Abstract: PROBLEM TO BE SOLVED: To provide a novel routing protocol on an ad hoc network. SOLUTION: In this method, a source node collects position information from peripheral nodes, selects any one of peripheral nodes to perform geographical routing while using this selected position information and sets an inter-point link with this selected node (to become an adjacent node). Afterwards, the source node constructs almost (k) times (the value of (k) is the number of times of hopping to reach any node inside the desired local topology in this case) by exchanging the adjacent node list with the other nodes.

Abstract: PROBLEM TO BE SOLVED: To provide a new routing protocol of Ad-Hoc network. SOLUTION: In this method, a source node holds the position information, routing information of all nodes inside a local node topology and the rough position information of partial nodes outside the local topology. When it is necessary for the source node to transmit a packet to a destination node inside the local topology, the routing information is already provided. When it is necessary for the source node to transmit a packet to a destination node outside the local topology, however, which node inside the local topology is closest to the destination node is specified while using the rough position information of the destination node. When this specified node is not the source node, the source node transmits the packet to the specified node and transmits the packet to the destination node later. In the other case, the packet is dropped.

Abstract: PROBLEM TO BE SOLVED: To provide a method which uses a geography-based routing protocol GRP to perform traffic routing from a source node to a destination node in an ad hoc network. SOLUTION: Each node holds a position list in GRP, and this position list includes position information of plural nodes in the network. Each node periodically transmits the position and the position list to adjacent nodes. When receiving the position list from the adjacent node, each node combines the received position list and its own position list to update position information of existing nodes.
