A Technique for Power-Aware Query-Informed Routing in Support of Long-Duration Queries for Sensor Networks

In-network aggregation is a useful technique to mitigate the limited power problem in sensor networks. In order to further reduce power usage, many efforts have focused on the application layer. In contrast, our work integrates the application and network layers with a focus on the generation of a routing topology for sensor networks. We present a grouping technique to construct a routing tree topology based on information contained within specific queries. This "query informed" method enables the query process to be efficient in terms of energy consumption. The technique is aimed at applications that require long-duration queries, and is described in terms of algorithmic behavior, simulation experiments, and comparative analysis to conventional techniques
