Wireless Sensor Network consist of large number of sensing devices, which are equipped with limited radio communication capabilities and limited computing which is used for many purposes in the present and the future. Clustering and routing in wireless sensor networks for the transfer of information from sensor nodes to base station are especially important. Energy is one the most important items to determine the network lifetime due to low power energy nodes included in the network. For improving this major parameter the authors have to design best network architecture and consider all impact components.
