An Energy Efficient Data Query Architecture for Large Scale Sensor Network

With the advance of micro-electronic and wireless communication technology, deploying a large number of low cost, small-sized sensor nodes over a vast area for environment detection is becoming more practical. Setting up gradients for delivering queries or data reports by flooding the networks consumes a great quantity of energy especially for a large scale sensor networks. In this paper, we propose an energy efficient data query architecture. It conserves energy by avoiding full network flooding in setting up data forwarding path. Simulations show that the proposed architecture is quite energy efficient.
