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-f010: Message sequence chart for D2D deallocation initiated by a device.

Mentions: On receipt of a beacon frame containing a D2D descriptor corresponding to Source DevAddr and Destination DevAddr and a start slot equal to zero, source device and destination device immediately stop using the D2D period. The MLME of devices then notifies the next higher layer of the deallocation using the MLME-D2D.indication primitive with a D2DCharacteristics parameter containing the characteristics of the deallocated D2D and a Characteristics Type field set to zero. Figure 10 shows the message flow for the cases in which a D2D deallocation is initiated by a device.
