異構(gòu)融合網(wǎng)絡(luò)聯(lián)合資源分配算法研究
[Abstract]:In the future, the communication network will realize heterogeneous integration of multiple access networks, co-exist and complement each other, cooperate with each other, and support terminal multi-host transmission and service difference. In heterogeneous converged networks, the heterogeneity of access networks, the difference of terminal performance and the diversity of service requirements will bring severe difficulties and challenges to the resource management of heterogeneous networks. This paper mainly focuses on the joint resource allocation algorithm of heterogeneous fusion network, including the following aspects: first, analyze and summarize the existing heterogeneous fusion network scenarios, wireless resource management architecture and methods, The difficulties and challenges faced by heterogeneous fusion network resource allocation algorithms are proposed, and the resource allocation algorithms such as bandwidth allocation, power allocation and joint power and bandwidth allocation in heterogeneous fusion networks are summarized. The necessity of research on joint resource allocation algorithm is put forward. Secondly, a general mobile communication system / wireless local area network (WLAN) fusion network joint resource allocation algorithm for service quality of service (Quality of Service, QoS) is proposed. For the service users with different QoS requirements, the throughput performance of users in the two networks is analyzed and evaluated, and the problem of maximizing the total throughput of users under QoS constraints is modeled. The optimal resource allocation strategy is obtained by solving the optimization problem by genetic algorithm. Numerical simulation results verify the effectiveness of the proposed algorithm. Finally, a joint resource allocation algorithm for Macro-Femto heterogeneous networks based on energy efficiency optimization is proposed to solve the problem of resource allocation in macro cell (Macro) and home cell (Femto) cellular heterogeneous networks using mixed spectrum. Considering the interference limitation, terminal energy efficiency and QoS demand factors, the energy efficiency model of macro cell user (Macrocell User Equipments, MUEs) and home cell user (Femtocell User Equipments,FUEs is modeled with channel model. Under the condition of satisfying the interference threshold and user QoS constraint, the multi-objective optimization model is modeled with the goal of maximizing the energy efficiency of users in heterogeneous networks, and the optimal joint resource allocation strategy is obtained by solving the optimization problem by using the ideal point method. Simulation results show that the proposed algorithm can achieve user energy efficiency optimization while ensuring MUEs and FUEs QoS requirements.
