Device to device (D2D) communication that provides high data rate proximity based direct communication between users, along with simultaneous wireless information and power transfer (SWIPT) that extracts energy from the received RF power, can achieve high energy and spectral efficiencies together with low latency communication. Heterogeneous networks, that employ efficient frequency reuse, provide high gains in the coverage and capacity of the cellular networks. SWIPT helps in converting the harmful interference, incurred by the frequency reuse of D2D tier underlaying the Hetnet, into energy that can be stored for the future. This work presents a resource allocation and power control scheme for SWIPT enabled underlay D2D networks, designed to improve the energy efficiency and the amount of energy harvested while ensuring the minimum required data rates for the users. Resource allocation is performed using a stable many-to-one matching game model inspired from Gale-Shapley algorithm. Two techniques of SWIPT, namely power splitting SWIPT and time splitting SWIPT, are considered and the resource allocation schemes are designed for both. Simulation results demonstrate the superior performance of the proposed algorithm compared to an existing work in single tier network with power splitting SWIPT. The work is extended to a typical 5G HetNet scenario, and extensive simulations are done to compare the performance of the two SWIPT architectures in the HetNet scenario.

设备到设备（D2D）通信可在用户之间提供基于高数据速率接近度的直接通信，同时从接收到的RF功率中提取能量的同时进行无线信息和功率传输（SWIPT），可实现高能量和频谱效率以及低延迟通讯。采用有效的频率复用的异构网络在蜂窝网络的覆盖范围和容量方面提供了很高的收益。SWIPT有助于将构成Hetnet底层的D2D层的频率复用所产生的有害干扰转换为可以存储的能量。这项工作提出了启用SWIPT的底层D2D网络的资源分配和功率控制方案，旨在提高能源效率和收集的能量数量，同时确保为用户提供最低要求的数据速率。资源分配是使用受Gale-Shapley算法启发的稳定的多对一匹配游戏模型进行的。考虑了SWIPT的两种技术，即功率分配SWIPT和时间分配SWIPT，并为两者设计了资源分配方案。仿真结果表明，与具有功率分配SWIPT的单层网络中的现有工作相比，该算法具有更高的性能。这项工作已扩展到典型的5G HetNet场景，并且进行了广泛的仿真以比较HetNet场景中两种SWIPT架构的性能。资源分配是使用受Gale-Shapley算法启发的稳定的多对一匹配游戏模型进行的。考虑了SWIPT的两种技术，即功率分配SWIPT和时间分配SWIPT，并为两者设计了资源分配方案。仿真结果表明，与具有功率分配SWIPT的单层网络中的现有工作相比，该算法具有更高的性能。这项工作已扩展到典型的5G HetNet场景，并且进行了广泛的仿真以比较HetNet场景中两种SWIPT架构的性能。资源分配是使用受Gale-Shapley算法启发的稳定的多对一匹配游戏模型进行的。考虑了SWIPT的两种技术，即功率分配SWIPT和时间分配SWIPT，并为两者设计了资源分配方案。仿真结果表明，与具有功率分配SWIPT的单层网络中的现有工作相比，该算法具有更高的性能。这项工作已扩展到典型的5G HetNet场景，并且进行了广泛的仿真以比较HetNet场景中两种SWIPT架构的性能。仿真结果表明，与具有功率分配SWIPT的单层网络中的现有工作相比，该算法具有更高的性能。这项工作已扩展到典型的5G HetNet场景，并且进行了广泛的仿真以比较HetNet场景中两种SWIPT架构的性能。仿真结果表明，与具有功率分配SWIPT的单层网络中的现有工作相比，该算法具有更高的性能。这项工作已扩展到典型的5G HetNet场景，并且进行了广泛的仿真以比较HetNet场景中两种SWIPT架构的性能。
