Intelligent Channel Allocation for Age of Information Optimization in Internet of Medical Things

Abstract

Along with the development of realtime applications, the freshness of information becomes significant because the overdue information is worthless and useless and even harmful to the right judgement of system. Therefore, The Age of Information (AoI) used for marking the freshness of information is proposed. In Internet of Medical Things (IoMT), which is derived from the requirement of Internet of Thins (IoT) in medicine, high freshness of medical information should be guaranteed. In this paper, we introduce the AoI of medical information when allocating channels for users in IoMT. Due to the advantages of Deep Q-learning Network (DQN) applied in resource management in wireless network, we propose a novel DQN-based Channel Allocation (DQCA) algorithm to provide the strategy for channel allocation under the optimization of the system cost considering the AoI and energy consumption of coordinator nodes. Unlike the traditional centralized channel allocation methods, the DQCA algorithm is distributed as each user performs the DQN process separately. The simulation results show that our proposed DQCA algorithm is superior to Greedy algorithm and Q-learning algorithm in terms of the average AoI, average energy consumption and system cost.

Research on Humanistic Quality Higher Medical Education Based on Internet of Things and Intelligent Computing

“…Due to the lack of teachers' investment, curriculum arrangement, and teaching equipment, students spend most of their time studying professional courses. Wei et al's research [ 22 ] shows that under the background of diversified socialist values, humanistic quality higher medical education is seriously affected by bad social atmosphere, such as money worship, hedonism, extreme individualism, and some corruption. The value orientation of medical students is somewhat deficient, and humanistic quality education is ignored, and understanding is vague.…”

Three-Way Group Decisions with Incomplete Spherical Fuzzy Information for Treating Parkinson’s Disease Using IoMT Devices

“…Recently, many scholars have conducted meaningful researches on IoMT. For instance, Wei et al [6] proposed an intelligent channel allocation algorithm in the context of IoMT. Jain et al [7] explored the combination of IoMT with point-of-care testing devices to monitor infectious diseases.…”
