Abstract
According to an embodiment, a communication system includes a plurality of nodes that forms a wireless multi-hop network. One of the nodes includes a processor and a wireless communication controller. When receiving a packet including path information that indicates a parent-child relationship of transfer nodes included on a network topology from a source node to a destination node, the processor is configured to determine whether or not at least one of its own node and a neighboring node existing near the own node is included in the path information as the transfer node. When at least one of the own node and the neighboring node is included in the path information, the wireless communication controller is configured to transfer the packet.
Claims9
A communication system comprising:
- a plurality of nodes that forms a wireless multi-hop network, one of the nodes comprising:
- a processor configured to determine, when receiving a packet including path information that indicates a parent-child relationship of transfer nodes included on a network topology from a source node to a destination node, whether or not at least one of its own node and a neighboring node existing near the own node is included in the path information as the transfer node;
- and
- a wireless communication controller configured to transfer the packet when at least one of the own node and the neighboring node is included in the path information.
A node comprising:
- a processor configured to determine, when receiving a packet including path information that indicates a parent-child relationship of transfer nodes included on a network topology from a source node to a destination node, whether or not at least one of its own node and a neighboring node existing near the own node is included in the path information as the transfer node;
- and
- a wireless communication controller configured to transfer the packet when at least one of the own node and the neighboring node is included in the path information.
A computer program product for a plurality of nodes that forms a wireless multi-hop network, the computer program product comprising a non-transitory computer-readable medium including programmed instructions, the instructions causing a computer of one of the nodes to execute:
- determining, when receiving a packet including path information that indicates a parent-child relationship of transfer nodes included on a network topology from a source node to a destination node, whether or not at least one of its own node and a neighboring node existing near the own node is included in the path information as the transfer node;
- and
- transferring the packet when at least one of the own node and the neighboring node is included in the path information.
