Embodiment Construction

[0046] The present invention will be further described in detail below with reference to the embodiments, but the protection scope of the present invention is not limited thereto.

[0047] The present invention relates to an energy-aware opportunistic routing control method oriented to a mobile nano-network, which comprises the following steps.

[0048] Step 1: Nano node initialization processing, the node serial number is centered on the sink node, and decreases to the surrounding.

[0049] The step 1 includes the following steps:

[0050] Step 1.1: If the network life cycle is over, exit the control, otherwise, go to the next step;

[0051] Step 1.2: The sink node continues for a time period T 1 For the interval, send a probe packet;

[0052] In the step 1.2, the detection packet includes a sequence number, the TTL of the detection packet is 1, and the type is T. d .

[0053] Step 1.3: The nano-nodes continue to capture energy, and the serial numbers of the nano-nodes i...

Abstract

The invention relates to an energy perception opportunity routing control method for a mobile nano network. After initialization, node serial numbers are decreased progressively to the periphery by taking the aggregation node as the center; a data packet is sent to an aggregation node by taking any nano node as a starting point; and after candidate node selection is carried out, when residual energy is enough to send a data packet and receive confirmation information, the data packet is perceived and forwarded, the candidate node successfully returning ACK is used as a new nano node, and transmission to the next nano node is continued until the data packet reaches the aggregation node. The method is efficient and reliable, the direction of the aggregation node is judged according to the serial number, and the transmission reliability is improved by the candidate nodes, so that the randomly moving nano nodes accurately and reliably forward the data packet, the problem of data packet transmission failure is reduced, and the transmission efficiency is improved; the nano node forwards the data packet under the condition of sufficient energy, the concept of opportunity routing is introduced, and the broadcast characteristics of the wireless network is fully used, thereby effectively improving the performance of the mobile nano network.

Description

technical field [0001] The invention relates to the technical field of communication routing or communication path search, in particular to an energy-aware opportunistic routing control method for mobile nano-networks. Background technique [0002] With the development of nano-network routing protocols, many routing protocols have been proposed in nano-networks in different application scenarios, such as for material and environmental industrial monitoring, medical early detection or prevention of chronic diseases, etc. Currently, most nano-routing protocols The protocols are only suitable for static application scenarios, and there are few nano-routing protocols suitable for mobile scenarios; in many application scenarios of nano-networks, nodes in the network inevitably move due to external forces, and the movement of nodes will cause Many issues, such as increased packet loss, terahertz channel quality changing over time, and dynamic changes in network topology, have faci...
