本文将安全感知的节能资源分配问题模型化为一个分式规划问题，该问题适用于异质多宿网络。将安全感知资源分配问题描述为满足平均分组时延、平均分组丢弃概率和总可用功率消耗的保密能量效率最大化问题。为了保证分组级别的服务质量，首先将每个移动终端在链路层的平均分组时延和平均分组丢弃概率要求转化为物理层的最小保密率约束。然后，通过上图表示将非凸保密性能量效率最大化问题近似化为一个凸问题。在此基础上，利用对偶分解方法和二段搜索法，提出了一种安全感知的节能资源分配算法。最后，提出了一种启发式安全感知资源分配算法作为基准。仿真结果表明，所提出的安全感知的节能资源分配算法不仅提高了系统的保密性、能量效率和吞吐量，而且保证了分组级别的服务质量。
In this paper, a security-aware energy-efficient resource allocation is modeled as a fractional programming problem for heterogeneous multi-homing networks. The security-aware resource allocation is formulated as a secrecy energy efficiency maximization problem subject to the average packet delay, the average packet dropping probability, and the total available power consumption. In order to guarantee the packet-level quality of service (QoS), first, the average packet delay and the average packet dropping probability requirement for each mobile terminal at the link layer are transformed into a minimum secrecy rate constraint at the physical layer. Then, the non-convex secrecy energy efficiency maximization problem is approximated by a convex problem through epigraph representation. A security-aware energy-efficient resource allocation algorithm is then proposed leveraging dual-decomposition method and bi-section search method. Finally, a heuristic security-aware resource allocation algorithm is proposed to serve as a benchmark. Simulation results demonstrate that the proposed security-aware energy-efficient resource allocation algorithm not only improves the secrecy energy efficiency and throughput, but also guarantees the packet-level QoS.
