“…Por lo anterior, el manejo eficiente de las variables que determinan el tamaño de la supertrama en una transmisión de datos es fundamental y entre menos retransmisiones se hagan, menor será el consumo de energía. cadenas de Markov, se pueden encontrar en [9] y [13][14][15]. Una conclusión similar presenta [6]; mediante simulaciones encuentra que entre mayor sea el valor de BO con respecto a un valor de SO=0, la latencia es mayor.…”

ResumenLas redes de sensores inalámbricas (WSN) se están extendiendo a muchos campos de aplicación, tales como ciudades inteligentes, ambientes inteligentes, internet de las cosas, entre otras tecnologías. Para muchas de estas tendencias es esencial establecer métodos para la entrega de paquetes, sobre todo aquellos que presenten garantías de tiempo real. En este trabajo se presenta un estudio de los avances recientes publicados en la literatura científica, considerando principalmente las técnicas de acceso al medio y la planificación de transmisión de datos con garantías de tiempo real en WSN basadas en el estándar IEEE 802.15.4. Este estudio presenta las características más importantes, así como las principales diferencias entre las distintas técnicas. Al final se presentan algunas conclusiones y se proponen futuras líneas de investigación que buscan con interés la aplicación de WSN en ambientes con restricciones de tiempo real.

“…In [11], a similar analysis is proposed for WBSNs, with a particular emphasis on the radio activity of the node. The works in [17] and [18] focus on the part of the IEEE 802.15.4 standard that works in TDMA mode, and propose two separate techniques to estimate the expected packet delay. However, none of the aforementioned network models propose an in-depth analysis of the application executed by the nodes, which is crucial to have a coherent global evaluation of the WSN.…”

Wireless sensor networks (WNSs) are gradually evolving from a promising technology to a well-established reality in a large set of different domains. In order to fulfill the requirements of the specific scenario, a WSN must provide the right tradeoff between performance and lifetime, which is heavily determined by the network design. However, although the complexity of WSNs is increasing, the design space exploration is often carried out manually without the support of a general analytical methodology. In this paper, we advocate a model-based approach as an efficient and scalable way to explore the energy-performance tradeoffs during the design. In particular, we show that it is possible to define systemlevel models to describe wide classes of WSNs, providing a quick and accurate network evaluation. As a proof of concept, we propose a general model that describes the main characteristics of a class of WSNs for human health monitoring, and we apply it to a real case study. The results show that the energy-performance estimation error of the model never exceeds 1.74% compared to real data, while the evaluation time is reduced by up to 6 orders of magnitude with respect to an accurate network simulation.

The challenge of the IEEE 802.15.4 beacon-enabled mode is how to improve throughput and bandwidth utilization in contention access period (CAP) and contention free period (CFP), respectively. This article proposes a scheme to improve IEEE 802.15.4 medium access control, called superframe duration adjustment scheme (SUDAS), which analyzes the overall of the IEEE 802.15.4 not only CAP but also CFP. SUDAS is expected to effectively allocate guaranteed time slot to the requested devices, it adjusts the length of the slot in superframe duration based on the length of the packet data. This article also presents a comprehensive Markov chain analysis for SUDAS, especially for star topology, to predict the probability of successful transmission, network goodput, average bandwidth utilization, as well as total network energy consumption. The validity of the analytical model is proven by closely matching the simulation experiments. SUDAS performs better than other algorithms in terms of the probability of successful packet transmission, network goodput, average bandwidth utilization, and total energy consumption.
