“…Si bien el protocolo CoAP puede operar también en redes inalámbricas de sensores, las características del protocolo MQTT-SN diseñado específicamente para redes sensores inalámbricas le permiten trabajar de manera más óptima directamente sobre la capa de enlace, en [24] se mencionan algunas ventajas de la utilización de MQTT-SN en comparación de CoAP en redes inalámbricas de sensores por lo que tomando como base está característica, en la Tabla 1 se presenta una arquitectura de referencia para la red sensor inalámbrica con topología lineal. El proceso de la validación de la propuesta, requiere varias fases, la primera consiste en que los procesos requeridos para el enrutamiento sean realizados a nivel de enlace, en la actualidad se han realizado varias implementaciones básicas [19] [25] en las cuales se han implementado algunos de estos procesos para operar directamente con el nivel de enlace, una vez implementado y validado el funcionamiento óptimo de esos procesos, la segunda fase es la implementación del protocolo MQTT-SN sobre el protocolo 802.15.4.…”

A particular case of wireless sensor networks are those that have a linear topology. These networks are used in monitoring large-scale linear infrastructures that are characterized by having thousands of sensor nodes, hundreds of hops and great lengths. The requirements for routing in linear topologies are minimal relative to the requirements of other topologies. There are currently several network architectures and routing protocols for wireless sensor networks, which have been created based on the application that will run on the nodes. Routing protocols designed for mesh, tree, and star topologies are very complex when applied to linear multi-hop topologies, resulting in large processing delays. This article defines the relevance of the existence of the network level in the network architecture with linear topology, for which the functions of the network protocols that are applicable to linear topologies are analyzed. Finally, it is justified that the network level is not necessary in wireless sensor networks with linear topology, and as a consequence, the network levels that the new network architecture should have are proposed.

“…In [115], the authors have found that MQTT outperforms CoAP in terms of delay, the number of messages lost and the number of bytes used in messages. In [116], the authors evaluated the performance of CoAP and MQTT-SN and determined that MQTT-SN outperforms CoAP. In [118], the author compared the performance of AMQP and MQTT and have found that AMQP slightly outperforms the MQTT and CoAP protocols.…”

As the number of Internet of Things (IoT) devices proliferates, the magnitude and velocity of data continues to increase rapidly. IoT systems rely primarily on using messaging protocols for exchanging IoT data and there exists several protocols or frameworks that support distinct types of messaging patterns. Given that IoT devices typically have limited computational resources and processing power, choosing a lightweight, reliable, scalable, interoperable, extensible and secure messaging protocol becomes a very challenging task. As a result, it is not uncommon that IoT systems may employ multiple messaging protocols for supporting device heterogeneity and different message exchange patterns. In addition, basic similarities among existing several messaging protocols or frameworks that exist today for exchanging IoT data within IoT systems suggest the potential of interoperability. Given that IoT systems help facilitate the interconnectivity among distributed, heterogeneous entities, interoperability among existing messaging protocols will play an increasingly important role in simplifying the development and deployment of IoT systems. In this paper, we present a comprehensive review of the existing messaging protocols that can be used in deploying IoT systems. Throughout this paper, we highlight the protocols' distinctive approaches and applicability of using them across various IoT environments. In addition, we highlight challenges, strengths and weaknesses of these messaging protocols in the context of IoT.

“…The only difference in the architecture is that MQTT_SN needs a gateway that translate all MQTT_SN messages over UDP to MQTT messages over TCP. Currently, brokers have this functionality integrated [33]. As MQTT-SN requires broker for their communication interpretation, therefore, it needs infrastructure environment having more complexity and power consumption.…”

In this research, scalable framework for Smart Logistics based Cyber-Physical System (SLCPS) is emulated for stable coverage and connectivity of Internet of Things (IoT) devices. This work is modern manifestation of three laws of computing. Moore's and Koomey's laws recommend performance gain and energy efficiency whereas Metcalfe's law imply network scalability. Combination of these laws suggests the research proposition that development of scalable and performance efficient IoT networks is inevitable. Although IoT has improved specific logistics modules considerably, but incorporation of IoT in complete supply chain of food and random placement of IoT devices due to which unstable coverage and connectivity occurred are major challenges in logistics. The proposed SLCPS framework is designed firstly, to develop apt IoT protocol stack for logistics. Secondly, for bonded connectivity and coverage, mathematical models are proposed instead of random placement and coverage map is based on binary coverage model. Thirdly, for scalability supply chain of food for smart logistics process is designed in terms of container, storehouse and warehouse comprising of varying number of IoT devices. The architecture of SLCPS framework has three modules i.e. internal IoT network, border router and external network, emulated in Cooja simulator. The contikimac protocol is used for efficient traffic flow and power consumption. Single hop, multiple hops and random IoT devices placement scenarios are used for results comparison and validation. The performance evaluation results, i.e. throughput, network convergence time, packet delivery ratio, average latency, power consumption and timeline investigation validated utilization of proposed framework in terms of enhanced network performance. Significance of proposed SLCPS framework results in cost minimization, reducing communication and computation overhead, resilience to IoT device failures and an interference free network connectivity and coverage. Coverage and connectivity are measure of quality of service in IoT network. Therefore, this research provided bonded coverage and connectivity in smart logistics using mathematical models. In addition, a baseline framework is provided for extended research in CPS and IoT applications.
