Research ArticleOpen accessEvery word in the titleAN EFFICIENT AND VARIABLE INTERVAL REKEYING FOR DYNAMIC AD HOC MULTICAST GROUP USING KEY PATH REDUCTIONR. Pugalenthi, T. V. GopalKey distribution is one of the major issues in secure ad hoc multicast group communication. There has been an extensive research on rekeying, to reduce cost. In this study, we propose an efficient and scalable batch rekeying for dynamic ad hoc multicast group, with variable interval and key path reduction techniques. The proposed scheme overcomes the major existing issues like … …Journal of Computer Science, Vol. 10, Issue 7 · 16 Jun 2014 · 6,712 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Reconfiguration of IP Domain Middleware Stacks to Support Multicast Multimedia Distribution in a Heterogeneous EnvironmentKevin Curran, Gerard ParrSeamless connectivity to multiple wireless networks independently of a fixed point is becoming increasingly important for mobile devices however wireless networks differ in bandwidth, size and access costs each requiring protocol functions to enable devices to communicate efficiently. In addition, due to the divergence of users and applications, traditional stacks are frequently enriched with additional functionality such as transport protocol … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,781 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleServer Optimization Using Heuristic Algorithms for Dynamic-Split-and-Merge Scheme in Wireless MulticastR. Sukumar, V. VasudevanProblem statement: In order to minimize the overall network traffic in a multiserver system, the number of users served by each server (and hence the group size) should remain constant. As the underlying traffic fluctuates, a split and merge scheme is implemented in a physical server to achieve load balancing. Approach: Minimizing the number of servers during the merge operation … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 6,811 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGROUP MANAGEMENT IN MOBILE ADHOC NETWORKSK. Senthil Kumar, S. Sasi Kumar, C. SugapriyaIn this study, we proposed an algorithm for Cluster Based Zone Allocation method (CBZA) for energy conservation and packet dropping in mobile ad hoc network. MANET is a self-organized, temporarily dynamic network and their nodes are mobile without using any infrastructure. However, secure communication occurs between group nodes based on cluster method. In multicast routing, group information is shared by … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 22 Apr 2014 · 6,321 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance Evaluation of Multicrypt Encryption MechanismRhymend Uthariaraj Vaidyanathan, Lydia Elizabeth Benjamin, John Prakash ArockiasamyMulticast communication allows a single message packet to be routed to multiple nodes simultaneously. Membership in a multicast group is dynamic, allowing nodes to enter and leave the multicast session. Besides the benefits, multicast communication presents the challenge of securing the communication. In order to preserve confidentiality the general encryption mechanism used for point to point communications are used. A … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 4 Sep 2012 · 7,168 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIncorporating Multiple Sources into AMTree ProtocolAli M. Al-Sharafi, Mohamed Othman, Md. N. Sulaiman, Shamala SubramaniamAMTree protocol is an active network based protocol that makes sending packets to receivers-after source migration-an efficient process. AMTree protocol was designed and tested for one mobile source sending to the multicast group. In this research we introduce a method that allows more than one mobile source to send to the multicast session. The results show that end-to-end latencies are … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 6,870 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGroup Re-keying Protocol Based on Modular Polynomial Arithmetic Over Galois Field GF(2n)Sundaram Sudha, Azman Samsudin, Mohammad Ahmad AliaProblem statement: In this study we propose a group re-keying protocol based on modular polynomial arithmetic over Galois Field GF(2n). Common secure group communications requires encryption/decryption for group re-keying process, especially when a group member is leaving the group. Approach: This study proposes secret keys multiplication protocol based on modular polynomial arithmetic (SKMP), which eliminates the need for the encryption/decryption … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,165 accessesView PDFCite
Research ArticleOpen accessIn the abstractOPTIMIZING BATCH REKEYING INTERVAL FOR SECURE GROUP COMMUNICATION BASED ON QUEUING MODELA. Vasanthi, T. PurusothamanRapid growth of Internet spawns many group oriented multicast applications like Internet pay TV, news dissemination and stock quote system. The fortes of these applications are the support of dynamic, scalable group membership and group members are geographically divergent. As members of the group move in and out, an imperative cryptographic rekeying model should be applied to preserve the confidentiality … …Journal of Computer Science, Vol. 10, Issue 2 · 20 Nov 2013 · 6,456 accessesView PDFCite
Research ArticleOpen accessIn the abstractRouting Based Data Security in Mobile Ad Hoc Network Using Group Key ManagementE. Mohanraj, K. DuraiswamyProblem statement: A mobile ad-hoc network (MANET) is a self-organizing system of mobile devices followed an infrastructure less framework associated by wireless links. In MANET, there is a possibility of packet data to get lost or hacked by an attacker. So, to improve a secure communication over MANET from attackers, several techniques have been developed. The previous work developed to … …Journal of Computer Science, Vol. 8, Issue 10 · 29 Aug 2012 · 6,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Aware Multiple Constraints Quality of Service Routing Protocol with Dynamic Mobility Prediction for Mobile Ad hoc NetworksSenthilkumar Maruthamuthu, Somasundaram SankaralingamProblem statement: This study presents a source based reactive protocol called "Energy Aware Multiple Constraints QoS Routing Protocol with Dynamic Mobility Prediction (EMQRPDM)" for MANET. It is an enhanced version of our previous protocol called "Power aware multiple QoS constraints routing protocol with mobility prediction (PMQRPMP)". It addresses the issues such as routing, mobility and power management in MANET. Approach: … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,477 accessesView PDFCite
