Abstract:
A method of enabling location-independent packet routing in a short-range wireless networking environment, comprising the steps of:providing one or more portable client devices, each of the client devices identified by a constant client address and equipped with a short-range wireless communications capability for communicating in the short-range wireless networking environment; providing one or more application servers, each of the application servers equipped for communicating with the client devices over the short-range wireless networking environment; transmitting a packet from a selected one of the client devices to a selected one of the application servers; receiving the transmitted packet at a Foreign Address Masquerader (FAM); accessing, by the FAM, a FAM translation record; applying, by the FAM, a network address translation to replace a client address and port in the transmitted packet with a masquerading address and port retrieved by the accessing step, thereby creating a modified packet; and forwarding, by the FAM, the modified packet to the selected application server.
