MTC中继的负载均衡动态资源分配
Load Balanced Dynamic Resource Allocation for MTC Relay
摘要：
针对传统移动机器类通信（MTC）中继中频谱资源分配不公平的问题，提出了一种负载均衡中继算法（LBRA）。为了获得频谱资源的合理使用和均衡的MTC设备（MTCD）分布，频谱资源由在MTCD到MTC网关链路上重新分组的MTCD动态分配。此外，系统中断概率和传输容量的推导时，使用LBRA。仿真结果表明，该算法在传输容量和中断概率方面都优于传统方法。LBRA的传输容量增加了约0.7dB，在高MTCD密度下中断概率改善了约0.8dB。
英文摘要：
A Load Balancing Relay Algorithm (LBRA) was proposed to solve the unfair spectrum resource allocation in the traditional mobile MTC relay. In order to obtain reasonable use of spectrum resources, and a balanced MTC devices (MTCDs) distribution, spectrum resources are dynamically allocated by MTCDs regrouped on the MTCD to MTC gateway link. Moreover, the system outage probability and transmission capacity are derived when using LBRA. The numerical results show that the proposed algorithm has better performance in transmission capacity and outage probability than the traditional method. LBRA had an increase in transmission capacity of about 0.7dB, and an improvement in outage probability of about 0.8dB with a high MTCD density.
