Abstract

Objectives: To increase the data transmission between the nodes and decrease the latency in data transmission between the nodes than the traditional routing methods. Methods: A novel methodology is being proposed to increase the success rate of real-time transmission by competitively utilizing high-quality links included in different paths in real-time multi-path routing. That is, if a packet that arrives first in one path is copied and delivered to another path immediately, each path competitively delivers the packet in realtime, which has the effect of delivering the packet through a virtual real-time optimal path composed only of high-quality links can be obtained through this, the proposed method can provide a higher success rate for real-time transmission than the existing methods in an environment where link quality is variable. To achieve this goal, the proposed method consists of 1) multi-path configuration method, 2) bridge node selection method, and 3) contention realtime transmission method. Findings: Performance evaluation is performed by comparing and analyzing the experimental results of Equal-Cost Multi-Path Routing (ECMP) and PMMR (Partitioning Multi-constrained Multipath Routing) among the existing multi-path methods and various conditions of the proposed method. The proposed method obtains three results according to the latency (0, 0.05, and 0.1) of the bridge node, and independent multi-path transmission allows each path to follow a single-path routing method. Novelty : The performance of data transmission between nodes is increased and reduced the latency time by the Proposed Contention Transmission Routing Algorithm (PCTRA) when compared to ECMP and PMMR.
