Embodiment Construction

[0043] The present invention uses the MATLAB platform to simulate and analyze the AR-TORA-FCS adaptive repair method proposed by the present invention. The protocol of the present invention is compared with the classic TORA protocol, the proposed TORA-p protocol and the TORA-MPR protocol. The average end-to-end delay between nodes, the delivery rate of data packets, and the routing topology control overhead are carried out at different node data packet sending rates, different node moving speeds, different network node numbers, and link failure rates. simulation analysis. See attached figure 1 , the specific implementation process is detailed as follows:

[0044] Step 1. Mathematical model establishment:

[0045] Step 1.1. Establish an optimization formula

[0046] Definition 1. Self-healing node: In any data transmission path of DAG in TORA routing, if the link fails at a certain time, causing the path to fail, the node with a larger height value of the faulty link is cal...

Abstract

The invention provides a TORA protocol self-adaptive restoration method based on a flooding control mechanism, and belongs to the field of mobile Internet of Things, and the method comprises the steps: firstly converting a self-restoration process of a self-restoration node in a DAG of TORA into an optimal searching problem of an optimal node, and building a formula; and according to a Ray-Algorithm search result, proving that the search result is an optimal solution of an optimal node search process; giving a condition algorithm for judging self-repairing, determining a condition threshold value initiated in the self-repairing process, carrying out path repairing before path failure, and providing an algorithm for determining an optimization area. Simulation and experiment results show that the algorithm improves the average end-to-end delay, reduces the control overhead, and improves the packet delivery rate of data packets.

Description

technical field [0001] The invention belongs to the field of the mobile internet of things, and in particular relates to an adaptive repair method of the TORA protocol based on a flood control mechanism. Background technique [0002] The development of the communication network not only requires the realization of high-speed data transmission, but also the ability to flexibly build the network topology according to the actual situation, and has the ability to survive. MANET is a self-organizing, reconfigurable multi-hop wireless network that does not depend on infrastructure. Compared with traditional wireless networks, it has the characteristics of temporary establishment, dynamic topology change, low cost, and limited node capacity. In the rescue and disaster relief environment, the communication between the scattered nodes is realized by MANET. In the MANET network, the mobility of nodes and the limitation of communication distance make data transmission more complicate...
