Problems solved by technology

This kind of control information seriously wastes expensive wireless bandwidth and limited device energy in mobile Ad Hoc networks, especially in large-scale networks, because the average length of the route will be longer, so the load of the data packet header limits the source Scalability of Routing Protocols
At present, there is no relevant research to reduce the load introduced by the complete routing information in the DSR protocol packet header.

Embodiment Construction

[0012] In the present invention, the redundant address information carried in the routing option in the data packet header is deleted during the data transmission process, and only the routing information related to the forwarded data packet is retained. Specifically, when the intermediate node receives a data packet and then goes down Before one-hop forwarding, delete the node's own address information in the source route in the data packet header.

[0013] Solve the problem that the routing information cannot be learned and the RERR (Route ERRor) packet cannot be returned due to the DRA technology. That is, if this route is used for the first time during the transmission of the data packet, the DRA technology will not be used, that is to say, the data packet is forwarded in the same way as before the improvement, and the complete route is sent to the destination node, so that the intermediate node You can learn the lost routing information and add it to your own routing cach...

Abstract

The invention discloses a method for reducing dynamic source routing protocol controlling load. The method is realized by the following main step: in the process of forwarding multi-hops destination nodes of a data packet, redundant node address information in source routing information of the data packet is deleted so as to reduce control load which is in the data packet and is introduced by a source routing method. The method can effectively reduce the control load in DSR routing protocol, and improve data transmission rate, delaying and other performances of the routing protocol.

Description

technical field [0001] The invention relates to a power heterogeneous point wireless mobile self-organizing network Ad Hoc network, in particular to a method for reducing the control load of a dynamic source routing protocol. Background technique [0002] DSR (Dynamic Source Routing, dynamic source routing protocol) is an Ad Hoc network on-demand routing protocol using source routing ideas proposed by the Monarch working group of Carnegie Mellon University in the United States. Nodes using DSR only maintain the routing information that is being communicated, and do not use periodic routing information broadcasts to update routing information. When a node needs a route to a destination node, the node dynamically selects a route from the route cache or discovers a new route through the route discovery process; when the node finds that the link with a neighbor node fails, through The routing maintenance process completes routing switching. Source routing is a routing mechanis...
