Abstract: PROBLEM TO BE SOLVED: To provide a method of detecting format of received information without the use of TFCI. SOLUTION: The method is used to detects the format of the received information by measuring the time period during which information being received have a power that is at or above a defined threshold. The measured time period and the information rate of the received information are used to determine an estimate information size value of the received information. Then, the estimated information size value is applied to an algorithm that determines the format of the received information. Therefore, the format of the received information can be detected without the use of TFCI information.

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.

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 method of detecting the format of received information without requiring to use TFCI. SOLUTION: The method detects the format of the received information by detecting the format of the guide channel of a communication system. The format of the other channel of the communication system is determined by using the format of the detected guide channel by utilizing a lookup table or another mapping technique. Consequently, it is possible to detect the format of the received information without requiring to use TFCI information. COPYRIGHT: (C)2003,JPO

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: In an ad-hoc mobile network, a geometry-based routing protocol (GRP) is used to route traffic from a source node to a destination node. In order for GRP to be effective, the network needs to have certain routability characteristics. To that end, each node collects location information from surrounding nodes and uses the collected location information to select those surrounding nodes that facilitate geometric routing and sets up point-to-point links with the selected nodes (becoming direct neighbors). Th e node then constructs its k-neighborhood, (where the value of k represents the maximum number of hops needed to reach any node in the desired local topology) by exchanging i ts list of direct neighbor nodes with other nodes.

Abstract: In an ad-hoc mobile network, a geometry-based routing algorithm (GRA) is us ed to route traffic from a source node to a destination node. In the GRA, a source node maintains location information and routing information for all nodes in a local area and approximate location information for at least some nodes outside the local area. If the source node has to send a packet to a destination node outside their local area, then the source node uses the approximate location information of the destination nod e to identify which node in its local area is closer to the destination node than the sour ce node. The source node then sends the packet to the identified local node for further routing.

Abstract: In an ad-hoc mobile network, a geometry-based routing protocol (GRP) is used to route traffic from a source node to a destination node. In the GRP, each nod e maintains a location list, which comprises location information for a number of nodes of the ad-hoc mobile network. Periodically, each node transmits to its direct neighbors (i.e., those nodes with which it has a point-to-point link)(a) its location, and (b) its locati on list. Each node that receives a location list from an adjacent node merges the received location list into its own location list such that location information for existing nodes, and/or newly identified nodes, is current.
