Patent ID: 7092391

Claim:
A method for performing multi-hop peer-to-peer telecommunications on a wireless network, which includes a plurality of radio terminals that can conduct mutual communication within a prescribed covered area, and topology of which can change moment by moment, comprising the steps in which: each radio terminal exchanges a link state with other radio terminals within said prescribed covered area, and constructs a routing table based on the exchanged link state; a source routing demand packet is prepared including a routing stack for storing intermediate routing information therefor whenever said source routing demand packet passes through the terminals; a sender terminal includes identification information on a destination terminal in said source routing demand packet and broadcasts said source routing demand packet; the radio terminals on a route of said source routing demand packet write the intermediate routing information to said routing stack while multicasting said source routing demand packet to all radio terminals within said prescribed covered area based on said routing table; the destination terminal which receives said source routing demand packet unicasts said source routing demand packet to said sender terminal through the route followed by said source routing demand packet based on information in said routing stack included in said source routing demand packet; and said sender terminal, which receives said source routing demand packet unicasted by said destination terminal, unicasts a message to said destination terminal through the radio terminals on said route followed by said source routing demand packet based on information in said routing stack included in said source routing demand packet.
