Problems solved by technology

[0003] Most of the existing network coding technologies adopt the strategy of encoding all intermediate nodes. The encoding of data packets by intermediate nodes not only consumes computing resources but also consumes a certain amount of energy and causes a certain delay. The encoding of intermediate nodes will greatly reduce the overall Network Transmission Efficiency

Abstract

The invention discloses a high-speed mobile ad hoc network data transmission method based on dynamic network codes. The data transmission method comprises the following steps of using link survival time and node energy as a link quality evaluation criterion to establish and choose a route, establishing a route cache table, coding data packets at source nodes according to route establishing situations, and deciding that middle nodes code and transmit received data packets or directly transmit the received data packets according to the positions of the middle nodes in current network topology. The data transmission method can choose the most stable route to transmit data through a link quality prediction mechanism, and then whether the middle nodes are coded according to the real-time positions of the middle nodes in topology of a mobile ad hoc network is decided. Compared with a method coding all middle nodes, the data transmission method guarantees reliable data transmission, reduces time delay and total energy consumption and achieves high-efficiency data transmission in a high-speed mobile ad hoc network.

Description

technical field [0001] The invention relates to the technical field of mobile ad hoc network communication, in particular to a method for realizing efficient and reliable data transmission in a high-speed mobile ad hoc network by using a dynamic network coding technology. Background technique [0002] In a traditional computer network, the intermediate node (router or switch) of the transmission network adopts a store-and-forward strategy for the received data packets without any processing on the data packets. However, the data packets transmitted in the network are essentially continuous bit streams, which are a set of abstract algebraic symbols. In theory, there is the possibility of performing algebraic operations on them, so it is possible for nodes to understand the data received on multiple links. Carry out certain linear or non-linear operations (encoding) on ​​the data packets, and then send them out. On the destination node, the information sent by the source can b...
