Wireless Sensor Nodes generally have less battery life and less memory. Because of that constraint, we need a strong algorithm that allows us to reduce energy consumption as well low loss of packets. Throughout transmission of the data the energy is used for transmitting the packets. Part of the energy is utilized for data processing. We compare the Energy Consumption and Packet Loss Analysis of LEACH Routing Protocol on WSN over DTN. So we must use short-distance routing and data compression to reduce the power consumption. Using connected wireless sensor nodes a wireless sensor network is created, so each node is very compact and capable of detecting, storing, processing and communicating with other nodes within the environment. Good adaptability, good tolerance of faults and broad perception are the key advantages. Such functions enable the extension of wireless sensor networks to various applications, such as environmental monitoring, home care, medical care, and monitoring of battlefields. Recently WSNs have become a vital study area. Through wireless sensor networks more energy is used during the contact cycle between the sensor nodes. Prior the DTN do work as same as the WSN work on distributed platform. But in the term of efficiency and loss it find better ultimately have selective choice of WSN over the DTN.
