In this paper, we propose X-Tree Programming, a novel database-centric programming model for wide-area sensor systems designed to achieve the seemingly conflicting goals of expressiveness, ease of programming, and efficient distributed execution. To demonstrate the effectiveness of X-Tree Programming in achieving these goals, we have incorporated the model into IrisNet, a shared infrastructure for wide-area sensing, and developed three widely different applications, including a distributed infrastructure monitor running on 473 machines worldwide.}, url = {http://approjects.co.za/?big=en-us/research/publication/database-centric-programming-for-wide-area-sensor-systems/}, edition = {DCOSS'05: First International Conference on Distributed Computing in Sensor Systems}, }
