“…The achieved simulation results showed that the enhanced RPL outperforms the native RPL in terms of end-to-end delay, throughput, packet delivery rate and power consumption. A simulation based study of the feasibility of visual data transmission over the standard RPL is presented in [26]. By focusing on the impact of radio duty cycling on the received video quality as well as the network consumed energy, simulation results mainly showed that RPL along with ContikiMAC can not support realtime…”

“…Due to the high rate video traffic that characterizes multimedia applications, we have used the null radio duty cycle (Nullrdc) mechanism on the Contiki OS MAC layer because it makes nodes to be awake all the time in order to receive and transmit video packets. Moreover, it has been proven in [26], that RPL under ContikiMAC can not handle realtime video transmission. However, to overcome the inefficiency of power consumption caused by this Nullrdc driver, harvesting energy mechanisms can be integrated at network nodes in order to balance the trade-off between quality of transmissions and the limited resources of WMSNs [5,6,50].…”

“…In addition, these studies use multipath as a mechanism for forwarding data, relying mainly on the available list of parents of each node of the DODAG. On the other hand, few work [23][24][25][26] have been done on video transmission over RPL utilizing only a single path, none of them suggested the use of multiple paths in order to handle video traffic. According to our knowledge, this is the first work that studies the feasibility of transmitting video traffic over LLN based WMSN by using the multipath RPL routing at the same time.…”

Internet of Multimedia Things (IoMT), a special subset of Internet of Things (IoT), is a novel paradigm which is progressively increasing and gaining in popularity, allowing many multimedia content based applications such as Wireless Multimedia Sensor Networks (WMSNs). The standard IPv6 Routing Protocol for Low power and Lossy Networks (RPL), originally designed for transmitting scalar data traffic of IoT applications, should be customized in order to deal with IoMT applications which pose new challenges and requirements in terms of the Quality of Service (QoS) and the user's Quality of Experience (QoE). For this purpose and thanks to the flexibility and adaptability of RPL, we propose, in this paper, a multipath version of RPL, not defined in the RPL specification RFC 6550, named MP-RPL. MP-RPL leverages the multiparent feature offered by RPL in order to construct multiples end-to-end paths of different qualities based on radio link quality measurements. It is intended to improve the video traffic delivery for IoMT based WMSN applications by simultaneously using the built paths while taking into account the video traffic differentiation as per priority levels. Compared to the traditional single-path RPL, the results obtained from simulations when considering the influence of video characteristics, show that our proposal provides feasible and acceptable QoS and QoE performance metrics for multimedia applications, while maintaining RPL compliance.

“…Notwithstanding the fact that RPL almost meets the requirements of LLNs to support scalar data transport, it remains difficult to handle real time streaming of video clips since it was mainly targeted to low data rate applications [14]. To allow for multimedia transport, new objective functions based on energy [4,27] or free bandwidth [8] have been proposed.…”

RPL is the IETF standardized IPv6 Routing Protocol for Lowpower and lossy networks (LLNs). The major effort is therefore made on handling low data rate traffic. Meanwhile, the Internet of Multimedia Things (IoMT) emerged as one hot topic of the Internet of Things (IoT). In LLNs, providing a descent quality of service (QoS) along with a user quality of experience (QoE) for multimedia applications is challenging. High bandwidth and significant computation capabilities are necessary while LLNs are very resource constrained. To raise the available bandwidth to accommodate high data rate applications, we propose to simultaneously transmit a flow on multiple disjoint paths. To do so, we exploit the DODAG structure, already maintained by RPL, to build disjoint paths without incurring extra overhead. To reduce the amount of data to send while considering the low computation resources of video sensors, we propose to apply a priority-based low-complexity encoding scheme on the captured pictures. Highest priority data can be replicated on more than one path. Our conducted experiments using simulations as well as a real testbed show that the best QoS and QoE are obtained when multiple paths are used along with the replication of highest priority data packets.

“…Such a Cloud-Fog-Edge architecture provides the processing support needed by the IoHT constrained devices. This way, IoHT technologies can contribute to improve performance, reduce costs and mitigate risk [12][13][14][15][16][17]. However, although the IoHT have been adopted to monitor people everywhere, there is a place where technology must be much more efficient due to its inherent criticality: the hospital.…”

Due to the non-stop and rapid spreading of virus pandemics all over the world, traditional healthcare monitoring capabilities of hospitals and/or medical centers are under a severe over-load. Modern computing infrastructures with the harmony of various layers of computing paradigms (e.g., cloud/fog/edge computing) for healthcare monitoring are apparently the essential computing backbone that help access and process instantly the medical data of every single patient at the very edge of the healthcare system to combat with global or regional virus contagion. Previous studies proposed different computing system architectures for healthcare monitoring but few works considered the evaluation of pure performance of medical data transmission in a comprehensive manner. In this paper, we proposed an M/M/c/K queuing network model for the performance evaluation of an Internet of Healthcare Things (IoHT) infrastructure in association with a three layer cloud/fog/edge computing continuum. The model considers a life cycle of medical data from body-attached IoT sensors in edge layer all the way to local clients (e.g., local medical doctors, physicians) through fog layer and to remote clients (e.g., medical professionals, patient's family members) through cloud layer. Furthermore, we also explore the impact of the alteration in system configuration and computing capability of computing layers in two scenarios on various performance metrics. Critical performance metrics related to quality of service are evaluated in a comprehensive manner, such as (i) mean response time of medical data transmission to fog (local) clients and to cloud (remote) clients, (ii) utilization of cloud/fog/edge computing layers, (iii) service throughput, (iv) number of medical messages in a period of time, and (v) drop rate. The simulation results pinpoint bottle-neck parameters and configurations of the IoHT infrastructure's system architecture in relation to the frequency of medical data collection for health check of patients. Thus, the findings of this study can help improve medical administration in hospitals and healthcare centers and help design computing infrastructures in accordance for medical monitoring in the severe circumstances of virus pandemics.
