Research ArticleOpen accessIn the abstractCoverage Eligibility Rule based Coverage Maintenance Protocol for Energy Conservation in Wireless Sensor NetworksA. Balamurugan, T. PurushothamanProblem statement: Wireless Sensor Networks (WSNs) comprise of small nodes with sensing, computation and wireless communication capabilities. Nodes in a sensor network are severely constrained by energy and computing power. Continuous working of sensor nodes leads to quick depletion of battery power and reduces the overall lifetime. To prolong the lifetime of the sensor nodes, efficient routing protocol that could … …Journal of Computer Science, Vol. 7, Issue 10 · 6 Aug 2011 · 6,630 accessesView PDFCite
Research ArticleOpen accessIn the abstractAuthenticated Broadcast in Heterogeneous Wireless Sensor Networks using Chinese Remainder Theorem AlgorithmKalyani Palanisamy, ChellappanProblem statement: The security in Wireless Sensor Networks (WSN) is a critical issue due to the inherent limitations of computational capacity, storage capacity and power usage. Key management only makes sure the communicating nodes possess the necessary keys, at the same time protecting the confidentiality, integrity and authenticity of the communicated data. Approach: Proposed a RSA-CRT methodology for authenticated broadcast … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractVLSI Implementation of Novel Class of High Speed Pipelined Digital Signal Processing Filter for Wireless ReceiversRozita Teymourzadeh, Yazan Samir Algnabi, Masuri Othman et al.Problem statement: The need for high performance transceiver with high Signal to Noise Ratio (SNR) has driven the communication system to utilize latest technique identified as over sampling systems. It was the most economical modulator and decimation in communication system. It has been proven to increase the SNR and is used in many high performance systems such as in the … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 7,815 accessesView PDFCite
Research ArticleOpen accessIn the abstractLink Stability and Node Energy Conscious Local Route-Repair Scheme for Mobile Ad Hoc NetworksAnuradha Banerjee, Paramartha DuttaProblem statement: A mobile ad hoc network is a self-configuring network of mobile nodes connected by wireless links. As the nodes are free to move randomly, topology of the network may change rapidly and unpredictably. As a result, intermediate nodes in the communication routes tend to lose connection with each other during the communication process. In order to repair a … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 6,856 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow Power Phase Locked Loop Frequency Synthesizer for 2.4 GHz Band ZigbeeNesreen Mahmoud Hammam Ismail, Masuri OthmanProblem statement: Wireless communication systems are required for many applications. There are different standards for these systems. IEEE 802.15.4 defines the communication system standard for zigbee. This study discussed designing one of the blocks of zigbee transceiver which is the Phase Locked Loop (PLL). A major target for any communication systems is saving battery power, especially for zigbee as it … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,057 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Power Control with Overhearing Avoidance for Wireless Sensor NetworksM. Ramakrishnan, P. Vanaja RanjanProblem statement: Extending lifetime of the battery operated wireless sensor nodes through the design of low power medium access control protocols dealt in this study. Approach: In this study energy efficient Optimal Power Control MAC with Overhearing Avoidance (OPC-OA) was proposed. The transmission power of every node was dynamically changed for the optimal connectivity between nodes. The optimal transmission power … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,131 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Studies on the Performance of Low Power Transmitters for Wireless Sensor NodesT. Sasilatha, J. RajaProblem statement: Power consumption was one of the most challenging aspects to design low power wireless sensor nodes. The objectives of the study were to (i) Design low voltage, low power transmitters for wireless sensor nodes and (ii) Compare and analyze the performance of the transmitters. Approach: The transmitters employed direct digital modulation scheme to reduce the power consumption of … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,450 accessesView PDFCite
Research ArticleOpen accessIn the abstractRandom Graph Generation Based p-Method and Box Method for the Evaluation of Power-Aware Routing Protocols of Ad hoc NetworksSaleh H. Al-SharaehThe objective of this paper is to investigate the best solution such that on which decision should be made to forward a wireless packet. The decision should be made in such a way to keep the node alive by choosing an alternate path, through those nodes that have more power reserve. Minimizing the consumption of the reserve power will results … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Saving Mechanism in Clustered Ad-Hoc NetworksArwa Zabian, Ahmed IbrahimIn wireless Ad-Hoc networks, multihop transmission breaks the single hop path from a mobile node to another, into two or more hops, in a manner that the distances between transmitter and receiver are smaller than that in the direct transmission, which reduces the transmission power significantly. We have proposed the use of graph search algorithms to increase the power remaining … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 7,117 accessesView PDFCite
Research ArticleOpen accessIn the abstractTopology Discovering and Power saving Mechanism for Routing in a Tree of Ad-hoc Wireless NetworksArwa ZabianPower management in mobile network is an open challenges where the power level in the network influences the network life time.
