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 abstractImpact of Asymmetric Encryption Algorithms in a VANETEdward David Moreno, Leila C.M. Buarque, Florêncio Natan et al.This paper describes the impact of using asymmetric encryption algorithms, with emphasis on RSA, ECC and Multivariate Quadratic Quasigroup (MQQ) algorithms, in a scenario of Vehicular Ad hoc Network (VANET). In the research we used the simulator NS-3 with specific module for vehicular networks. The algorithms were implemented in C and were included in NS-3. The results, even in a … …Journal of Computer Science, Vol. 11, Issue 12 · 30 Jan 2016 · 6,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractFORMAL VERIFICATION OF SAFETY MESSAGE DISSEMINATION PROTOCOL FOR VANETSM. A. Berlin, Sheila AnandThis paper presents a formal verification of a safety message dissemination protocol used in vehicular ad-hoc networks. It is proposed to use Road Side Units to broadcast road hazard information to vehicles travelling on highways. Quick dissemination of road hazard information, like road blocks, slippery roads and other obstacles can help to prevent road accidents and improve passenger safety. Formal … …Journal of Computer Science, Vol. 9, Issue 8 · 9 Jul 2013 · 6,858 accessesView PDFCite
Research ArticleOpen accessIn the abstractArtificial Bee Colony based Energy Aware and Energy Efficient Routing ProtocolP. Visu, S. Koteeswaran, J. JanetProblem statement: Network becomes very important technology in the day to day life style of modern computer era, in which the wireless communication become very popular for the last few years. In the same manner, the other wireless network, i.e., ado network is very popular among the researchers in the past few decades. Approach: The Ad hoc networks are defined … …Journal of Computer Science, Vol. 8, Issue 2 · 19 Jan 2012 · 7,095 accessesView PDFCite
Research ArticleOpen accessIn the abstractCollaborative Caching Architecture for Continuous Query in Mobile DatabaseMohamed Ahmed Elfaki, Hamidah Ibrahim, Ali Mamat, Mohamed OthmanProblem statement: Cooperative caching, which allows sharing and coordination of cached data among clients, is a potential technique to improve the data access performance and availability in mobile ad hoc networks. However, variable data sizes, frequent data updates, limited client resources, insufficient wireless bandwidth and client’s mobility make cache management faces many challenges. Approach: In this study, we propose a … …American Journal of Economics and Business Administration, Vol. 3, Issue 1 · 7 Jan 2011 · 8,875 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAN EFFICIENT HYBRID ALGORITHM TO REDUCE LATENCY IN AD-HOC AGGREGATIONN. Rajkumar, N. K. Senthil Kumar, P. Subha, R. KavithaA data warehouse is a collection of data gathered and organized so that it can easily be analyzed, extracted, synthesized and also be used for the purpose of further understanding data. Peer to Peer networks are used for distribution and sharing of documents. In traditional techniques, when aggregate functions like average, sum and count are encountered, the aggregate operation is … …Journal of Computer Science, Vol. 10, Issue 7 · 18 Feb 2014 · 6,908 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA PREEMPTIVE LINK STATE SPANNING TREE SOURCE ROUTING PROTOCOL FOR MOBILE ADHOC NETWORKSPoonkuzhali Ramadoss, Sanavullah Mohamed Yakub, Sabari AnnajiRouting protocol is a central issue in Mobile Adhoc Networks (MANET). Several routing protocols have been proposed to deal with the routing issue in MANETs. Routing is a complex task in MANET, if the network is heavily loaded. In this study a new QoS routing protocol is proposed which provides better path selection by avoiding congestion, balancing the load and … …Journal of Computer Science, Vol. 10, Issue 1 · 12 Nov 2013 · 6,991 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Fault Tolerant Congestion Aware Routing Protocol for Mobile Adhoc NetworksG. Rajkumar, K. DuraiswamyProblem statement: The performance of ad hoc routing protocols will significantly degrade when there are faulty nodes in the network. Packet losses and bandwidth degradation are caused due to congestion and thus, time and energy is wasted during its recovery. The fault tolerant congestion aware routing protocol addresses these problems by exploring the network redundancy through multipath routing. Approach: In … …Journal of Computer Science, Vol. 8, Issue 5 · 23 Feb 2012 · 6,446 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Analysis of Power Aware Congestion Control Multipath Multicast Protocol for Mobile Ad hoc NetworkDuraiswamy Karuppaswamy, Vijayaragavan ShanmugamProblem statement: In MANETs, wireless link transmission errors, mobility and congestion are major causes for packet loss. Mobility may cause packet loss in different ways. Whereas congestion in a network occurs, whenever the demands exceed the maximum capacity of a communication link especially when multiple hosts try to access a shared media simultaneously. Approach: In this study, we proposed a … …Journal of Computer Science, Vol. 6, Issue 12 · 2 Nov 2010 · 7,038 accessesView PDFCite
