Several projects in the recent past have aimed at promoting Wireless Sensor Networks as an infrastruc- ture technology, where several independent users can submit applications that execute concurrently across the network. Concurrent multiple applications cause significant energy- usage overhead on sensor nodes, that cannot be eliminated by traditional schemes optimized for single-application scenarios. In this paper, we outline two main optimization techniques for reducing power consumption across applications. First, we describe a compiler based approach that identifies re- dundant sensing requests across applications and eliminates those. Second, we cluster the radio transmissions together by concatenating packets from independent applications based on Rate-Harmonized Scheduling.
