    • PROBLEM TO BE SOLVED: To provide a communication device that obtains metric information including information on an available time slot, calculates a communication cost, and selects an appropriate route in a mesh network employing a time division multiplexing communication system.SOLUTION: A communication device 10 forms a sub-network which is a part of a mesh network employing a time division multiplexing communication system, selects an appropriate communication route from a plurality of communication routes to another communication device formed by reserving a time slot, and communicates through it. The communication device 10 includes: information acquisition means 31 which acquires information to be used for communication route selection from a radio communication relay device on the reserved communication routes; and route selection means 34 which selects an appropriate communication route from the reserved communication routes using the information to be used for the communication route selection. The information to be used for the communication route selection includes time slot information allocated to the radio communication relay device. The route selection means selects a communication route on which delay is less based on the time slot information.
    • 要解决的问题:提供一种通信装置,其获得包括关于可用时隙的信息的度量信息,计算通信成本,并且在采用时分复用通信系统的网状网络中选择适当的路由。 解决方案:通信设备10形成作为采用时分复用通信系统的网状网络的一部分的子网络,从多个通信路由中选择适当的通信路由到通过保留时间而形成的另一通信设备 插槽,并通过它进行通信。 通信设备10包括:信息获取装置31,其在预留的通信路由上从无线电通信中继装置获取用于通信路由选择的信息; 以及路由选择装置34,其使用要用于通信路由选择的信息从保留的通信路由中选择适当的通信路由。 用于通信路由选择的信息包括分配给无线电通信中继设备的时隙信息。 路由选择装置根据时隙信息选择延迟较小的通信路由。 版权所有(C)2013,JPO&INPIT
