Delay tolerant networks are used in the areas where the network connectivity is sparse as well as the delay is very high that is in communication challenged areas. The electronic devices used in such areas will be lacking continuous power supply and thereby mostly battery powered. So there may be circumstances where, the data transmitted to an intermediate node, and the node before forwarding the data may run out of battery life. Another circumstance that may arise is that the getting lost due to any physical damage to thee node. The paper addresses simple techniques to avoid data transfer to nodes with low battery and to share data with those nodes with sufficient battery power so as to prevent any data loss and to identify any bulk packet loss due to any above mentioned issues and to efficiently route the packets. The simulation is done in ONE simulator and results are being analysed in terms of throughput ratio for different buffer size, the results show a gradual increase in throughput by the method.
