Abstract: A method for routing a packet of information between two hosts that are coupled to a network. Each of the hosts have a unique network address, and at least one of the hosts is a mobile host (10) that does not have a fixed network coupling location. The method includes a first step of (a) transmitting a packet from the mobile host to a second, destination host on the network through a wireless link that is established between the mobile host and a base access station (12) that serves a current physical location of the mobile host. The base access station is coupled to the network via a subnetwork (LAN) (14), and the packet includes a first Internet Protocol (IP) Loose Source Routing (LSR) option that includes a network address of the base access station. A second step (b) receives with the destination host the packet that includes the first IP LSR option.
