Research ArticleOpen accessIn the abstractPERFORMANCE ANALYSIS OF ADHOC ON DEMAND DISTANCE VECTOR PROTOCOL WITH BLACKHOLE ATTACK IN WSNMuhammad Ibrahim Channa, Kamalrulnizam Abu Bakar, Adnan AhmedThe security is major challenging issue in wireless sensor network applications because they are operated in public and unrestrained areas which also makes difficult to protect against tampering or captured by an adversary force that can launch insider attacks to make a node compromised. One type of such attack is black hole attack. Existing AODV routing protocol does not have … …Journal of Computer Science, Vol. 10, Issue 8 · 26 Feb 2014 · 7,588 accessesView PDFCite
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 abstractTHE ERROR REGISTRATION TECHNIQUE FOR MANEUVERING RADAR NETWORKLiu Yu, Wang Haipeng, Xiong Wei, He YouThis study studies are error registration algorithm for the maneuvering radar network, which is one of the difficult problems of multi-sensor registration. When the maneuvering radar has no orientation bias, measurement equations of both attitude bias and measurement bias can be established by using the common targets observed by different radars. Based on the equations, the real-time estimation of both … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 6,581 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Robust Recognition System for Pecan Weevil using Artificial Neural NetworksSaleh Mufleh Al-SaqerProblem statement: Pecan Weevil is a widely found pest among pecan trees and these pests are known to cause significant damage to the pecan trees resulting in enormous annual losses to pecan growers. Traditional identification techniques for pecan weevil include traps with pheromones to detect the infestation of these pests. However, these traditional methods require expensive labor hours to set-up … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 14 Jul 2012 · 6,831 accessesView PDFCite
Research ArticleOpen accessIn the abstractRealization of Fault Tolerant Routing Protocol for ZigbeeSharmila Sankar, SankaranarayananProblem statement: Increased use of handheld devices and sensor devices pose problems in existing routing protocols. The performance of the existing routing protocols deteriorates very much on these dense scenarios. Control overheads are very important parameter in deciding the performance of routing protocols, which are introduced during route discovery and maintenance process. Denser the network, higher is the control overhead … …Journal of Computer Science, Vol. 8, Issue 5 · 2 Mar 2012 · 6,827 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Performance Evaluation of Routing Algorithms in IEEE 802.15.4 and IEEE 802.11 with Different Ad Hoc Routing ProtocolP. Anitha, C. ChandrasekarProblem statement: Wireless ADHOC networks are self organized dynamic networks can share wireless channel without any established central control standard for IEEE 802.11. Approach: The most common protocols are AODV, DSDV, DSR in ADHOC used to ensure the data transmission among themselves. To meet the need of low power and low cost IEEE 802.15.4 standard was developed for sensor networks. … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,409 accessesView PDFCite
