Abstract
Active packets are utilized by a mobile terminal in a wireless network to manage the micro-mobility which includes both link layer mobility and intra-domain mobility of a wireless connection as the mobile terminal moves from one cell to another in a domain of a network. Active packets convey instructions and data so nodes in the domain may update forwarding tables maintained by each of the devices in the domain. The forwarding table entries contain both link layer entries and network layer entries to efficiently handle roaming by the mobile terminal.
