In mobile ad hoc network (MANET), the increased node mobility causes increased control overhead. The existing route discovery technique is not efficient for intermittently connected or Delay Tolerant Network (DTN). In order to overcome these issues, in this paper, we propose location aided cluster based geographical routing protocol for intermittently connected MANET. In this technique, cluster head is chosen based on node value which is estimated based on degree difference, node mobility and residual energy. The cluster consists of GPS enabled node and antenna equipped node. The cluster that contains atleast one G-Node considers the remaining energy, speed of the node along with the mobility of node to select the cluster head. Also the cluster maintenance is implemented in order to re-organize and re-configure the cluster dynamically due to the mobility of nodes in the ad hoc networks. Then a store-carry forward and geographical routing based routing protocol is employed. Finally, in order to prevent the location error caused during routing, a location update technique is executed. By simulation results, we show that proposed technique minimizes the control overhead and delay
