摘要： A wireless communication system provides high reliability wireless communications even when large scale interference affecting the entire system has occurred in ad hoc wireless communication systems. The node, access point, and intermediate nodes are each equipped with multiple wireless standards, and notify a wireless communication control device called a coordinator that sets the network communication paths with communication path information obtained by measuring the state of communication paths in the vicinity of their own respective nodes. The coordinator that now knows the communication status, issues instructions for setting plural routes using multiple wireless standards between the node and the access points as well as which wireless standard to use to implement communications between each intermediate zone, and each intermediate node conveys the measurement data while complying with those instructions.

摘要： In an ad-hoc wireless communication system, when there occurs a disparity in the remaining amounts of the batteries of wireless routers, it is impossible for each wireless router to change a communication route by itself. As proposed herein, in an invented multi-hop wireless network for communication via a plurality of routers, a wireless router operating intermittently changes its intermittent operation interval depending on its circumstances by its own judgment.
