The performance of wireless sensor networks is severely restricted by the energy limits of the nodes. Clustering is one approach to the reduction of energy consumption since it permits data aggregation (e.g. fusion and compression) and better control of the transmit power. This paper studies the total energy consumption of the cluster approach. We assume a configuration in which nodes are deployed in a reticular pattern and all nodes can communicate with the gateway directly. We use two energy consumption models; I) a model based on a radio propagation formula (first-order radio model), and II) a model based on the existing Chipcon device CC1020. We then compare clustering to direct communication in terms of total energy consumption up to the gateway. We find that clustering based on CC1020 is not effective from the point of view of total energy consumption, whereas clustering based on first-order radio model is effective.
