Continua a série de encontros para apresentação de resultados dos projectos em curso no CISTER – uma das mais avançadas unidades de investigação mundial em sistemas computacionais de tempo real.
RESUMO The use of wireless sensor networks for real-time applications requires bounded end-to-end communication latency. Packet scheduling methods for multi-hop networks, where nodes exchange messages to construct conflict-free schedules, have been reported previously in the literature. Such methods, however, have been found to be prohibitively expensive for resource constrained wireless sensor networks. In this talk, we present logical hexagonal topology based wireless ad-hoc and sensor networks and discuss its features in the context of real-time applications. We describe a distributed algorithm that forms hexagonal backbone in an arbitrary but sufficiently dense WSN deployment.
