Research ArticleOpen accessEvery word in the titleDecreasing Overhead and Power Consuming in Ad-Hoc Networks by Proposal a Novel Routing AlgorithmA. Barati, A. Movaghar, H. Barati, A. Azizi MazreahAn Ad-Hoc network has been constructed from a fabric of mobile nodes intercom connected by temporary wireless links. Nodes located beyond a single hop are reached using intermediate neighbors to forward messages over long distances. The problem with this method of communication is that mobility causes the network topology to be unstable. Traditional solutions maintain routes by exchanging information when … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,800 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Strategy for Signaling Overhead Reduction in the Proxy Mobile IPv6 ProtocolAdnan J. Jabir, S. Shamala, Z. ZuriatiProblem statement: The rapid growth of the Internet usage has been realized by the Mobile IPv6 (MIPv6). Concurrent to these technological advances is the communication overheads. Proxy Mobile IPv6 (PMIPv6) has been standardized to overcome the long handoff latency, packet loss and signaling overhead of MIPv6 and to exempt the mobile node from any involvement in the handoff process. Although … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 13 Feb 2012 · 7,500 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVarying Overhead Ad Hoc on Demand Vector Routing in Highly Mobile Ad Hoc NetworkV. Balaji, V. DuraisamyProblem statement: An inherent feature of mobile ad hoc networks is the frequent change of network topology leading to stability and reliability problems of the network. Highly dynamic and dense network have to maintain acceptable level of service to data packets and limit the network control overheads. This capability is closely related as how quickly the network protocol control overhead … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,997 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReducing Broadcast Overhead Using Clustering Based Broadcast Mechanism in Mobile Ad Hoc NetworkN. Karthikeyan, V. Palanisamy, K. DuraiswamyProblem statement: Network wide broadcasting is an important function in Mobile Ad Hoc Networks (MANET), which attempts to deliver packets from a source node to all other nodes in the network. Broadcasting is often very useful for route discovery, naming, addressing and helping multicast operations in all kinds of networks. For designing broadcast protocols for ad hoc networks, one of … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 7,031 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Novel Proactive Routing Method for Mobile Ad Hoc NetworksBambrik Ilyas, Didi FedouaIn recent years, the Mobile Ad hoc Networks (MANETs) became more popular due to their multiple advantages such as the low setup cost, auto-configuration and auto-healing features. This kind of network is distinguished by its dynamic and distributed nature since it does not contain any form of centralized infrastructure. These characteristics have led to the emergence of new routing protocols … …American Journal of Applied Sciences, Vol. 12, Issue 6 · 23 Jul 2015 · 6,376 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEXTENDED-RANDOMIZED, EFFICIENT, DISTRIBUTED: A DYNAMIC DETECTION OF CLONE ATTACKS IN STATIC WIRELESS SENSOR NETWORKSC. Geetha, M. RamakrishnanA wireless sensor network is a collection of nodes organized in to a cooperative network. Each node consists of processing capability, multiple types of memory, a power source and actuators and sensors. This wireless sensor network is established in hostile and harsh environments like civil and military applications. This network is prone to various attacks. One of the major attack … …Journal of Computer Science, Vol. 10, Issue 10 · 6 May 2014 · 6,742 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpulse Radio Ultra Wide Band Based Mobile Adhoc Network Routing Performance AnalysisM. Sreedhar, C. VenkateshThis study presents with the routing overhead analysis of impulse radio - Ultra Wide Band based wireless networks which Employs Dynamic Nature Routing (EDNR) method for determining and selecting the stable route in Mobile Adhoc Network (MANET). This method requires only two sample packets and uses piggyback information on Route-Request (RREQ) and Route-Reply (RREP) packets during a route-discovery procedure. Conventional … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 15 Apr 2013 · 5,887 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRealization 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 keywordsMobility and Density Aware AODV Protocol Extension for Mobile Adhoc Networks-MADA-AODVS. Deepa, G.M. Kadhar NawazProblem statement: In this study, we proposed a method to improve the performance of AODV by reducing overhead by adopting a route message propagation mechanism. According to the new scheme, a node will be selected to forward a routing request message if and only if a condition based on its mobility (speed) and number of neighbors is satisfied. If the … …Journal of Computer Science, Vol. 8, Issue 1 · 26 Oct 2011 · 7,282 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBalanced Scheduling of Independent File-Sharing Tasks in Heterogenous EnvironmentR. K. Ponsy, Sathia Bhama, S. Thamarai SelviProblem statement: To examine the strategies for scheduling of independent file-sharing tasks in a heterogeneous environment and the concept of load balancing. Approach: We propose hypergraph partitioning based strategy for the scheduling of non-critical jobs. This is done by scheduling the tasks that share tasks among them to the same processor. The tasks thus scheduled are employed to a load … …Journal of Computer Science, Vol. 7, Issue 12 · 17 Oct 2011 · 6,776 accessesView PDFCite
