Routing in Mobile Ad-hoc Networks (MANETs) is a very challenging task since, nodes are mobile and links are frequently created and broken.Traditional proactive routing algorithms initiate path discovery process from beginning after link failure occurrence.Generally, link failure occurs due to frequent topology change, fading, multiuser interference, etc., In MANETs link stability is the important criterion for link failure.Once the link meets with failure, it affects the overall performance of MANETs topology and it is very difficult to select optimum path as it leads to more transmission delay.The objective of this paper is to develop a mathematical model for Path Selection Algorithm based on Hamming Distance and delay parameters (PSA-HD).In this paper, link failure is identified, stable link is selected from the available links to reach the destination and it determines a stable path.The simulation result reveals that there is a decrease in average End-to-End delay and increase in Packet Delivery Ratio (PDR).
