Communication method, communication system, node, and program

A communication method, wherein a node having received a route control message transmits the route control message to a neighboring node having transmitted said route control message, and at least one neighboring node or more on an alternate route.

A communication system that is configure of at least one node or more, wherein said node comprises:

• a storage unit that stores alternate routes;
• and
• a route control message transmission unit that receives a route control message, selects at least one alternate route or more from among the alternate routes stored in said storage unit, and transmits the route control message to the neighboring nodes on the selected alternate route, and the neighboring node having transmitted said route control message.

A node, comprising:

• a storage unit that stores alternate routes;
• and
• a route control message transmission unit that receives a route control message, selects at least one alternate route or more from among the alternate routes stored in said storage unit, and transmits the route control message to neighboring nodes on the selected alternate route, and the neighboring node having transmitted said route control message.

A computer readable storage medium storing computer instructions for causing a computer executing the instructions, said instructions causing said computer to implement a method comprising:

• an alternate route selection process of, when receiving a route control message, selecting at least one alternate route or more from among alternate routes stored in a storage unit;
• and
• a route control message transmission process of transmitting the route control message to neighboring nodes on the selected alternate route, and the neighboring node having transmitted said route control message.

A communication method, wherein a node having received a cancel route information transmits arrivable route information to a neighboring node having transmitted the cancel route information.

A node, comprising a means for, when receiving a cancel route information, transmitting arrivable route information to a neighboring node having transmitted the cancel route information.
