Research ArticleOpen accessIn the author namesSecure Packet Encryption and Key Exchange System in Mobile Ad hoc NerworkSudhakar Sengan, S. Chenthur PandianProblem statement: Mobile Ad-hoc Network is infrastructureless network supported by no fixed trusted infrastructure. The packets had a chance to drop or hacked by eavesdropper during transmission. So, encryption method is required for sending and receiving packet in secret manner. Approach: In this approach, the block and key size had been increased by 256 bits. When compared to Rijndael algorithm, … …Journal of Computer Science, Vol. 8, Issue 6 · 17 Mar 2012 · 7,391 accessesView PDF Cite

Research ArticleOpen accessIn the author namesAutomatic Specification Evaluator for Effective MigrationP. Sudhakar, P. SakthivelProblem statement: Software Reengineering is an effective technique for reuse the older application in the new environment. Nowadays, Reengineering techniques are increasing in spite of many difficulties and issues arise when the older application is converted to newer one. So there is a need to enhance the new system to satisfy the user requirements and quality aspects. Approach: For this … …Journal of Computer Science, Vol. 8, Issue 6 · 14 Mar 2012 · 6,757 accessesView PDF Cite

Research ArticleOpen accessIn the author namesReengineering Legacy to Modern System with One Time Checker for Information System EvolutionP. Sudhakar, P. SakthivelProblem statement: The prime focus of Information System (IS) evolution process is the aggrandize productivity and quality of various components of the system. The evolution process is always challenging as it leads to an increase in overall complexity especially when the system changes are mostly confined to part of it. Approach: In this respect to improve efficiency and decrease complexity, … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 14 Mar 2012 · 7,270 accessesView PDF Cite

Research ArticleOpen accessIn the author namesFlow Based AlgorithmT. Karpagam, V. J. Sudhakar, N. Arunsankar, M. DhanasekaranProblem statement: Network topology design problems find application in several real life scenario. Approach: Most designs in the past either optimize for a single criterion like shortest or cost minimization or maximum flow. Results: This study discussed about solving a multi objective network topology design problem for a realistic traffic model specifically in the pipeline transportation. Here flow based algorithm … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 22 Dec 2011 · 8,484 accessesView PDF Cite

Research ArticleOpen accessIn the author namesAn Improved Lazy Release Consistency ModelChapram Sudhakar, T. RameshProblem statement: A network of workstations, viewed as a distributed shared memory system can be used to develop and test parallel algorithms. Approach: For implementing parallel algorithms on such DSMs shared memory consistency model plays a vital role. Results: However on a LAN, strict consistency models like Sequential Consistency model (SC) are not useful since the communication is slow. In … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,147 accessesView PDF Cite
