Programming Wireless Sensor Networks (WSNs) is currently perceived as a difficult task, an issue which may seriously hamper a widespread adoption of this technology. Most often, WSN programmers work at the level of the operating system, using basic communication primitives. Differently, TeenyLIME empowers WSN programmers with a higher level of abstraction by replacing the OS-level communication constructs with the notion of a shared memory space spanning neighboring (1-hop) nodes. TeenyLIME can be used to implement both application-level and system-level mechanisms, e.g., routing and MAC protocols. In addition, unlike most programming models in the WSN literature, TeenyLIME is extensively used in real-world WSN deployments, e.g., monitoring of heritage buildings and adaptive lighting in road tunnels, where it provides a foundation to build efficient WSN systems with reduced programming effort.
