    摘要： PROBLEM TO BE SOLVED: To solve such a problem that the loop of a packet is generated when an inter-node metric value is rapidly changed concerning a route calculation device. SOLUTION: When the inter-node metric value is changed from A n-1 to A n , it is determined whether the amount of change is within a prescribed range. When the amount is not within the range on the basis of the determination result, a correction value with the amount of change reduced therein is calculated through the use of the metric value A n-1 . Then the correction value is settled as the metric value. COPYRIGHT: (C)2011,JPO&INPIT

    解决方案：当节点间度量值从A n-1 改变为A n 时，确定变化量是否在规定范围内 。 当基于确定结果不在该范围内时，通过使用度量值A n-1 来计算其中减少了变化量的校正值。 然后将校正值确定为度量值。 版权所有（C）2011，JPO＆INPIT

    摘要： PROBLEM TO BE SOLVED: To prevent cutoff of communication when a communication path is switched over to a redundant path, and to restrain a communication band and power consumption for confirming the redundant path, in a radio multihop communication system. SOLUTION: When transmitting a data signal to a radio communication device of a transmission destination by radio multihop communication via a first route, this radio communication device transmits a signa for determining whether communication with the radio communication device of the transmission destination by radio multihop communication via a second route is possible to the radio communication device of the transmission destination by the radio multihop communication via the second route.
