An Adaptive Approach to Alleviate Broadcasting Redundancy in MANET Address Autoconfiguration Protocols

Scalability is a major research topic in the development of MANET routing algorithms. The network resource of a mobile ad hoc network (MANET) is limited, due to the contention-based wireless communication channel. Instead of using the conventional blind flooding in AAPs, this paper proposes to adopt a dominant pruning (DP) algorithm to reduce the broadcasting redundancy in MANET address autoconfiguration protocol (AAP). A novel method to enable AAP to enhance routing capability by suggesting new messages is proposed. Simulation demonstrates that performance improves when the conventional AAPs, such as strong DAD, weak duplicate address detection (DAD) with proactive routing protocols (WDP), weak DAD with on demand routing protocols (WDO) and MANETconf, are replaced by the proposed algorithms.
