| Abstract(in English) | Cooperative transmission can extend the transmission range by transmitting the same data from multiple wireless nodes, and consequently can reduce the consumed power of each node. In this paper, we apply the cooperative transmission to a wireless sensor network where the sensor nodes are organized into multiple clusters. To perform the cluster-based cooperative transmission, it has to choose a cluster head which broadcasts its decoded data to other nodes in a cluster. The overall dissipation power is, however, governed by the cluster head selection criterion. In this paper, we propose a simple cluster head selection criterion considering the residual power of each sensor node, and aim to extend the network lifetime. As results, the proposed scheme shows the best in the active sensor node rate and outage probability. |
