PurusothamanProblem statement: This study describes about a robust and secured authentication procedure that can be adapted in a private forum within a Social Network Site (SNS) to update its user’s profile. Approach: The robustness is achieved through combining proven security measures combined with usability aspects. The study demonstrates acceptance of such robustness particularly in a SNS to update user’s profile. … …Journal of Computer Science, Vol. 7, Issue 8 · 14 Jul 2011 · 6,594 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntegrating Buffer Management with Epidemic Routing in Delay Tolerant NetworksG. Fathima, R. S.D. WahidabanuProblem statement: The Design of Delay Tolerant Network (DTN) routing protocols has focused to operate in an environment where there is no guarantee of end to end path between source and destination at all points of time. The DTN research has focussed primarily on applications that are delay tolerant. But it can also be used to provide real time information … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 7,080 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparative Performance Evaluation of Routing Algorithms in IEEE 802.15.4 and IEEE 802.11 with Different Ad Hoc Routing ProtocolP. Anitha, C. ChandrasekarProblem statement: Wireless ADHOC networks are self organized dynamic networks can share wireless channel without any established central control standard for IEEE 802.11. Approach: The most common protocols are AODV, DSDV, DSR in ADHOC used to ensure the data transmission among themselves. To meet the need of low power and low cost IEEE 802.15.4 standard was developed for sensor networks. … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,409 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAuthentication 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 keywordsMobile Ad Hoc Network Security for Reactive Routing Protocol with Node Reputation SchemeA. Suresh, Dr. K. DuraiswamyThe mobile node’s reputation in the Mobile Ad hoc Network (MANET) identifies its trust worthiness for secured multiple data communication. Unknown nature of the node’s communication status for initial period has great impact in the effective data transfer as MANET is self-organized and distributed. Problem statement: The functional operation of the mobile network relies on the trusty cooperation between the … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 6,988 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 · 7,304 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDensity 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 accessIn the keywordsNodes 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 accessIn the keywordsAn Effective Location-Based Power Conservation Scheme for Mobile Ad Hoc NetworksKhalid Kaabneh, Azmi Halasa, Hussein Al-BahadiliProblem statement: One of the major issues in current reactive routing protocols for Mobile Ad Hoc Networks (MANETs) is the high bandwidth and power consumptions during the routing process.
