Research And Implementation Of Networked Resource Sharing Mechanism Of Heterogeneous Multi-port Aggregation

With the rapid development of communication technology,a large number of wireless communication technologies born in different application scenarios have been emerging.The rapid development of mobile Internet causes that a single type of network can not meet the growing business needs of users.With the popularity of multi-frequency and multi-mode terminals,using multi-port terminal in the heterogeneous network environment covered by different standard networks to provide users with quicker and more efficient services with Qo S guarantees through the integration of heterogeneous networks has become the main direction of the development of wireless communication systems.This paper proposes a networked resource sharing architecture of heterogeneous multi-port aggregation based on the analysis of the characteristics and shortcomings of the existing heterogeneous converged network architectures.In this architecture,with the networking capabilities of the multi-mode terminal,All the nodes in the network form an Ad-hoc network,and each node in the network can access the Internet resources with other gateway by single-hop or multi-hop,which ensure that the nodes also with the LTE port in the heterogeneous network can always transmite data through the LTE and WLAN simultaneously.Through the architecture of heterogeneous multi-port aggregation,The user terminals are organically combined to take full advantage of different types of terminal nodes and different standard network collaboration capabilities,which provides users with highspeed services.In order to implement the network resource sharing architecture proposed in this paper,this article also designs and implements the routing and gateway selection algorithm,which is sensitive to the topology changes of the heterogeneous network and can also maintain the interconnection between the terminal nodes in real time and an optimal Internet gateway for each terminal node,and ensure that each node can access the Internet through the WLAN.With the multi-connection feature of the multi-mode terminal in the network architecture,a resource sharing scheme of concurrent transmission through two networks is designed and implemented at the application layer.With the server program and the browser's agent,each terminal node can simultaneously access the resources of the Internet through LTE and WLAN,which is completely transparent to the user.Finally,the effectiveness and network performance of the networked resource sharing scheme are tested.The influence of the gateway message on the network performance and the hop count of the gateway node on the throughput,delay and packet loss rate of the terminal node are mainly tested.By accessing online video through the resource sharing program in the browser via the multi-mode terminal,it could be seen that the rate is significant improved compared to a single network.Even the node is far away from the base station which is out of the coverage of WIFI,it can also connected to the Internet by multihop,and still has the advantages of transmission rate through LTE and WLAN,which proves the validity and superiority of the networked resource sharing architecture proposed in this paper,and provides support for the deep integration of heterogeneous networks in 5G networks.
