for data aggregation in WSN. During first round of data aggregation, the aggregator upon … …Journal of Computer Science, Vol. 8, Issue 2 · 24 Jan 2012 · 7,286 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHROUGHPUT ANALYSIS OF AGGREGATION WITH FRAGMENT RETRANSMISSION PLUS QUALITY OF SERVICE SCHEMETeuku Yuliar Arif, Riri Fitri SariAggregation with Fragment Retransmission (AFR) is a scheme designed for frame transmission to increase efficiency at the MAC layer throughput. AFR provides a higher throughput compare to Distributed Coordination Function (DCF) scheme. However AFR scheme did not has QoS service function when compared to DCF scheme. DCF scheme already has contention-based QoS service using Enhanced Distributed Coordination Function (EDCA) scheme. … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 7,319 accessesView PDFCite
