【Abstract】 An algorithm which can tolerate the failure of nodes and time synchronization is proposed in this paper,which is termed as ICSS (Intra-Cluster Sleeping scheduling). The algorithm does not require external precise synchronization mechanism. It gives different scheduling mechanisms for different types of nodes,and considers the failure and update of synchronization. The simulation results show that in the dense deployment networks,the algorithm meet the transmission performance and increase the node lifetime 16.7% and 10.5% respectively compared to the fixed time-interval scheduling without synchronization and the fixed time-interval scheduling with synchronization.更多还原
