The mobility metric is intended to capture and quantify the motion of mobile nodes. It is an important value to be considered in order to select a proper clusterhead for clustering. In this paper, we propose a mobility metric that is based on an area value which is evaluated by 3-waypoint for MANET. The waypoint is a collection of places where mobile nodes change in a course while they are on a long journey. In order to know the mobility metric, we calculate an area of a triangle with the sequenced waypoint of three and can estimate how far mobility of the mobile nodes is. This mobility metric is a combination of the velocity, direction and distance component of mobile nodes. Therefore, we believe in using the mobility metric results in a more stable configuration.
