Research ArticleOpen accessPhrase in the titleAn Enhanced Dynamic Source Routing Algorithm for the Mobile Ad-Hoc Network using Reinforcement learning under the COVID-19 ConditionsEhsan Moqimi, Amir Najafi, Mojtaba AjamiToday, the use of computer networks is evident in all walks of life, including mobile phones, vehicles, personal computers, the workplace and more. Creating and operating networks between each of the above-mentioned devices require good infrastructure to be able to communicate between these devices. To solve this problem, there were networks called ad-hoc networks, which were able to network with … …Journal of Computer Science, Vol. 16, Issue 10 · 31 Oct 2020 · 6,994 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleSocialMANET: A Publish/Subscribe Events Dissemination Protocol for Mobile Ad-Hoc NetworksMaurice Tchoupé Tchendji, Martin Xavier Tchembé, Innocent Tialo NecheuThe popularization of mobile equipment capable of communicating autonomously nowadays offers the possibility of thinking more seriously about a mode of communication in which stakeholders communicate in an ad-hoc manner and use mobility to convey information. However, due to their mobile nature, such equipments are limited by their low energy and storage capacity. Algorithms designed for them must therefore be … …Journal of Computer Science, Vol. 15, Issue 9 · 3 Sep 2019 · 7,681 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePERFORMANCE EVALUATION OF WORMHOLE SECURITY APPROACHES FOR AD-HOC NETWORKSIsmail Hababeh, Issa Khalil, Abdallah Khreishah, Samir BatainehAd-hoc networks are talented but are exposed to the risk of wormhole attacks. However, a wormhole attack can be mounted easily and forms stern menaces in networks, particularly against various ad-hoc wireless networks. The Wormhole attack distorts the network topology and decrease the network systems performance. Therefore, identifying the possibility of wormhole attacks and recognizing techniques to defend them are … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 6,618 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleQuality of Service Aware Reverse Pathad-Hoc On-Demand Distance Vector ProtocolK. G. Santhiya, N. ArumugamMobile Ad-hoc Network (MANET) is aninfra structureless network that does not require any built-in infra structure and central control. Due to very fast mobility of nodes, there will be drastic changes in the network topology. So an adaptive routing protocol is needed for effective and reliable routing in MANET. Ad-hoc On-demand Distance Vector (AODV) routing protocol is the efficient and … …Journal of Computer Science, Vol. 8, Issue 11 · 20 Sep 2012 · 7,061 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleE2AODV Protocol for Load Balancing in Ad-Hoc NetworksR. Vinod Kumar, R. S.D. Wahida BanuProblem statement: In mobile ad hoc networks there are a number of challenges in providing quality of service routing with energy efficiency and load balancing. Most routing protocols do not consider the problem of load balance. A routing protocol called energy Efficient Ad-hoc on Demand Vector (E2AODV) is proposed. It addresses the quality of service issues such as throughput, end … …Journal of Computer Science, Vol. 8, Issue 7 · 7 Jul 2012 · 6,832 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleDensity Based Routing Algorithm for Spare/Dense Topologies in Wireless Mobile Ad-Hoc NetworksEssam Natsheh, Khalid BuraggaProblem statement: A Mobile Ad-Hoc Networks (MANETs) operate in environments without infrastructures with an undefined network size. Most routing protocols of Mobile Ad-hoc Networks (MANETs) were studied using open space models where nodes were able to move throughput the entire simulation area. However, a more realistic topology should account for restricted mobility of nodes, such as in an urban city … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,461 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleNodes Density and Broadcast Management in Heterogeneous Environments of Mobile Ad-Hoc NetworksEssam Natsheh, Khalid BuraggaProblem statement: The research presented in this study looks into Mobile Ad-Hoc Networks (MANETs) environment that has varying node densities, called heterogeneous density environment. Such environment can be roughly associated with situations varying from areas struck by disasters to normal city environments. Approach: This study improved the performance of existing MANETs routing protocols by reducing the communication overhead incurred during … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,330 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Novel Approach to Modeling and Flooding in Ad-hoc Wireless NetworksO. Issaad, S. Pierre, G. I. Ivascu, O. GarciaThis study proposes a new modeling approach for wireless ad-hoc networks. The new approach is based on the construction of fuzzy neighborhoods and essentially consists of assigning a membership or importance degree to each network radio link which reflects the relative quality of this link. This approach is first used to model the flooding problem and then an algorithm is … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,015 accessesView PDFCite
Research ArticleOpen accessPhrase 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 accessPhrase in the titleArithmetic Encoding Based Dynamic Source Routing for Ad-Hoc NetworksAjay Koul, R. B. Patel, V. K. BhatAn ad hoc network is a collection of mobile stations forming a temporary network without the aid of any centralized coordinator. Routing messages are an essential component of Mobile Adhoc Networks, as each packet needs to be passed quickly through intermediate nodes from source to destination. Internal threats due to changes in the node behaviour that target the routing discovery … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 6,604 accessesView PDFCite
