Abstract

The invention relates to the router design and research field of the mobile wireless self-organized network, which is more particularly characterized by including the flowing steps sequentially: the initial TTL values of the IP messages sent by all nodes are set to be 64. When the node sends an IP message, a router stored to a target IP is only sent to a next corresponding hop, or floods the messages to all the neighbors. When the node receives the IP message, the retransmitting hop times passed by the message can be analyzed according to the current TTL value of the message, and the shortest path to the source can be determined by combining the corresponding routing items of the node. The non-shortest routing produced in the process of flooding can be deleted for overtime as no corresponding IP message is transmitted. The invention realizes a novel rapid and simple Ad Hoc path-finding method with low protocol bandwidth consumption.

Description

technical field

[0001] The method of ad hoc network path finding based on point-by-point decision-making of data packets belongs to the research field of mobile wireless ad hoc network routing. Background technique

[0002] Ad Hoc network is a wireless network that can be quickly built at any time as needed, without any infrastructure support or central management. It originally originated in the field of American military research in the 1970s. It can realize the temporary interconnection of multiple mobile terminals within a limited range, and provides a flexible interconnection method for mobile communication terminals in the local area network. At present, the Ad Hoc network is mainly used in environments such as military communication, rescue after an earthquake or water fire. In addition, Ad hoc is also very suitable for occasions requiring temporary communication such as exhibition halls, meeting rooms, gymnasiums, classrooms, and trains. It can be predicted that Ad...
