Research ArticleOpen accessIn the abstractAuthentication Based and Optimized Routing Technique in Mobile Ad hoc NetworksS. Varadhaganapathy, A. M. Natarajan, S. N. SivanandamProblem statement: An Ad hoc network has been defined as a self-organizing, dynamic topology network formed by a group of wireless mobile nodes. Minimal configuration, absence of infrastructure and quick deployment, would make ad hoc networks convenient for emergency situations other than military applications. In recent years, security in Ad hoc Networks as a research topic had started to receive … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractTopological Decoupled Group Key Management for Cellular NetworksJorge Estudillo Ramirez, Saul Eduardo Pomares Hernandez, Gustavo Rodriguez Gomez, Jose Roberto Perez CruzProblem statement: The continuous increasing capacity of the cellular networks motivates the development of multiparty applications, such as interactive mobile TV and mobile social networks. For these environments, security group services are required. A practical way to provide security services is by using cryptographic methods. However, the key management needed for these methods, which considers a dynamic group membership, introduces … …Journal of Computer Science, Vol. 7, Issue 3 · 9 Mar 2011 · 6,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fault Tolerant Mobile Agent Information Retrieval SystemR. Punithavathi, K. DuraiswamyProblem statement: Most of the information retrieval systems used only client-server architectures. The client-server model though powerful, had some limitations. In mobile computing environment which has both wired network and wireless networks with limited communication capabilities, the performance of the system was very low. Approach: Mobile agents are considered a suitable technology to develop applications such as information retrieval system … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 7,203 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Framework for Group Key Management Protocol Assessment Independent of View SynchronyDavid Manz, Paul Oman, Jim Alves-FossProblem statement: As group key management extended into the area of large dynamic networks, complex issues emerged involving the many operations that run over several network topologies. The issues that occurred due to multiple topologies were also compounded by differing views of the network, taken at different time slices or positions within the network. This was especially complex when figuring … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 6,942 accessesView PDFCite
Research ArticleOpen accessIn the abstractArabic Short Text CompressionIman Omer, Khalaf KhatatnehProblem statement: Text compression permits representing a document by using less space. This is useful not only to save disk space, but more importantly, to save disk transfer and network transmission time. With the continues increase in the number of Arabic short text messages sent by mobile phones, the use of a suitable compression scheme would allow users to use … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Light-Weight Service Discovery Protocol for Ad Hoc NetworksRanwa Al Mallah, Alejandro QuinteroProblem statement: In mobile ad hoc networks devices do not rely on a fixed infrastructure and thus have to be self-organizing. This gives rise to various challenges to network applications. Existing service discovery protocols fall short of accommodating the complexities of the ad-hoc environment. However, the performance of distributed service discovery architectures that rely on a virtual backbone for locating … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,336 accessesView PDFCite
Research ArticleOpen accessIn the abstractVirtual Mobility to Improve Cooperation in Mobile Ad hoc NetworksA. Baaziz, S. PierreWe study the impact of mobility on the level of cooperation between mobile nodes in a mobile ad hoc network. In a mobile ad hoc network, if the nodes are static or have a reduced mobility and if some nodes adopt a selfish behaviour, the performance of the network is affected. This is because the same nodes that are relaying … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 6,955 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecreasing 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 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 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
