In this paper, it proposes mobility based dynamic reconfiguration system in WSN. By providing access for the user to construct different virtual fields, proposed protocol accomplishes the goal of meeting the need of different applications and different network conditions. In this paper, an environmental data collection scenario is taken. In this, all nodes are in dynamic nature and moves randomly. Sensor nodes are prone to failure due to energy depletion and their deployment in an uncontrolled or even hostile environment, also providing a convenient method for the administrator of the WSN to reconfigure the system just by a remote application. It can achieve the goal that adopt to different applications and different network conditions. This protocol will give the administrator of the WSN a powerful ability.
