This paper presents a gradient routing algorithm a modified approach of DIR (compass routing) method to suit for mobile ad hoc network. It is a direction based localized algorithm where each node makes forwarding decisions solely based on the position of itself, its neighbors and destination. Source node selects a neighbor node to forward a message which is closest (having minimum gradient i.e. angle) towards the direction of destination. This algorithm makes use of the position information of nodes to improve the performance of routing protocols in mobile ad hoc network. The performance of gradient algorithms is compared with other directional routing algorithms LAR and DREAM in mobile environment using proactive approach. The experimental results show that gradient algorithm have higher success rate and lower flooding rate compared to LAR and DREAM
