MANET (Mobile Ad Hoc Networks) is a wireless network in which all movable nodes can communicate with each other without depend on a fixed infrastructure. IP address is also used in MANETs, a unique IP address should be assigned to each node. Therefore, IP address auto-configuration schemes have been developed to remove the overhead of manual configuration. Mobility is one of the reasons for partitioning of the network. When a node having unique IP address in one partition, moves into another partition, there may arise a chance of duplication of the IP address. Since, IP address has to be unique, address conflicts need to be detected through a DAD (Duplicate Address Detection) procedure. This paper mainly focused on passive DAD schemes such as LOC-SD-INT (Location Source Destination with Intermediate nodes) over DYMO routing protocol. In this paper improved accuracy of detecting address conflicts, improved detection success ratio and reduced detection delay to detect address conflicts has been achieved. Through extensive simulations using the ns-2 simulator, PDAD schemes verified and better results are achieved when compared to the PACMAN scheme. By using PDAD schemes better throughput can be obtained and hence quality of service improved. The performance evaluations and results are analyzed and verified by using NS 2 (Network Simulator 2) simulator and compared with the results of existing method PACMAN (Passive Auto Configuration for Mobile Ad Hoc Networks).
