Research ArticleOpen accessIn the abstractPERFORMANCE COMPARISON OF HUFFMAN AND LEMPEL-ZIV WELCH DATA COMPRESSION FOR WIRELESS SENSOR NODE APPLICATIONAsral Bahari Jambek, Nor Alina KhairiWireless Sensor Networks (WSNs) are becoming important in today’s technology in helping monitoring our surrounding environment. However, wireless sensor nodes are powered by limited energy supply. To extend the lifetime of the device, energy consumption must be reduced. Data transmission is known to consume the largest amount of energy in a sensor node. Thus, one method to reduce the energy … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 10 Dec 2013 · 7,942 accessesView PDFCite
Research ArticleOpen accessIn the abstractA NOVEL HYBRID NODE LOCALIZATION ALGORITHM FOR WIRELESS SENSOR NETWORKSLiu Yu, Wang Haipeng, He You, Shen JianNode self-localization is one of the supporting technologies in Wireless Sensor Networks (WSNs). In this study, a distributed hybrid localization algorithm based on divide-and-conquer and refinement method is proposed. Firstly, the effect of ranging error in the Received Signal Strength (RSS) model on node localization is analyzed and the topology relations of anchors and unknown nodes are derived when the … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 6,878 accessesView PDFCite
