This paper proposes a novel data gathering scheme for Wireless Sensor Networks (WSN) that limits the energy expenditure, and hence, prolongs network lifetime. Data gathering is modeled as an auction where a node broadcasts its own result only if it is higher than the maximum already-broadcasted result by other nodes. For a WSN of 100 nodes, mathematical and simulation results show that the proposed scheme can save up to 70% of the energy consumption with less than 1% performance loss, compared to the conventional scheme.
