Research ArticleOpen accessIn the abstractReducing 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 abstractPriority and Random Selection for Dynamic Window Secured Implicit Geographic Routing in Wireless Sensor NetworkZurina Mohd Hanapi, Mahmod Ismail, Kasmiran JumariProblem statement: Sensor nodes are easily exposed to many attacks since it were deployed in unattended adversarial environment with no global addressing and used for critical applications such as battlefield surveillance and emergency response. While the sensor also needs to act as a router to relay a message to a required recipient, then this increased the vulnerabilities to a network … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,652 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of Taguchi Method to Determine Factors Affecting the Performance of Destination Sequence Distance Vector Routing Protocol in Mobile Ad Hoc NetworksHazura. Mohamed, Muhammad Hisyam Lee, Mazalan Sarahintu et al.In this study, Taguchi method was used to identify the several factors that may affect the performance of Destination Sequence Distance Vector (DSDV) routing protocol. The performance of DSDV routing protocol in mobile ad hoc networks were greatly influence by factors such as node speed, node pause time and traffic load. Problem statement: By using orthogonal experimental design and analysis … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,797 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Routing Technique against Packet Dropping Attack in Adhoc NetworksN. Bhalaji, Sinchan banerjee, A. ShanmugamProblem Statement: Mobile adhoc networks (MANETs) were extensively used in defense and rescue applications. The dynamic topology of MANETs allows nodes to join and leave the network at any point of time. This dynamic property of MANET has rendered it vulnerable to various security attacks. Many trust establishment methods were proposed to increase the security in MANET. In this paper … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance 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 accessIn the abstractAnt Colony Based Node Disjoint Hybrid Multi-path Routing for Mobile Ad Hoc NetworkB. Kalaavathi, K. DuraiswamyMobile Ad hoc Networks are characterized by multi-hop wireless links, without any infrastructure and frequent node mobility. A class of ant colony based routing protocols has recently gained attention because of their adaptability to the network changes. AntHocNet is ant colony based hybrid algorithm, which combines reactive path setup with proactive path probing, maintenance and improvement. Multi-path routing represents a … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Swarm-based Distance Vector Routing to Support Multiple Quality of Service (QoS) Metrics in Mobile Adhoc NetworksR. Asokan, A. M. Natarajan, A. NivethaQuality of Service support for Mobile Ad-hoc Networks is a challenging task due to dynamic topology and limited resource. The main purpose of QoS routing is to find a feasible path that has sufficient resources to satisfy the constraints. A fundamental problem in QoS routing is to find a path between a source and destination that satisfies two or more … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractProximity Aware Routing in Ad Hoc NetworksValerie Alandzi, Alejandro QuinteroMost of the existing routing protocols for ad hoc networks are designed to scale in networks of a few hundred nodes. They rely on state concerning all links of the network or links on the route between a source and a destination. This may result in poor scaling properties in larger mobile networks or when node mobility is high. Using … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,733 accessesView PDFCite
