    • A method of transmitting a message from a source node to a destination node in a small, wireless network having up to N nodes in which each message has appended thereto concise network configuration data which eliminates the need for routing protocols without adding significant overhead to the network communications. The method includes the steps of creating for each node a route table containing a count of the number of transmission hops necessary to reach each destination node and a node number of a neighboring node forming a next link in a chain of hops to each destination node, where the node number identifies a unique bit in an N bit address mask. Routing data is appended to the message data which includes an N bit destination word identifying the destination node or nodes, an N bit route word including a logical OR of the address mask of the relay node or nodes, and a route update message identifying what the current node knows about the network configuration. The number of N bit words in the route update message indicates a maximum number of transmission hops away from the current node that the current node could know about the network configuration. Upon receipt of such message data and its routing data, all receiving nodes update their route tables from the route update message. Then, if the receiving node is a destination node, the message data is processed. Also, if the receiving node is a relay node, then the receiving node replaces the route word and route update message with data from its updated route table and retransmits the message data with the destination word, the replaced route word and the replaced route update message as its routing data.
    • 在具有多达N个节点的小型无线网络中将消息从源节点发送到目的地节点的方法,其中每个消息已附加到其上简洁的网络配置数据,其消除了对路由协议的需要而不增加网络的显着开销 通讯。 该方法包括以下步骤:为每个节点创建包含到达每个目的地节点所需的传输跳数的计数的路由表,以及形成到每个目的地节点的跳链中的下一个链路的相邻节点的节点号, 其中节点号标识N位地址掩码中的唯一位。 将路由数据附加到消息数据,该消息数据包括标识目的地节点或节点的N位目的地字,包括中继节点或节点的地址掩码的逻辑OR的N位路由字,以及标识哪个 当前节点了解网络配置。 路由更新消息中的N位字的数量表示当前节点可以知道关于网络配置的当前节点的最大传输跳数。 在接收到这样的消息数据及其路由数据之后,所有接收节点从路由更新消息中更新它们的路由表。 然后,如果接收节点是目的地节点,则处理消息数据。 此外,如果接收节点是中继节点,则接收节点用来自其更新的路由表的数据替换路由字和路由更新消息,并用目的地字,替换的路由字和替换的路由更新消息重传消息数据 作为其路由数据。
