The security and availability of business data has been become most important requirement in this time. For solving the problem related to business database services like storage, security, stability, load, scalability and many other issues cloud based database platform were used. Services related to data were put on the cloud and the powerful operating systems and platform were used to process the data. This survey paper describe the different methods and architecture of cloud storage and present the disaster recovery based on the cloud computing.

This sensed data can only be of use if we know the exact position of the sensor node. This is not always easy as in many real life scenario, the deployment is random and in hostile conditions. Further, replacing a dead or damaged node is not an option in many circumstances. Many different approaches have been proposed by research community for localization information of a node deployed in a target area. In this work, an attempt has been made to review most promising localization methods proposed so far in comparative manner.
