Low Energy Adaptive Clustering Hierarchy (LEACH) is one of clustering routing protocols on Wireless Senosor Network (WSN). LEACH algorithm is divided to setup phase and steady state phase. In a busy network, LEACH Routing has a high packet loss. To solve the problem we need Delay Tolerant Network (DTN). DTN is an advanced architecture that allows communication in extreme conditions like a busy network. In this research, LEACH-WSN changes to optimize the network by adding DTN to LEACH-WSNoverDTN. The LEACH-WSN modification by providing a bundle layer to keep the data temporarily. Simulation is performed to test the performance of LEACH-WSNoverDTN based on changes in the number of node and buffer capacity. In changing the number of node, LEACH-WSNoverDTN can improve performance by decreasing packet loss value by 50% of LEACH-WSN packet loss. In changing of the buffer capacity, LEACH-WSNoverDTN also improves performance on PDR values that increase by 1.8% of LEACH-WSN. In the test of energy consumption in two scenarios, LEACH-WSN and LEACH-WSNoverDTN have no significant differences but when we check the lifetime of node which depends on energy consumption, LEACH-WSNoverDTN has early death node. The effect of LEACH-WSNoverDTN is significant when the number of nodes increases or busy network.
