Consensus: a system study of monitoring applications for wireless sensor networks

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).
