Self-adaptive deflection routing control method for electromagnetic nano network

Abstract

The invention relates to a self-adaptive deflection routing control method for an electromagnetic nano network. The nano node selects a next-hop nano node according to the routing table information, and deflects the data packet to other nano nodes according to the deflection routing table under the unreachable condition, so that the successful transmission probability of the data packet is increased, the nano node predicts the energy state of the next-hop nano node, and the next-hop nano node is forwarded only when the energy is enough, and the successful transmission probability of the data packet is improved; and the nano node obtains information from the acknowledgement frame fed back by the next-hop nano node to update the self routing table and the deflection routing table, so that the aim of dynamically adapting to the network load and the node energy change is fulfilled, and the performance of the network is improved. The method is simple, routing control can be carried out in aself-adaptive mode, the packet loss rate of the data packets is reduced, the nodes can update routing tables of the nodes in a self-adaptive mode according to the received feedback information, and therefore the purpose of self-adapting to network loads and energy changes of the nano nodes is achieved, and the performance of the nano network is effectively improved.

Description

technical field [0001] The invention relates to the technical field of communication routing or communication path search, in particular to an electromagnetic nano network-oriented self-adaptive deflection routing control method. Background technique [0002] With the development of nanotechnology, nanosensors with more characteristics have been developed more and more, such as nanobiosensors used to detect pathogens, nanobiosensors used for living organisms, etc., due to the relationship between their size , Compared with traditional sensors, nanosensors have higher accuracy. The extremely small size of a single nanosensor makes its computing, storage, and energy resources very limited. Therefore, in general, a large number of nanosensors are formed into a network to overcome these problems and form new systems and applications, such as targeted drug delivery. system, agricultural crop monitoring system, food safety control system, etc. [0003] At present, there are main...
