摘要：In wireless sensor network most of the devices operate on batteries. These devices or nodes have limited amount of initial energy that are consumed at different rates, depending on the power level and intended receiver. In sleep scheduling algorithms most of the nodes are put to sleep to conserve energy and increase network life time . There are to main approaches to sleep scheduling i) random ii) synchronized. Main purpose of any sleep scheduling algorithm is to maintain network connectivity. In this paper, a novel approach for sleep scheduling of sensor nodes using a tree and an energy aware routing protocol which is integrated with the proposed sleep scheduling scheme. The tree is rooted at the sink node .The tree is periodically reconstructed considering the remaining energy of each node with a view to balance energy consumption of nodes, and remove any failed nodes from the tree. The proposed approach also considerably reduces average energy consumption rate of each node as we are able to put more number of nodes to sleep in comparison to other approaches such as GSP, which incorporates sleep scheduling using random approach
