Research ArticleOpen accessIn the abstractReliable and Efficient Broadcasting in Asymmetric Mobile Ad Hoc Networks Using Minimized Forward Node List AlgorithmMarimuthu Murugesan, Ammasai KrishnanProblem statement: Network wide broadcasting is a fundamental operation in ad hoc networks. In broadcasting, a source node sends a message to all the other nodes in the network. Unlike in a wired network, a packet transmitted by a node in ad hoc wireless network can reach all neighbors. Therefore, the total number of transmissions (Forwarding nodes) used as the … …Journal of Computer Science, Vol. 7, Issue 1 · 27 Dec 2010 · 7,580 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMinimising Energy Consumption in WSN-IoT Networks by Focusing on Quality of ServiceAnuradha, Tarun Gulati, Rajbhupinder Kaur et al.IoT networks are low-powered networks and resource allocation and efficient utilization are critical concerns. Network resources are allocated to the intermediate nodes to perform the various operations (sense, transmit, re-transmit, data aggregation, etc.). These operations are managed by the different layers (M.A.C., routing and PHY). Each layer consumes resources W.R.T. their operations and there is a need to manage the … …Journal of Computer Science, Vol. 20, Issue 10 · 13 Aug 2024 · 4,984 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordInvestigations on Orthogonal-Frequency Division Multiplexed-Mode-Division Multiplexed MM Wave-on-Free Space Optics Transmission using Laguerre-Gaussian Modal BeamsAnita Suman, Ajay KumarWe report the simulation-modelling and evaluation of an integrated Orthogonal-Frequency Division Multiplexed (OFDM)-Mode-Division Multiplexed (MDM) Radio-on-Free Space Optics (Ro-FSO) scheme carrying 2-independent 40 GHz millimetre waves (mm Wave) at 20 Gbps per channel for 5th generation wireless applications. The reported Ro-FSO scheme transports 2-independent 20 Gbps 4-Quadrature-Amplitude Modulated (4-QAM) signals, each carrying 40 GHz mm Wave signal over 2-distinct Laguerre-Gaussian … …Journal of Computer Science, Vol. 17, Issue 12 · 15 Dec 2021 · 6,204 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 · 7,358 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA LEADER BASED MONITORING APPROACH FOR SINKHOLE ATTACK IN WIRELESS SENSOR NETWORKD. Udaya Suriya Rajkumar, Rajamani VayanaperumalSecurity is one of an important factor to be considered seriously in wireless sensor networks. In WSN, in many ways intrusion may occur, in the past decades there is no perfect IDS, without any wasting of resources like time, energy, cost and number of physical items. The main objective is to ensure the security and improve the quality of network … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,917 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTRANSMISSION CONTROL PROTOCOL PERFORMANCE COMPARISON USING PIGGYBACK SCHEME IN WLANSAli Ahmad Milad, Zul Azri Bin Muhamad Noh, Abdul Samad Shibghatullah et al.The main problem at wireless networks is the overhead at MAC layer; when the data physical rate is increasing it causes increasing the overhead and decreasing at the MAC efficiency. In this study we study the performance comparison of TCP protocol in WLANs with and without using piggyback. The study of results concerning of implemented both mechanisms in NS2 simulator … …Journal of Computer Science, Vol. 9, Issue 8 · 2 Jul 2013 · 7,366 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordApplication of Newton Raphson Algorithm for Optimizing Transmission Control Protocol PerformanceJ. Viji Priya, S. SuppiahWireless networks are growing rapidly. TCP is the most widely-used protocol on Internet and so optimizing TCP performance is very important for fast efficient data transfer. The different existing TCP variants and solutions they have not been analyzed together to identify the bottlenecks in wireless networks. TCP has a major problem in its congestion control algorithm which does not allow … …Journal of Computer Science, Vol. 9, Issue 5 · 20 May 2013 · 6,306 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMultiple-Input Multiple-Output Transmission Over a Multipath Faded ChannelsI.A.Z. QatawnehThe use of multiple antennas at the transmitter as well as at the receiver can greatly improve the capacity of a wireless link when operating in a rich scattering environment. In such an arrangement all transmitting antennas radiate in the same frequency band so the overall spectral efficiency becomes very high. Such a multiple antenna scheme, popularly known as Multiple … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 11 Mar 2013 · 6,420 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordRRDVCR: Real-Time Reliable Data Delivery Based on Virtual Coordinating Routing for Wireless Sensor NetworksVenkatesh, Chanchal Singh Sengar, Kuppanna Rajuk Venugopal et al.Real-time industrial application requires a routing protocol that guarantees data delivery with reliable, efficient and low end-to-end delay. Existing Two-Hop Velocity based Routing (THVR) protocol relates two-hop velocity to end-to-end delay to select the next forwarding node, that has the overhead of exchanging control packets and depleting the available energy in nodes. We propose a Real-Time Reliable Data delivery based … …Journal of Computer Science, Vol. 14, Issue 1 · 3 Jan 2018 · 8,237 accessesView PDFCite
