The exponential growth in mobile broadband data traffic with demand for faster data connectivity has become the most engaging challenges for mobile operators. They are facing an enormous data load in the core network and are finding new solutions to offload data to other complementary technologies. Mobile data offloading using device-to-device (D2D) communication stands out as the promising and the low-cost solution to reduce the burden on cellular network. Data offloading is the process of reducing the load in the cellular medium by using alternative wireless technologies for bearing data using opportunistic assignment of nodes. In this paper, iNHeRENT, a Novel HybRid user equipment (UE) selection scheme using D2D communication in next generation wireless networks that provides better offloading efficiency and throughput than the existing schemes, is proposed. Here, a small set of Wi-Fi-enabled hybrid user equipment (⁠|$UE_H$|*) is chosen to offload cellular data in an efficient way. The objective of the work is to use minimum number of |$UE_H$|* to cover maximum number of UE in the serving area of an evolved Node B and to offload maximum amount of data. A |$UE_H$|* is a special UE with both cellular and Wi-Fi interfaces enabled to offload data. The coverage, throughput, packet delivery ratio and offloading efficiency metrics for the selected number of |$UE_H$|* are considered, and it is found that an offloading efficiency of 95.45% was achieved for a minimum number of 7% |$UE_H$|* using iNHeRENT.

使用D2D通信的高效数据卸载的新型混合UE选择方案

随着对更快的数据连接的需求，移动宽带数据流量的指数增长已成为移动运营商最引人入胜的挑战。他们正面临着核心网络中巨大的数据负载，并且正在寻找新的解决方案来将数据卸载到其他互补技术中。使用设备到设备（D2D）通信的移动数据卸载是减轻蜂窝网络负担的有前途且低成本的解决方案。数据卸载是通过使用节点的机会性分配使用替代的无线技术来承载数据来减少蜂窝介质中的负载的过程。在本文中，iNHeRENT是一种在下一代无线网络中使用D2D通信的新型HybRid用户设备（UE）选择方案，与现有方案相比，该方案可提供更好的卸载效率和吞吐量，被提议。这里是一小部分支持Wi-Fi的混合用户设备（⁠| $ UE_H $ | *）被选择为以有效方式卸载蜂窝数据。工作的目的是使用| $ UE_H $ |的最小数量。*覆盖演进型节点B服务区域中最大数量的UE，并卸载最大数据量。A | $ UE_H $ | *是同时启用蜂窝和Wi-Fi接口以卸载数据的特殊UE。| $ UE_H $ |个选定数量的覆盖率，吞吐量，数据包传递率和卸载效率指标 *被考虑，发现最小数量为7％| $ UE_H $ |的卸载效率为95.45％。*使用iNHeRENT。
