Problems solved by technology

[0006] However, due to the complexity and dynamics of multi-layer dense heterogeneous network topology and node types, existing security transmission methods are difficult to flexibly adapt to the situation of multi-layer dense heterogeneous networks, which may lead to poor energy or resource efficiency in some areas. High or insufficient safety performance in some areas

Abstract

The invention belongs to the technical field of mobile communication, and particularly relates to a multipoint cooperative physical layer secure transmission method of an intensive heterogeneous network. The multipoint cooperative physical layer secure transmission method of the intensive heterogeneous network comprises the following steps: judging whether the current network can provide inter-cluster cooperation; judging the mobility of a target user; selecting a cooperative service base station set; configuring the cooperation modes of base stations in the cooperative service base station set; and performing cooperative secure transmission on the target user. By adoption of the multipoint cooperative physical layer secure transmission method of the intensive heterogeneous network, the physical layer security of wireless transmission of the intensive heterogeneous network is improved, and the ability of the network system of defend the potential silent eavesdropping is improved.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a method for secure transmission of multi-point cooperative physical layer in a dense heterogeneous network. Background technique [0002] The popularization and performance improvement of smart terminals have promoted the rapid development of wireless data services. However, single-layer macro networks that pursue large coverage areas and homogeneous service optimization are increasingly difficult to carry exponentially increasing data traffic. The heterogeneous network formed by superimposing low-power small base stations on the coverage of macro base stations can improve the reuse rate of space resources and communication coverage. [0003] Furthermore, since there are huge differences in space and time in the distribution of the number of users and the distribution of service density, densely deploying a large number of small base stations in hotspot...
