Priority-Driven MAC Protocol Design for IoT-Enabled Wireless Body Area Networks
摘要
Internet of Things (IoT)-based wireless body area networks (WBANs) have developed as a hopeful technology for enabling distant health monitoring and personalized healthcare applications. One of the key communication issues in IoT-based WBANs is the design of energy-effective medium access control (MAC) protocols that can also improve the network throughput, packet delivery ratio (PDR), and minimize the delays in data packet transmission. These performance metrics can be improved by minimizing the channel access collisions. Hence, this work proposes a priority-based mechanism to minimize channel access collisions in IoT-based WBANs. The proposed mechanism uses IEEE 802.15.4 standard MAC protocol (Baseline-MAC) superframe structure. We have used the MATLAB simulator to implement the proposed mechanism. The simulation results show that the proposed mechanism attains less energy consumption (EC) and less delay in data packet transmission as compared to Baseline-MAC.
