Abstract
This paper presents a methodological survey of storage mechanisms in WSN. We survey various data replication mechanisms for efficient data storage to eliminate the various challenges in WSN like energy constraint, storage space constraint, We observe that local storage, external storage have limited benefits when compared to data centric mechanisms like GHT mechanisms. Additionally we look at the data replication mechanisms to enhance fault tolerance while storage of data. The hierarchical management techniques reduce the network traffic by storing data in multilayer architectures. This paper presents the technical specifics of such architectures and how query execution happens in such systems.
