Techniques are described herein to refine Personal Area Network (PAN) migration processes and shorten offline duration using various mechanisms, including: 1) performing a re-authentication and key exchange with a target PAN's Field Area Router (FAR) over a current PAN's FAR while performing migration between the two PANs; 2) eliminating a re-authentication process by sharing the same pairwise master key (PMK) for one node between all FARs in one service set; 3) synchronizing with a target PAN over current PAN's FAR, which can be quicker than synchronization over the air; and 4) eliminating Dynamic Host Configuration Protocol (DHCP) version 6 (DHCPv6) processes, keep a global Internet Protocol version 6 (IPv6) address unchanged, and creating a downward route adaptively while performing migration between the two PANs. Using these mechanisms, a node will be able to migrate between various PANs more quickly and the service interruption gap will be much shorter.
