Embodiment Construction

[0087] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0088] The present invention examines a hybrid network in which a D2D network and a cellular network coexist, such as figure 1 shown. Assume that there are M cellular users in the cellular network, whose subscripts are m=1, 2,...M; the D2D network is composed of N device nodes, whose subscripts are n=1, 2,...N, and each D2D node is shared by The uplink spectrum of the cellular user performs direct communication, and a D2D communication link can only use the spectrum of one cellular user. Among the N D2D nodes, there are N ser file server, labeled These servers store the same data; among the N D2D nodes, there are also N sub subscribers, marked as These subscribers have the requirement to download the same data from the server. We consider a scenario where there are two file servers, two subscribers, and two cellular users. Since each subscriber has the same ...

Abstract

The invention discloses a routing method based on P2P file sharing in a wireless D2D network, which comprises the steps of 1) constructing a routing optimization model of the maximum average data download speed according to the path gain of a base station terminal, the signal to interference ratio of signals transmitted by cellular subscribers at the base station terminal and the highest transmission rate among nodes; and 2) designing a routing strategy which does not support a P2P file sharing mechanism in the routing optimization model, carrying out file server selection on each subscriber, then carrying out spectrum allocation on each file server, finally selecting a shortest path for each file server between the file server and the subscriber connected with the file server, and carrying out data transmission. The routing method disclosed by the invention comprehensively considers interference between A D2D node and the cellular subscriber, and satisfies the minimum transmission rate of a D2D link while ensuring the communication quality of the cellular subscribers; and the data download speed is significantly improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method for sharing routing based on P2P files in a wireless D2D network. Background technique [0002] Due to the extensive and frequent information interaction between devices in the wireless communication network, and the increasing shortage of wireless resources, D2D (device-to-device) direct communication technology has attracted widespread attention in the academic community. It not only meets the needs of direct communication between devices , can also improve the spectral efficiency and system capacity of the cellular network. In a D2D network, since the transmit power of each node is limited, it is often necessary to establish a multi-hop route to meet the requirements of reliable communication. However, the propagation rate of multi-hop communication sometimes fails to meet the requirements. On the one hand, it is because the transmission po...
