A clustering routing method based on energy perception of nano network nodes

Abstract

The invention relates to a clustering routing method based on nano network node energy perception. The method comprises the following steps of broadcasting an initialization data packet on a nano gateway, after receiving the initialized data packet, enabling an aggregation node to broadcast a statistical message to count the number of associated nano-nodes and broadcasts a clustering data packet;after receiving the statistical message, enabling the associated nano node to return an acknowledgement message, enabling the aggregation node to update the initialization data packet and broadcast the initialization data packet to the next aggregation node based on the number of the neighbor nano nodes, and enabling the associated nano node to broadcast the clustering data packet to the next nanonode at the same time; and completing clustering and carrying out data transmission. According to the clustering routing method based on node energy perception, the transmission range from the nanometer node to the aggregation node can be limited to a certain extent and the transmission energy efficiency and reliability from the aggregation node to the nano gateway are improved, so that the routing method can be effectively operated in a nano network with limited node computing power and energy and high node density.

Description

technical field [0001] The invention relates to the technical field of communication routing or communication path search, in particular to a clustering routing method based on energy perception of nanometer network nodes. Background technique [0002] Nanonetwork is a new type of network composed of nanonodes—such as nanorobots, nanosensors, etc.—and various nanodevices. [0003] Nano-nodes are composed of multiple nano-units, including nano-antennas, nano-sensing units, nano-processors, etc., whose size ranges from several hundred nanometers to several microns; among them, nano-robots are also equipped with miniature cameras, miniature "fingers" , a tail for movement, etc., can flexibly complete various tasks in the human body, and because the nano-sensing node is extremely small, its monitoring of substances is more accurate, and it can complete the work that traditional sensor nodes cannot do. Due to the new characteristics of nano-nodes and nano-networks, they can be w...
