A data transmission method and system for a mobile ad hoc network

Abstract

The invention discloses a data transmission method and system of a mobile Ad Hoc network. The data transmission method includes the following steps: aggregating the nodes of the whole network according to the mutual distance between the nodes to form several cluster groups, and in each cluster group Establish the upper-same-lower cluster group membership information starting from each cluster head; when a certain cluster group in the network receives data packets, the cluster head receives the data, according to the cluster group membership information and the empty packet queue According to the cluster group membership, the data is transmitted to the terminal node through the next level or the same level node. The present invention establishes the mobile Ad Hoc network cluster group membership information, and performs data forwarding and processing according to the membership relationship, so that the data packet The number of forwarding and processing nodes is greatly reduced, saving time and improving efficiency.

Description

technical field [0001] The invention relates to the field of data processing of AdHoc networks in wireless networks, in particular to a data transmission method and system of mobile AdHoc networks. Background technique [0002] At present, mobile AdHoc network applications are gradually emerging. Various mobile terminals or nodes that support wireless applications, such as smart phones, mobile computers, smart readers, and wireless routers, can be automatically organized into application networks to provide resource sharing and various applications in the mobile environment. Serve. In this environment, mobile terminals can send messages, transmit ordinary text, and even transmit and share multimedia data (video, voice, etc.) online. However, since the mobile AdHoc network is a kind of wireless ad hoc network, unlike the Internet network with relatively fixed equipment, in this network, each communication node is mobile, locally gathered, and may be caused by the suddenness ...

Problems solved by technology

QOLSR extends OLSR and designs from multi-metric QoS standards such as bandwidth and delay, but it cannot guarantee that the route with the largest bandwidth and the shortest delay can be selected, and the node is in a neighbor node based on one hop or two hops Selecting the best nodes to form the MPR, so that the process of forming the best route costs too much time, and the efficiency of data transmission is also greatly affected.
