Method, device and system for dynamic on-demand allocation of wireless ad hoc network resources

Abstract

The invention discloses a method, device and system for dynamic on-demand allocation of wireless ad hoc network resources, and relates to the field of communication technology, wherein the method applied to a common node includes receiving data packets sent from its own network layer; The sum of the cumulative data packet length of the destination node; calculate and obtain the real-time bandwidth resource requirements of different destination nodes; send bandwidth resource request information including real-time bandwidth resource demand information to the central node; judge whether to receive the new time slot resource sent by the central node Allocation table; when receiving a new time slot resource allocation table sent by the central node, perform service transmission and communication according to the new time slot resource allocation table. The present invention can evaluate the dynamic resource requirements of nodes in real time and accurately, and allocate wireless resources reasonably according to the requirements, which can improve resource utilization and allocation fairness, and have higher end-to-end service transmission service quality for resource acquisition. advantage.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for dynamically allocating resources of a wireless ad hoc network on demand, a common node device, a central node device and a wireless ad hoc network system. Background technique [0002] Wireless ad hoc network is a distributed wireless group autonomous network, no fixed infrastructure, equal node status, free movement, flexible networking, multi-hop relay, self-healing and other characteristics, in emergency deployment, Public services, military communications and other scenarios are more and more widely used. [0003] In a wireless communication system, wireless system resources mainly include frequency resources, time resources, space resources, etc. Inter-node communication and service transmission all depend on the acquisition of wireless resources. Wireless resource allocation refers to the control, management and scheduling of system resources through ce...

Problems solved by technology

The first disadvantage is that due to the lack of unified calculation and distribution, it is easy to cause excessive throughput and unbalanced load of some nodes, resulting in network congestion, high collision rate, and reduced service transmission reliability; second, distributed distribution requires independent links for each hop. Reservation and allocation of resources makes the final multi-hop delay longer, and the real-time service QoS guarantee is not enough in a multi-hop environment

However, most of the current centralized allocation methods cannot respond to the resource requirements of nodes in a timely manner, so that resource allocation cannot support business transmission requirements in real time, resulting in low resource utilization.
