Abstract
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 similarly with existing WSN file systems
