The ease of deployment and the low cost of static ad-hoc wireless sensor networks, make them an ideal infrastructure of choice for various monitoring applications. The flexibility of expressing meaningful queries in terms of user-defined regions form an important goal of any such monitoring and query framework. Towards efficient implementation of that goal, we emphasize upon the need for supporting application-defined regions, in contrast to network driven automatic cluster-formations (either flat or hierarchical - which are typically query-agnostic).
