Patent ID: 7633884

Claim:
An address allocation method using site-local prefix pools, comprising: generating link-local addresses by a plurality of nodes participating in a network, and performing Duplicate Address Detection (DAD) to guarantee the uniqueness of the link-local addresses; electing a leader node of the plurality of nodes which notifies the remaining plurality of nodes of a site-local prefix of the network; deciding whether neighboring networks adjacent to the network exist; generating a site-local prefix pool comprising a plurality of site-local prefixes at random if the neighboring networks do not exist; selecting one site-local prefix from the site-local prefix pool, and allocating the one site-local prefix to the network; and notifying the remaining plurality of nodes of the one site-local prefix allocated by the leader node in order for each of the remaining plurality of plural nodes to generate a site-local address, and further comprising when the neighboring networks exist, acquiring by the leader node a second site-local prefix pool including at least one site-local prefix from the neighboring networks, the network being a mobile ad-hoc network.
