A power efficient scheduling scheme extending the life time of sensor nodes on wireless sensor networks has been proposed in this paper. This power efficient sleep scheduling algorithm is based on the connected dominating set approach. This approach first constructs a connected dominating set for parent selection and uses the conjugative sleep scheduler scheme for data aggregation. The re-calculation of connected dominating set when the node is in ON condition and in OFF conditions have been discussed. Finally, the performance of connected dominating set approach is compared with minimum spanning tree approach.
