  • In the last years the Wireless Sensor Networks' (WSN) technology has been increasingly employed in various application domains. The extensive use of WSN posed new challenges in terms of both
    scalability and reliability. This paper proposes Sensor Node
    File System (SENFIS), a novel file system for sensor nodes,
    which addresses both scalability and reliability concerns. SENFIS
    can be mainly used in two broad scenarios. First, it can
    transparently be employed as a permanent storage for distributed
    TinyDB queries, in order to increase the reliability and
    scalability. Second, it can be directly used by a WSN application
    for permanent storage of data on the WSN nodes. The
    experimental section shows that SENFIS implementation makes an efficient
    use of resources in terms of energy consumption, memory
    footprint, flash wear levelling, while achieving execution times
    with existing WSN file systems.
