Wireless Sensor networks are dense wireless networks of small sensors, which collect and disseminate environmental data. Wireless sensors, and the arrangement of these small, electronic devices into radio networks, have introduced the capability of remotely monitoring a physical environment for a wide variety of parameters. There are many issues in wireless sensor network of concern one of them is minimizing the energy consumption in wireless sensor network and increasing the performance. There are various parameter to measure performance of system the authors have taken two parameters like packet delivery ratio and throughput to indicate performance of the network.
