Mobile ad hoc networks (MANETs) consist of a set of mobile nodes lacking a predetermined infrastructure. Due to this dynamic nature, there exist rapid link breakages which leads to frequent path failures and simultaneous route discoveries. For improving the routing performance we propose a novel routing protocol called Enhanced Neighbor Coverage-Based Probabilistic Rebroadcast Protocol (ENCPR) for reducing routing overhead in MANETs, it propose the strong coverage condition for reducing the number of redundant transmissions. It also checks the link and path stability among nodes to allow the reduction of control overhead and it can offer some benefits also in terms of energy saving in mobile ad hoc networks. It can get hold of more precise additional coverage ratio by sensing neighbor coverage knowledge, it also identify a connectivity factor to offer the node density adaptation. By combining the additional coverage ratio and connectivity factor, it put a sensible rebroadcast probability. This approach combines the advantages of the neighbor coverage knowledge and the probabilistic mechanism, which can drastically diminish the number of retransmissions so as to reduce the routing overhead, and can also improve the routing performance.
