摘要： In a communications apparatus, a communication controller transmits and receives signals on any of plural channels. A channel switching controller is responsive to channel switching information selectively defining plural reception-waiting periods using the channels to alter a channel to be used by the communication controller. A neighboring node channel controller exchanges channel switching information with other nodes to manage the channel switching information received from the other nodes. When transmitting transmission signals, a transmission controller refers to the channel switching information of the other nodes, and controls repetitive transmission of the transmission signals on the channel thus searched for.

摘要： A packet is transmitted from a source node to a destination node via a relay path in a multi-hop network. The packet is transmitted by cache routing or source routing, depending on the presence or absence of information identifying the destination node in a history table maintained at the source node. In source routing, relay path information is included in the packet. In cache routing, relay nodes obtain routing information from entries in their own cache routing tables. Each entry indicates only the destination node and the next relay node, and each cache routing table has a limited size. When a series of packets are transmitted to the second node, cache routing can be used for all but the first packet, thereby reducing packet overhead.
摘要翻译：经由多跳网络中的中继路径，从源节点向目的地节点发送分组。该数据包是通过高速缓存路由或源路由发送的，具体取决于在源节点上维护的历史表中是否存在标识目标节点的信息。在源路由中，包中包含中继路径信息。在缓存路由中，中继节点从自己的缓存路由表中的条目获取路由信息。每个条目仅指示目的地节点和下一个中继节点，并且每个高速缓存路由表具有有限的大小。当一系列数据包被发送到第二个节点时，除了第一个数据包之外，高速缓存路由可以被用于所有数据包，从而减少数据包开销。

摘要： A wireless communication system includes a first node, multiple second nodes, and multiple third nodes that communicate with the first node through the second nodes. The second and third nodes transmit control information to their neighboring third nodes, which calculate link costs from the reception status of the control information. The control information transmitted by each node includes a path cost indicating the cost of a path between the transmitting node and the first node. From the path costs in received control information, each third node selects a second node through which to communicate with the first node, and selects a parent node as the destination of the first hop on the path through the selected second node to the first node. Routing is thereby accomplished autonomously without having the second nodes flood the system with routing requests.

摘要： A tree topology in a multi-hop wireless network is configured by having each node other than the root node select a parent node within direct communication range, thereby becoming a child node of the selected parent node. Neighboring nodes provide selection values such as routing costs and local structural information indicating the existing topology in their vicinities, including parent-child relationships. The selection of the parent node is based on the received selection values, but the local structural information is used to bias the selection in favor of neighboring nodes with at least one other child node. This selection strategy reduces the number of parent nodes in the network and enables more nodes to operate as end nodes, which can then conserve power by carrying out sleep control.

摘要： In a wireless communication network system performing multi-hop wireless communications, a network node has a calculator for exchanging control packets with its neighboring nodes to calculate link cost values, another calculator for calculating path costs incurred on the way to a network node of interest, a manager for managing the number of downstream nodes subsidiary to each daughter node, and a downstream node adjuster for adjusting the number of the downstream nodes subsidiary to each daughter node. The adjuster produces control information, into which link cost and/or path cost information is inserted. The adjuster adjusts the contents of the link cost or path cost information, to be inserted into the produced control information, according to the numbers of the downstream nodes subsidiary to the daughter nodes.
