In most research work for sensor network routings, perfect aggregation has been assumed. Such an assumption might limit the application of the wireless sensor networks. We address the impact of aggregation efficiency on energy consumption in the context of GIT routing. Our question is the extent to which energy consumption can decrease compared to the original GIT. In this paper, we propose an improved GIT: "aggregation efficiency-aware routing", or AGIT. We also consider two suppression schemes for exploratory messages: "minimum exploratory" and "hop exploratory." Our simulation results show that the AGIT saves the energy consumption of the data transmission compared to the original GIT.
