摘要

物联网(IoT)已成为一个有趣的研究领域,因为在不同的应用领域,如智能医疗和工业领域,部署了大量设备(最好配备传感器、通信和执行器模块)来捕捉实时数据。这些设备具有与物理现象直接交互的内置能力,可在各自的覆盖范围内报告任何异常情况,例如,在智能医院中监测危重病人,但与共同目标模块的直接通信却无法保证,如果两个或更多设备(最好是距离较近的设备)有兴趣同时传输数据,则可能非常具有挑战性。因此,在本手稿中,我们将介绍一种混合时隙分配方法,该方法专为那些居住在邻近地区并渴望与共同目标设备(即服务器)同时通信的设备而设计。一开始,我们使用 k-mean 聚类算法将这些设备分组,服务器被迫从部署在各自覆盖区域内的设备收集数据。因此,每个服务器都会为活动设备生成专用插槽,并为服务器生成额外的插槽。同样,建议的邻区分时多路存取(TDMA)可以灵活地为请求设备分配多个可用时隙,这在现场虫害检测等场景中是必需的。此外,还允许成员设备从一个服务器的覆盖区域迁移到另一个服务器的覆盖区域(如果需要和可能的话)。仿真结果证实,建议的方法优于现有算法(机会式 TDMA、混合 TDMA 和非正交多址接入),特别是在带宽、端到端延迟和空时利用率方面。拟议方案提高了带宽和空时隙利用率,分别约为 15%和 12%,同时实现了约 94.89% 的可用时隙利用率,而之前的利用率为 93.4%。

Device-enabled neighborhood-slot allocation for the edge-oriented Internet of Things
Internet of Things (IoT) has become an interesting research domain as numerous devices, preferably equipped with sensors, communication, and actuator modules, are deployed to capture real-time data in the different application areas, such as smart healthcare and industries. These devices have the built-in capacity to directly interact with the physical phenomenon and report any unusual situation within their respective coverage areas, i.e., monitoring a critical patient in the smart hospital but direct communication with a common destination module is not guaranteed and could possibly be very challenging if two or more devices, preferably those in closed proximity, are interested to transmit simultaneously. Therefore, in this manuscript, we are going to present a hybrid slot allocation approach, which is specifically designed for those devices resided in neighborhood and are eager to communication concurrently with a common destination device, i.e., server. In the beginning, the k-mean clustering algorithm is used to group these devices into clusters where server is forced to collect data from devices deployed in the respective coverage areas. Thus, every server generates dedicated slots for active devices and an additional slot for server(s). Similarly, the proposed neighborhood-enabled time division multiple access (TDMA) has the flexibility of assigning multiple slots to a requesting device if available, which is needed in scenarios, such as detection of pest in the field. Additionally, a member device is allowed to migrate (if needed and possible) from one server's coverage region to another. Simulation results confirmed that the proposed approach is better than the existing algorithms (opportunistic TDMA, hybrid TDMA, and non-orthogonal multiple access), particularly in terms of bandwidth, end-to-end delay, and empty slot utilization. The proposed scheme has improved bandwidth and empty slot utilization, which are approximately 15% and 12%, respectively, whereas it has achieved approximately 94.89% utilization of the available slots which was previously 93.4%.
