Risks on user applications has significantly changed in the cloud computing infrastructure because of the failures such as server overload, network congestion, hardware faults, etc. Hadoop uses a single metadata server namely NameNode (NN) which keeps the whole file system metadata in primary memory. In Hadoop, the I/O operations associated with those credential metadata makes NameNode a Single Point...
A Text-editor application which incorporates the Co-operative provable data possession scheme allows the user to upload files, request for a challenge/proof check, view the contents of the file in a secure manner and allows him/her to audit the files which he stored in the cloud. High security is guaranteed because the data of the user passes through two levels of storage. The algorithm focuses on...
This paper presents a dual voltage source inverter (DVSI) scheme for microgrid system, which enhances the power quality and reliability of the microgrid system. The scheme comprises of two inverters namely the main inverter (MVSI) and the auxiliary inverter (AVSI). The DVSI scheme enables the microgrid to exchange power generated by the distributed energy resources (DER) to the loads and in addition...
