Decrease energy consumption and maximizing network lifetime are important parameters in designing and protocols for Wireless Sensor Network (WSN). Clustering is one of the efficient methods in energy consumption by Cluster-Head in WSN. Besides, CH can process and aggregate data sent by cluster members, thus reducing network traffic for sending data to sink. In this paper presents a new cluster routing algorithm by dividing network into grids. In each grid computes the center-gravity and threshold of energy for selecting the node that has the best condition base on these parameters in grid for selecting Cluster-Head in current round, also SLGC selecting Cluster-Heads for next rounds thereby this CHs reduced volume of controlling messages for next rounds and inform nodes for sending data into CH of respective round.
