Abstract. In this paper, we propose algorithm to maintain the connectivity of a MANET nodes by suitably selecting `Coordinator` among the nodes constituting the MANET. The basic philosophy behind the algorithm is to select `Coordinator` amongst the system based on positional data and its energy level. Once elected, the `Coordinator` is entrusted with the responsibility to control the movement of all other nodes. All the nodes transmit their positional information obtained through GPS and energy level periodically. After analyzing the data obtained from all other nodes, the `Coordinator` directs all other nodes to control movement to keep the connectivity intact. The algorithm is going to be formulated in such a way, that the entire network is going to move in one direction. Both the `Coordinator` election and the movement algorithm is fuzzy logic based. We have simulated the algorithm in a number of synthetically designed situations and the results obtained through simulation prove the effectiveness of the algorithm.
