Energy efficient query aggregation and optimization scheme in wireless sensor network

In wireless sensor networks, the main obstacle is power limitation and memory constraint. As communication is the most power consuming task, we need to minimize both the number of communications and concise the amount of data.To achieve these goals, previous works proposed different techniques like query optimization using various heuristics ,in-network data aggregation, efficient routing , external storage with historical database. We intend to use all these mechanisms along with some novel ideas to accomplish better energy efficiency . We can infer from logical reasoning that the proposed heuristics give better performance in reducing power consumption.
