There are three approaches to disseminate queries into the sensor network, which are the multi-hop unicast, full flood and geocast. Since the energy is very limited resource of the sensor network, query optimizer must select an optimal approach consuming minimum energy to disseminate the query into the sensor network. As the selection relies on energy consumption estimation, the accuracy of the energy consumption estimation is very critical for query processing in sensor network. In this paper, a general energy consumption estimation model is proposed. Compared with other models, our model takes both routing protocol and MAC protocol into consideration. In experiments we compared our energy model’s estimation for the multi-hop unicast, full flood and geocast with simulation results. Results showed that our model’s accuracy is very high.
