Research ArticleOpen accessPhrase in the titleCross-Layer Design for Reducing the Energy Consumption based on Mobility Parameter in DSR for Mobile Ad-Hoc NetworkV. Bhanumathi, R. DhanasekaranProblem statement: The main idea is to design an energy efficient algorithm for reducing the amount of overhearing based on RSS value in a Mobile Ad-hoc Network (MANET). Approach: A cross layer framework is designed by combining the physical, MAC and network layer. RSS value is taken from the physical layer and it is used for finding the Mobility Parameter … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 6,814 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePerformance Study of Ad-Hoc Reactive Routing ProtocolsPallavi Khatri, Monika Rajput, Alankar Shastri, Keshav SolankiProblem statement: In this study, an attempt had been made to compare the performance of the reactive ad-hoc routing protocols using OPNET modeler with respect to increasing number of nodes in the network. Approach: In present study, we compared various reactive routing protocols such as Ad hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Temporally Ordered Routing Algorithm … …Journal of Computer Science, Vol. 6, Issue 10 · 10 Aug 2010 · 7,753 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleAn Algorithm for Localization in Vehicular Ad-Hoc NetworksHajar Barani, Mahmoud FathyPositioning a node in Vehicular Ad-Hoc networks is one of the most interested research areas in recent years. In many Ad-Hoc networks such as Vehicular Ad-Hoc networks in which the nodes are considered as vehicles, move very fast in streets and highways. So, to have a safe and fast transport system, any vehicle should know where a traffic problem such … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,363 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleLocal Beam Search Algorithm for Power Saving in Clustered Ad-Hoc NetworksA. Zabian, F. Al-KalaniAn ad-Hoc network is an infrastructures network consisting of mobile moving nodes. Every node in network performs as a router or a package forwarder. Energy consumption of network interfaces can be significant. There is a relationship between the transmission power and the distance traveled by a packet, increasing the transmission power increases the reachable area at the cost of high … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,539 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePerformance Comparison of Two On-demand Routing Protocols for Ad-hoc Networks based on Random Way Point Mobility ModelGeetha Jayakumar, G. GopinathAd hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols plays an important role. We compare the performance of two prominent on-demand routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On-demand distance Vector Routing (AODV). A detailed simulation model with MAC and physical layer … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,692 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePower 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 accessPhrase in the titleTopology 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. However, there are a trade off between the power consumption and the connectivity in mobile networks. We present a topology control mechanism and a routing protocol for Ad-Hoc wireless networks that chooses the shortest path given the lower power … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,550 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleLocation Based Throughput Maximization Routing in Energy Constrained Mobile Ad-hoc NetworkV. Sumathy, P. Narayanasamy, R. PrabhuIn wireless Ad-hoc network, power consumption becomes an important issue due to limited battery power. One of the reasons for energy expenditure in this network is irregularly distributed node pattern, which impose large interference range in certain area. To maximize the lifetime of ad-hoc mobile network, the power consumption rate of each node must be evenly distributed and the over … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,823 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleConstructing Longest Lifetime Route in Mobile Ad-hoc NetworksFredrick Mtenzi, Yingyu WanA mobile ad hoc network (MANET) is an autonomous system consisting of mobile hosts connected by wireless links. Every host can move in any direction at any speed and time. This leads to a dynamic topology as hosts move constantly. MANET broadcast messages to each hosts, the transmission of one host can be heard by all hosts in its communication … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 4,936 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleImproving Routing Discovery Based Velocity-Aware Probabilistic Using AODV with Link Prediction in Mobile Ad-hoc NetworksZaid BassfarThe current process associated with enhancing the QoS in routing for MANETs has reserved a high importance due to the limitation of available route discovery in dynamic topology. The conventional methods of route discovery schemes in MANETs are commonly designed in order to estimate the number of nodes in routes using the standard probabilistic models. Such models are utilized by … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 1 Aug 2017 · 7,655 accessesView PDFCite
