Competitive time division multiple access method of simultaneous transmission of multiple voices in wireless ad hoc network

Abstract

The invention belongs to the technical field of wireless transmission, and discloses a competitive time division multiple access method of simultaneous transmission of multiple voices in a wireless adhoc network. The method comprises the following steps: all nodes are powered on to enter perform initial network access at first; then, the nodes enter a service transmission state, and each node independently maintains the same service frame; when a service packet to be transmitted by a certain node reaches a competition threshold, the node initiates dynamic voice time slot competition, and sends the data service packet by using the competed voice time slot in the case of competition success, until the service is lower than the competition threshold or a voice service comes; and when a certain node has the voice service, the node initiates a voice service reservation process, and the node sends the data service packet in the voice time slot after the reservation is successful, until thevoice service is sent or a node with higher priority performs voice service reservation. By adoption of the competitive time division multiple access method disclosed by the invention, the delay requirements and the quality of service requirements of the delay sensitive services can be guaranteed, the system transmission efficiency is improved, and the transmission user experience is enhanced.

Description

technical field [0001] The invention belongs to the technical field of wireless transmission, and more specifically relates to a contention-type time-division multiple access method for simultaneous interpretation of multiple voices in a wireless ad hoc network. Background technique [0002] A wireless ad hoc network is a reconfigurable multi-hop wireless network that is not supported by a predetermined infrastructure. After more than ten years of continuous development, wireless ad hoc networks have undergone a revolutionary transformation from military use to civilian use, and from basic research to commercial applications. At present, the wireless self-organizing network has developed into an indispensable and important part of the new generation of wireless communication system, and it is one of the important research fields in the cutting-edge technology of my country's national medium and long-term scientific and technological development plan (2006-2020). . Wireless ...

AI Technical Summary

Problems solved by technology

However, at present, most of the domestic ad hoc network radio stations need to be designed with equal-length time slots due to the need to consider the support for frequency hopping. Directly using the reservation mechanism of the FPRP protocol will cause a huge waste of transmission resources and cannot achieve expected result

At the same time, due to the use of competition to make reservations, the delay and service quality requirements of voice services cannot be guaranteed
