In this paper, we propose a neighbor stability-based VANET clustering (NSVC) that can efficiently deliver data in urban vehicular environments. The salient features of urban vehicles are their high mobility and unpredictable direction of movement, so vehicle-to-vehicle and vehicle-to-infrastructure (V2X) communication should take into consideration the(More)
This paper focuses on a wireless solution for vehicular infrastructure systems. In order to achieve both low cost and high efficiency, infrastructures can be connected to each other in vehicular networks by a wireless link similar to a mesh router in wireless mesh networks (WMNs). However, the existing WMN solutions cannot appropriately support various(More)
The huge demand for high data rate machine-to-machine (M2M) services has led to the use of millimeter Wave (mmWave) band communications with support for a multi-Gbps data rate through the use of directional antennas. However, unnecessary sector switching in multicast transmissions with directional antennas results in a long delay, and consequently a low(More)
In capillary machine-to-machine (M2M) communications, which is being considered as a feasible network solution for M2M applications, because of physical resource constraints and deployment conditions, an energy-efficient and scalable medium access control (MAC) protocol is crucial for numerous M2M devices to concurrently access wireless channels. Therefore,(More)
This paper presents a flexible and scalable network simulation framework (FS-IIoTSim) for performance evaluation of the Industrial Internet of Things (IIoT) system. FS-IIoTSim provides flexibility and scalability for performance analysis of the IIoT system by supporting not only existing legacy industrial sensor network communication models, but also user(More)
