Wireless sensor networks operate under the control of power where power is related to the battery. Network topologies will have impact on network properties like energy consumption. Energy efficiency can be improved by improving the lifetime of battery of the sensor nodes. For that, topology also plays a vital role. Researchers put various efforts on finding a best topology for wireless sensor network with high efficiency. In this paper different topologies of wireless senor network are studied and a new topology is proposed. The simulation result shows that the proposed topology is highly efficient than the existing ones.
