Three of the basic discussions in wireless sensor networks are routing, information exchange and lack of energy hole problem in network nodes. Considering the limitation of energy resources in these networks, the selection of an appropriate clustering method , clustering environment and proper routing has a tremendous effect on improving the efficiency of the network. Energy Hole in wireless sensor networks due to energy discharging of the nodes which are close to sink are caused because of sending its information and the further clusters from these nodes to the sink. In this article we will try to offer a method for solving this problem. By mixing some methods and utilizing of a new method. At first we will divide the network into concentric circles and each of these circles will be a layer. Then the circles will be divided into four equal parts from the largest circle. In the next step the first layer will be selected lager than the other layers and smaller than radio board and a number of sensor nodes will be placed in this layer, to reduce the extra charge from these sensors. In the next stages the life time of the network will be increased by appropriate directing and classifying to restrict of initiating energy hole.
