Enhanced Passive Duplicate Address Detection (EPDAD) for Autoconfiguration in MANETs

摘要

The uniqueness of IP addresses assigned to member nodes in MANETs is confirmed with a Duplicate Address Detection (DAD) method. But DAD often faces flooding issues which is addressed with a routing integrated protocol also called as Passive Duplicate Address Detection (PDAD) schemes. Although the existing scheme proves to be beneficial in terms of route processing time and overhead in the nodes they induce high complexity during integration. The paper presents a routing integrated and proficient approach for address autoconfiguration called the Enhanced Passive Duplicate Address Detection (EPDAD). The EPDAD employs a light weight and hastier technique for DAD. The EPDAD scheme uses a Bloom filter for compact storage of stateful information and easy retrieval during DAD. So as soon as the duplicates are detected by Bloom filters, it provokes routing integrated DAD procedures. The EPDAD and an existing scheme are simulated to study the performance of the schemes. The results prove that the EPDAD scheme has minimum DAD time, route processing delay and packet losses compared to the existing scheme.
