Research ArticleOpen accessIn the abstractAn Optimized Ad Hoc on Demand Distance Vector Routing Protocol for Wireless NetworksV. Ponniyin Selvan, S. Senthil KumarProblem statement: Wireless Mesh Networks (WMN) is communication network made up of mesh routers and mesh clients, with mesh routers forming the backbone of the network. The WMN can be accessed by other networks through gateways and bridging functions in the mesh routers. The mesh clients can either be static or mobile with an option of forming a client mesh … …Journal of Computer Science, Vol. 8, Issue 7 · 21 Jun 2012 · 7,168 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultipath Routing Protocol for Effective Local Route Recovery in Mobile Ad hoc NetworkD. Jagadeesan, S. K. SrivatsaProblem statement: In mobile ad hoc networks, frequent mobility during the transmission of data causes route failure which results in route rediscovery. In this, we propose multipath routing protocol for effective local route recovery in Mobile Ad hoc Networks (MANET). In this protocol, each source and destination pair establishes multiple paths in the single route discovery and they are cached … …Journal of Computer Science, Vol. 8, Issue 7 · 8 Jun 2012 · 6,934 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Radio Propagation Models on Ad Hoc Networks PerformancesA. Rhattoy, A. ZatniProblem statement: Wireless networks are characterized by a dynamic topology triggered by the nodes mobility. Thus, the wireless multi-hops connection and the channel do not have determinist behaviour such as: Interference or multiple paths. Moreover, the nodes’ invisibility makes the wireless channel difficult to detect. This wireless networks’ behaviour should be scrutinized. Approach: In our study, we mainly focus on … …Journal of Computer Science, Vol. 8, Issue 5 · 2 Mar 2012 · 6,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Malicious Nodes under Different Route Refresh Intervals in Ad Hoc NetworkP. Suganthi, A. TamilarasiProblem statement: Ad hoc networks are formed dynamically by group of mobile devices co operating with each other. Intermediate nodes between source and destination act as routers so that source node can communicate with the destination node even if it is out radio range and thus eliminating the necessity of infrastructure. Co operation of nodes is a very important feature … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 3 Nov 2011 · 7,305 accessesView PDFCite
Research ArticleOpen accessIn the abstractVarying Overhead Ad Hoc on Demand Vector Routing in Highly Mobile Ad Hoc NetworkV. Balaji, V. DuraisamyProblem statement: An inherent feature of mobile ad hoc networks is the frequent change of network topology leading to stability and reliability problems of the network. Highly dynamic and dense network have to maintain acceptable level of service to data packets and limit the network control overheads. This capability is closely related as how quickly the network protocol control overhead … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,000 accessesView PDFCite
Research ArticleOpen accessIn the abstractTopology 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 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 · 8,882 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Ad Hoc on Demand Distance Vector Routing Protocol in HetMAN ArchitectureZahian Ismail, Rosilah HassanProblem statement: Mobile Ad hoc Network (MANET), a type of network with special characteristics, needs a special mechanism to bear with its ad hoc behavior. Approach: The important issue in MANET is routing protocol. Routing protocol is a standard used to determine the route path taken during the transmission of data. Results: In this study we focused on the Ad … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 6,336 accessesView PDFCite
Research ArticleOpen accessIn the abstractSafety Message Power Transmission Control for Vehicular Ad hoc NetworksGhassan Samara, Sureswaran Ramadas, Wafaa A.H. Al-SalihyProblem statement: Vehicular Ad hoc Networks (VANET) is one of the most challenging research area in the field of Mobile Ad Hoc Networks. Approach: In this research we proposed a dynamic power adjustment protocol that will be used for sending the periodical safety message. (Beacon) based on the analysis of the channel status depending on the channel congestion and the … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Jul 2010 · 7,470 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 · 6,946 accessesView PDFCite
