TeenyLIME: Transiently Shared Tuple Space Middleware for Wireless Sensor Networks

Recent developments in wireless sensor networks (WSNs) are push- ing scenarios where application intelligence is no longer relegated to the fringes of the system (i.e., on a data sink running on a powerful node) rather it is distributed within the WSN itself. To support this scenario, we propose TeenyLIME, a tuple space model and middleware supporting applications where sensing and acting devices themselves drive the network behavior. In other words, the application core is not confined to the powerful sinks, rather it is deployed on the devices embedded within the physical world. Tuple space operations are used both for data collection as well as to effect coordination among sensing and acting devices. This paper describes the TeenyLIME model and corresponding middleware implementation.
