ABSTRACT
The Internet of things (IoT) is a novel paradigm where all things or objects in daily life can communicate with other devices and provide services over the Internet. Things or objects need identifying, sensing, networking and processing capabilities to make the IoT paradigm a reality. The IEEE 802.15.4 standard is one of the main communication protocols proposed for the IoT. The IEEE 802.15.4 standard provides the guaranteed time slot (GTS) mechanism that supports the quality of service (QoS) for the real-time data transmission. In spite of some QoS features in IEEE 802.15.4 standard, the problem of end-to-end delay still remains. In order to solve this problem, we propose a cooperative medium access scheme (MAC) protocol for real-time data transmission. We also evaluate the performance of the proposed scheme through simulation. The simulation results demonstrate that the proposed scheme can improve the network performance.

sensors-15-11628-f015: The throughput as a function of the average SNR.

Mentions: Figure 15 shows the throughput as a function of the average SNR. As shown in Figure 15, the proposed scheme provides a higher throughput than both the IEEE 802.15.4 standard and ESS scheme for all SNR values. This is because the proposed scheme can select the link with the better link quality. The throughput of the ESS scheme and IEEE 802.15.4 standard is influenced more by the SNR since they have to transmit and receive data frame through the fixed link.
