Research ArticleOpen accessIn the keywordsCongestion Free Routing in Adhoc NetworksT. Senthil Kumaran, V. SankaranarayananProblem statement: A Mobile Ad-Hoc Network (MANET) is a temporary network; the mobile devices in an ad-hoc network are communicating through wireless links without any pre-existing infrastructure. The one major problem of this network is network congestion, it may take place at any intermediate nodes when data packets are traveling from source to destination. The major problems of congestion or … …Journal of Computer Science, Vol. 8, Issue 6 · 4 Apr 2012 · 7,240 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA 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 · 6,449 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTopology Control Using Efficient Power ManagementS. Karunakaran, P. ThangarajProblem statement: Effective Topology control will improve the performance and the capacity of Mobile Ad-hoc networks by building reliable network structure. Approach: Power level is used as the basis for topology control since it reduces spatial interference while increasing the effective channel capacity and network lifetime. Results: In this study, we design a topology control using efficient power management algorithm … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 6,718 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA 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 · 6,946 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFL-CARE: Federated Learning-Based Contention-Aware and Energy-Balanced Routing for Dense FANETsHalimjon Khujamatov, Elyanora Jolimbetova et al.In dense multi-drone FANET environments, routing efficiency is often reduced due to constant competition for a wireless channel, frequent changes in network topology, and uneven energy consumption between UAV nodes. These factors lead to a decrease in the packet delivery ratio, an increase in delays on the busiest or most unstable routes, and a reduction in the total network lifespan. … …Journal of Computer Science, Vol. 22, Issue 8 · 13 Aug 2026 · 1,181 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Efficient Cluster Head Selection in IoV-Enabled VANETs Using a Federated Diffusion Convolutional Recurrent Neural Networks FrameworkP Subhash, Madana Srinivas, A. Ranjith et al.The IoV enables the formation of VANETs that require a strong selection of CHs for effective communication within high-velocity changing traffic scenarios. Existing approaches often face issues related to scalability, privacy, and adaptability. To meet the aforementioned urgent needs, we design a decentralized scheme for intelligent CH selection based on Federated Learning with Diffusion Convolutional Recurrent Neural Networks (DCRNNs). According … …Journal of Computer Science, Vol. 22, Issue 10 · 1 Oct 2026 · 612 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSecurity Mechanism for Vehicle Identification and Transaction Authentication in the Internet of Vehicle (IoV) Scenario: A Blockchain Based ModelMirador Labrador, Weiyan HouInternet of Vehicle (IoV) is now changing the landscape of Transportation System-paving the way of the so called Intelligent Transport System as it is being powered by the plethora of converging smart sensors and technologies. However, beyond its potential, this technology is still in a ground zero level considering the many facets of issues and concerns that needs to be … …Journal of Computer Science, Vol. 15, Issue 2 · 13 Feb 2019 · 8,195 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA 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 · 6,993 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMobility Management for Seamless Information Flow in a Heterogeneous NetworksAdiline Macriga, AnandhakumarProblem statement: In the heterogeneous networks, generally the entire networks operating on the Radio Frequencies under wireless mode available for communication are brought under a single head based on their common operating procedures and functions. As a common mode the basic functions of the networks are requesting, tracing, sending, acknowledging, authenticating, authorizing, receiving, updating, forwarding, controlling, registering, managing. As the … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 6,891 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Novel Routing Protocol with High Energy Performance in Mobile Special NetworksAli Norouzi, B. Berk UstundagProblem statement: Mobile Special Networks do not have a predetermined structure. This type of networks can dynamically reorganize network connection relationships due to change of neighborhoods and the relative positions. Approach: There are many problems in creation of a special network such as routing, wireless media, energy consumption and transportability. Results: Although these networks primarily had been formed for small … …Journal of Computer Science, Vol. 7, Issue 1 · 15 Jan 2011 · 7,306 accessesView PDFCite
