AROD: An address autoconfiguration with address reservation and optimistic duplicated address detection for mobile ad hoc networks

Every node must configure its network interface with a unique address in order to communicate with other nodes. If a centralized DHCP server exists, it would easily and automatically provide addresses to nodes in a network. However, in a mobile ad hoc network, difficulties exist in supporting address autoconfiguration due to the lack of centralized servers. Therefore, we propose a distributed address autoconfiguration approach for a mobile ad hoc network using address reservation and optimistic duplicated address detection. The reserved address helps to reduce allocation latency, and the optimistic DAD guarantees the uniqueness of addresses with smaller communication overhead. Through our simulation study, we show that AROD guarantees the uniqueness of allocated addresses and considerably improves allocation latency and communication overheads.
