网络连接

In the sparse mobile ad-hoc networks, the distance between nodes is probable larger than the normal communication range, for that reason, the disconnected or discontinuously connected network frequently come out.

在稀疏节点的移动ad-hoc网络中，由于节点之间的距离很可能大于正常通信范围，使得网络无法连接或者断续性连接情况频繁出现。

Bring forward a kind of learning algorithm fitting on the base of spline function, because the spline function has good flexibility and quadratic smoothing property, the search problem of network weight functions training can be converted into the resoluting extreme value problem of the plurality function through using spline function to represent network input and link weight functions, thus the PNN can be trained with the help of the existing neural network learning algorithms;④build a kind of learning algorithm base on the alternate of Walsh function, the complexity of network computing can be decreased through using the complete orthogonality of Walsh function corollary.

We present a SNMP-based topology discovery algorithm using direct connection theorem and simple connection theorem for judging relationship of switches in subnets. In order to in discover the map of network without SNMP, several key problems such as subnet guessing and multi-address routers are discussed in details. And then a topology discovery algorithm based on primitive protocols is presented. We also deeply study some routing protocols such as OSPF and BGP and propose a routing-protocols-based algorithm for topology discovery.

The invention relates to a node marking method in a wireless Mesh network, including that a first node transmits connection request information; a second node returns to connection response information or selects an undistributed correlation sign to mark the connection relation and return to one connection response information; the first node judges whether the correlation sign is conflicted with a distributed correlation sign or not, if yes, then retransmitting is carried out; the first node or the second node transmits information to a correspondent node; the correspondent node searches a corresponding transmitting node from a local record according to the analyzed MAC address and searches a Mesh node mark; by judging according to the mark, if no bit position is corresponding to the Mesh node mark or the corresponding bit position is set as 'no', which means that no data is transmitted to the correspondent node; otherwise, data is transmitted to the correspondent node.

本发明涉及无线Mesh网络中的节点标识方法，包括第一节点发送连接请求消息；第二节点返回连接响应消息，或者选择一个未分配的关联标志来标识连接关系，返回一个连接响应消息，第一节点判断关联标志与已分配的关联标志是否冲突，如是则重新发送；第一或第二节点向对端节点发送消息；对端节点根据解析出的MAC地址从本地记录中查找对应的发送节点，并查找Mesh节点标识；根据标识进行判断，若没有与Mesh节点标识对应的比特位或对应的比特位设置为&否&，则表示没有要发送给对端节点的数据；否则表示有。
