Objectives: To improve routing mechanism of AODV protocol to enhance performance of Mobile Ad hoc network getting congested areas. Methods/Statistical Analysis: Proposing a method to estimate the link delay at MAC layer based on service time. This method includes estimations of frame error rate and channel utilization; Using cross-layer approach to get value of link delay estimated at MAC layer. This delay is utilized to calculate delay of route at Network layer; Using route delay as the routing metric in routing process. Findings: The simulation result of AODV and the proposed protocol AODV-DM in NS2 simulation shows that AODV-DM protocol archives better performance than AODV protocol in terms of 30% higher of packet delivery ratio, 27% higher of average throughput, 32% lower of average packet delay and 40% lower of routing overhead. Application/ Improvements: The proposed AODV-DM protocol can be used in low performance Mobile Ad hoc Network due to congestion.
