Research ArticleOpen accessAll words, across the recordEnergy-Efficient Ant Colony-Based k-Hop Clustering and Transmission Range Assignment Protocol for Connectivity Construction in Dense Wireless Sensor NetworksGokou Hervé Fabrice Diédié, Boko Aka, Michel BabriConnectivity construction is the main phase of a communication-oriented topology control process. It consists of improving the current network physical topology while preserving important properties such as connectivity and symmetry. In this paper, we address the problem of combining two of the techniques commonly used for this purpose in networks composed of a large number of energy constrained wireless sensor-nodes … …Journal of Computer Science, Vol. 14, Issue 3 · 19 Mar 2018 · 7,792 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSFAD2H: Selective Forwarding or Dropping Attack Detection with 2-Hop Acknowledgment Support in Wireless Sensor NetworksPrathap Uppara, Kiran Krishnappa, Deepa Shenoy Punjalkatte, Venugopal Kuppanna RajukSecurity in wireless sensor networks is critical due to its way of open communication. In this study we have proposed a technique based on a sensor node having alternate path knowledge and 2-hop acknowledgement mechanism to detect adversary nodes which perform selective forwarding and dropping attacks. In selective forwarding attack nodes on the forwarding path refuses to transfer packets selectively. … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 23 Nov 2017 · 7,457 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Firefly-Inspired Scheme for Energy-Efficient Transmission Scheduling Using a Self-Organizing Method in a Wireless Sensor NetworksZeyad Ghaleb Al-Mekhlafi, Zurina Mohd Hanapi, Mohamed Othman, Zuriati Ahmad ZukarnainVarious types of natural phenomena are regarded as primary sources of information for artificial occurrences that involve spontaneous synchronization. Among the artificial occurrences that mimic natural phenomena are Wireless Sensor Networks (WSNs) and the Pulse Coupled Oscillator (PCO), which utilizes firefly synchronization for attracting mating partners. However, the PCO model was not appropriate for wireless sensor networks because sensor nodes … …Journal of Computer Science, Vol. 12, Issue 10 · 11 Dec 2016 · 7,710 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComparative Study on Energy Efficient in Traveling Wave Pulse Coupled Oscillator for Wireless Sensor NetworksZeyad Ghaleb Al-Mekhlafi, Zurina Mohd Hanapi, Mohamed Othman, Zuriati Ahmad ZukarnainWSNs are unable to afford simultaneous transmission and reception of data and for most scenarios, the battery replacement is impossible upon the exhaustion of a node's battery energy. Thus, energy efficient protocols constitute vital design requirements for the WSN as a whole in order to increase the lifetime and ensure successful transmission of data from sensor node source to target, … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 21 Nov 2016 · 7,355 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA TIME SYNCHRONIZED HYBRID VEHICULAR AD HOC NETWORK OF ROADSIDE SENSORS AND VEHICLES FOR SAFE DRIVINGDahlia Sam, V. Cyril RajVANET is a type of ad hoc network in which the moving vehicles act as nodes. There has been lot of research for using VANETs in many applications. One of the main applications is the use of VANETs to improve driving safety. In any safety related applications, the vehicular nodes have to constantly communicate with each other and the roadside … …Journal of Computer Science, Vol. 10, Issue 9 · 10 Apr 2014 · 8,109 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOPTIMIZING LOCALIZATION ROUTE USING PARTICLE SWARM-A GENETIC APPROACHL. Lakshmanan, D. C. TomarOne of the most key problems in wireless sensor networks is finding optimal algorithms for sending packets from source node to destination node. Several algorithms exist in literature, since some are in vital role other may not. Since WSN focus on low power consumption during packet transmission and receiving, finally we adopt by merging swarm particle based algorithm with genetic … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 20 Jan 2014 · 7,381 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCLUSTER BASED ARCHITECTURE FOR LOCALIZATION AND TRACKING IN WIRELESS SENSOR NETWORKP. Prabhakaran, Nelson Kennedy BabuWireless sensor networks are an efficient way of reading and transmitting information through a system of controls. They are used for a variety of purposes. The signals passed between each sensing unit and the central control unit needs to be theoretically nonexistent for perfect transmission but there are many hindrances like transmission techniques and physical disturbances which cause delay. Here … …Journal of Computer Science, Vol. 10, Issue 5 · 17 Jan 2014 · 6,796 accessesView PDFCite
