Abstract: The Wireless Sensor Network (WSN) network is group of sensor nodes. Wireless Sensor Network (WSN) is suitable for places where connection through wireless is not possible. The network establish from cables is costly and difficult to implement as compares to Wireless Sensor Network (WSN). The Wireless Sensor Network (WSN) is Auto configured Network means if WSN goes down it will start automatically with its configuration so Wireless Sensor Network (WSN) is more suitable then network with wires and cables. While building infrastructure the energy consumption is main constrain while setting route the increase in distance in distance in Wireless Sensor Network (WSN) leads to problem for network .the multi-hop transmission routing consumes less energy as compared to direct link. The significant topology management should be done for less energy consumption network in Wireless Sensor Network (WSN) Sensor network is formed by sensor nodes and they are proficient for transmission. energy consumption is major issue in Wireless Sensor Network (WSN)the routing technique are formed for better energy efficient routing and to increase the life of network for efficient data transmission in Wireless Sensor Network (WSN) The various data dissemination protocol are used for better transmission and less energy consumption environment is maintained by different protocol in Wireless Sensor Network (WSN) The performance of existing technique PSO with v-leach is less as compared to proposed PNRD (Pre Neighbor Node Route Discover technique )provide efficient result and performance to minimizing the energy Loss and increase the network life of WSN. The comparative performance of other parameters like End-to End delay, Energy consumption and data transmitted is better as compared to existing PSO v-leach technique.
