“…The DDBP mechanism was proposed [10] to operate at the medium access control level of IEEE 802.15.4 networks, operating in slotted and beacon-enabled mode during Contention Access Periods. DDBP is a distributed implementation of Distance-Based Priority (DBP) heuristic, which was introduced by Hamdaoui and Ramanathan [11].…”

The IEEE 802.15.4 standard proposes a flexible communication solution for Low-Rate Wireless Personal Area Networks, including Wireless Sensor Networks. In these networks, the transmission of messages or the Guaranteed Time Slot allocation are coordinated by the traditional CSMA/CA scheme, which does not provide any additional traffic differentiation mechanism. In a previous work, we proposed an approach that assigns priorities to the messages based on the (m,k)-firm task model. This paper proposes, in a complementary way, an experimental assessment in order to define the best parameters for messages prioritization. The experimental assessment considers a realistic scenario in which a set of sensor nodes, implementing the proposed scheme works in the same coverage area of another set of nodes that does not belong to the same Wireless Sensor Networks infrastructure.

Resumo-Este artigo introduz uma política de escalonamento de GTSs a fluxos de mensagens de tempo real aplicados a redes IEEE 802.15.4. O modelo nomeado (s,t)-slot garante que ao menos s fluxos de mensagens serão servidos durante um intervalo de tempo t × BI (Beacon Intervals), utilizando um teste de escalonabilidade dinâmico. A avaliação da proposta apresentada, conduzida experimentalmente, indica a factibilidade de sua implementação em nodos sensores compatíveis com o padrão IEEE 802.15.4. Analiticamente demonstra-se a adequação da proposta com o algoritmo de escalonamento EDF, o qual permite garantir requisitos de QoS, diferentemente da política FIFO originalmente oferecida por este padrão.

Generally, various traffic requirements in wireless sensor network are mostly dependent on specific application types, that is, eventdriven, continuous, and query-driven types. In these applications, real-time delivery is one of the important research challenges. However, due to harsh networking environment around a node, many researchers usually take different approach from conventional networks. In order to discuss and analyze the advantage or disadvantage of these approaches, some comprehensive survey literatures were published; however they are either out of date or compiled for communication protocols on single layer. Based on this deficiency, in this paper, we present the up-to-date research approaches and discuss the important features related to real-time communications in wireless sensor networks. As for grouping, we categorize the approaches into hard, soft, and firm real-time model. Furthermore, in all these categories, research has been focused on MAC and scheduling and routing according to research area or objective in second level. Finally, the article also suggests potential directions for future research in the field.
