摘要： In wireless communication using links with neighbor wireless devices, a wireless device calculates ratios of throughput to maximum throughput for the links and calculates the costs of the links using the calculated ratios. Then the wireless device finds, for each destination, a route in which the sum of such calculated link costs is the minimum, and sends a packet to the destination using the route. As a consequence, routing can be done according to an isotonic, easy-to-implement routing protocol.
摘要翻译：在使用与相邻无线设备的链路的无线通信中，无线设备计算链路的吞吐量与最大吞吐量的比率，并使用所计算的比率来计算链路的成本。然后，无线设备针对每个目的地找到这样计算的链路成本的总和最小的路由，并且使用该路由向目的地发送分组。因此，可以根据等渗，易于实现的路由协议完成路由。

摘要： The route maintenance unit outputs a period setting request to the period setting unit when the communication unit normally receives a Hello packet for the first time. The period setting unit sets a link connection confirmation period in response to the period setting request and outputs the set period to the route maintenance unit. The route maintenance unit maintains a radio link between the radio device in which the route maintenance unit is provided and an adjacent device upon receiving a data packet other than a Hello packet from the adjacent radio device even if a Hello packet is not received in the link connection confirmation period. Consequently, route disconnection or switching occurs less often.
摘要翻译：当通信单元首次正常接收到Hello分组时，路由维护单元向周期设置单元输出周期设置请求。周期设定单元响应于周期设置请求设置链路连接确认周期，并将设置的周期输出到路线维护单元。路由维护单元在从邻接无线设备接收到除了Hello报文以外的数据分组的情况下，即使没有在链路中接收到Hello分组，也保持在提供路由维护单元的无线设备与相邻设备之间的无线链路连接确认期。因此，路由断开或切换较少发生。

摘要： A radio device is located far from other radio devices in a radio network system. The radio device determines a threshold WIth for detecting a strength equal to or more than the minimum strength of radio waves transmitted/received in a stable radio wave environment based on a plurality of reception signal strengths of Hello packets received from radio devices adjacent to the radio device. Then, if the number of radio devices adjacent to the radio device when the threshold WIth is introduced is less than a standard value (such as five), the radio device stores the adjacent radio devices in the neighbor list without introducing the threshold WIth, and then, maintains in the routing table the routing information of routes passing through the adjacent radio devices based on the neighbor list.

摘要： Radio devices (31 to 43) receive a prescribed number of Hello packets from each of n radio devices existing within one hop from each radio device, detects six pairs of maximum and minimum values MAX[1] and MIN[1] to MAX[6] and MIN[6] based on the plurality of reception signal strengths of the plurality of received Hello packets, detects two adjacent maximum values having the largest difference among six pairs of maximum and minimum values D_MAX[1] and D_MIN[1] to D_MAX[6] and D_MIN[6] when the six maximum values MAX[1] to MAX[6] are in descending order, and determines the average of two minimum values corresponding to the detected two maximum values as a threshold. The radio devices (31 to 43) each produce a routing table including routes having reception signal strengths equal to or more than the threshold.
