摘要/Abstract

摘要：

物联网中的许多设备，尤其是能量受限的传感器设备，通常缺乏高效的网络连接方式。若采用基于移动热点共享的组网方式，则可以高效实现大面积网络覆盖。该组网方式的基本思想是激励蜂窝网中的部分移动节点（如智能手机和其他智能设备的持有者）开启移动热点，为资源受限节点提供Wi-Fi连接，满足这些节点的通信需求，从而实现移动互联网的高效接入。在这种组网方式中，如何激励移动用户贡献热点是关键。主要研究移动热点共享网络中的激励机制及其对网络性能的影响，并设计了一套新颖的激励机制，使部分用户可以通过贡献Wi-Fi 热点获取一定收益。首先，研究了该激励机制下不同类型用户的最优共享决策以及不同用户之间决策的影响；然后，分析了用户行为和网络整体状态随时间的演化规律以及系统的均衡状态。仿真结果表明，在系统均衡状态下，移动热点贡献者的数量随免费流量配比的增大而增大，因此导致热点使用者数量增大。若单位流量价格过高，则使用者数量将减少，不利于网络运行。此外，与无热点共享网络相比，采用移动热点共享的组网方式可使网络性能最高提升148%。

Abstract:

Many devices in the Internet of things,especially energy-constrained sensor devices,often lack efficient network connectivity.If the networking method based on mobile hotspot sharing is adopted,large-area network coverage can be realized efficiently.The basic idea of the networking mode is to activate some mobile node in the cellular network (such as the holders of smart phones and other smart devices) to open mobile hotspot,provide Wi-Fi connections for resource-constrained node,and satisfy the communication needs of these node,so as to achieve efficient access to the mobile Internet.In this networking mode,how to encourage mobile users to contribute hotspot is the key.The incentive mechanism in mobile hotspot sharing network and the impact on network performance was studied mainly,and a novel incentive mechanism was designed to enable some users to obtain certain benefits by contributing Wi-Fi hotspot.Firstly,the optimal sharing decision of different types of users under the incentive mechanism and the influence of decision-making among different users were studied.Then,the evolution of user behavior,the overall state of the network with time and the equilibrium state of the system were analyzed.The simulation results show that under the equilibrium state of the system,the number of mobile hotspot contributors increases with the increase of free traffic ratio,which also leads to an increase in the number of hotspot.If the price of unit traffic is too high,the number of users will be reduced,which is not conducive to the operation of the network.In addition,compared with the non-hotspot sharing network,if the mobile hotspot sharing networking mode is adopted,the network performance can be increased by up to 148%.
