Research And Implementation Of Resource Allocation Mechanism In Wireless Ad Hoc Networks

A wireless ad hoc network is a peer-to-peer wireless mobile network consisting of a set of randomly distributed,dynamic nodes.The status of each node is equal.Each node can not only serve as a common node,but also can be used as a route for message forwarding.Therefore,when communicating with a node that is far away,communication can be performed by means of the routing function of the ordinary node.Special networks are mainly used in military communications,disaster relief,business environment and other fields.With the rapid development and popularization of communication technologies,there is an increasing shortage of wireless channel resources.The Media Access Layer(MAC)protocol is a key part of the protocol of the wireless ad hoc network.It can determine the way the node uses the channel,and the channel access and channel resource allocation of the node directly affect the performance of the wireless ad hoc network.How to design a reasonable channel resource allocation mechanism has always been a research hotspot.At present,the company's existing wireless ad hoc network project resource allocation mechanism has the disadvantages of slow networking,wasted channel resources,and low allocation efficiency.In view of these shortcomings,this paper will redesign the allocation mechanism of resource modules,that is,after collecting the topology,the combination of static allocation of resources and dynamic allocation will be used to negotiate the time slot resources of the allocated channels.Based on the static allocation of channel resources,dynamic resource allocation can periodically obtain service traffic between nodes to determine whether resource negotiation events need to be processed.Negotiation events are added in the form of registration events to the negotiation event queue.All channel resource negotiation events are managed to make the resource allocation more organized,reduce the networking time,improve the utilization of channel resources and the stability of the system of the wireless terminal device.According to the requirements analysis and design,the software is programmed.At the same time,the simulation and design of the design and implementation and the system test of the wireless terminal equipment are carried out by means of the development environment of the internship company and the company test environment.It is verified whether the design scheme can increase the bandwidth and meet the project requirements.This article provides an efficient solution based on the actual needs of the company's projects.After one year of system design and software programming,and embedded in the wireless terminal equipment system,and finally tested in the test environment built by the OPNET simulation platform and the internship company,all the indicators met the design indicators and solved the networking time.Long,low allocation efficiency,has a certain use value.
