This work focused on the problem of finding a suitable medium access control protocol so that the nodes of a given cluster could communicate efficiently within their respective activity window. The nodes thus saved energy by turning off their transceivers during the time that they did not have to exchange information. This works main objective was to ensure that the nodes were mainly focused on energy efficiency and delivering packages, taking quality of service (QoS) requirements into account and comparing their performance to an existing protocol called sensor medium access control (S-MAC). The parameters being compared were the time that the nodes were asleep, energy consumption and average delay. This work was completed by using the OPNET simulator tool (OPNET Modeler, version 11.5.A PL3, OPNET Technologies Company Inc). This approach greatly improved the "PCF + Sleep” performance proposed in this work over the earlier S-MAC.
Este trabajo se enfoca al problema de encontrar un protocolo de acceso al medio para que los nodos de un mismo grupo puedan comunicarse eficientemente dentro de la ventana de actividad que les corresponde. De esta manera, los nodos ahorran energía mediante el apagado de su subsistema de comunicaciones durante el tiempo en que no tienen que intercambiar información. El objetivo principal de este trabajo es el de que los nodos se enfoquen principalmente en la eficiencia de energía y la entrega de paquetes que toman en cuenta requerimientos de calidad de servicio, comparando su rendimiento contra un protocolo llamado SMAC; los parámetros comparados son: el tiempo que duran dormidos los nodos, su consumo de energía y su retardo promedio. La realización de este trabajo se hizo con la herramienta de simulación OPNET Modeler versión 11.5.A PL3, de la compañía OPNET Technologies Inc. Esta técnica mejora ampliamente el desempeño "PCF + Dormir" propuesto en este trabajo, al anterior, nombrado SMAC.
