Patent ID: 8155004

Claim:
A mobile network system based on an ad hoc on-demand distance vector (AODV) routing algorithm, the system comprising: a destination node: a source node to transmit a data packet to the destination node by following a first communication path; a plurality of intermediate nodes located on the first communication path; and a mobile node not located on the first communication path to receive the data packet from each of the plurality of intermediate nodes, to check the data packet received from each of the plurality of intermediate nodes, to discard the data packets having a packet information different from the other data packets, to check hop count numbers for each of the plurality of intermediate nodes that transmitted the data packet having same packet information, and to replace at least a portion of the first communication path with a new communication path between a first node having a minimum hop count and a second node having a maximum hop count by acting as an intermediate node between the first node and the second node, wherein the hop count represents a number of intermediate nodes that are located on the first communication path between the source node and a plurality of present nodes that transmit the data packet to the mobile node when the mobile node moves into a communication range of the plurality of present nodes.
