LIMOS: a tiny real-time micro-kernel for wireless objects

LIMOS : un micro noyau temps réel léger pour les objets sans fil


TinyOS is a natural event-driven single-task system. It fits for the single-task specific-application but not for the real-time multi-task application; while, SDREAM is a typical distributed real-time micro-kernel. It supports realtime multi-task applications but normally consumes more resources. This paper presents a novel hybrid real-time micro-kernel: LIMOS (LIghtweight Multi-threading Operating System), which combines the features of TinyOS and SDREAM. LIMOS adopts the event & thread two-level architecture and correspondingly has a two-level scheduling policy: event-driven' (high level scheduling for events) and priority-based preemptive' (low level scheduling for threads). LIMOS adopts the LINDA concept: tuple space and IN & OUT primitive-pair for system synchronization &communication. At present, LIMOS has been applied into a wireless application with the integration of multi-wireless techniques (RFID, ZigBee, and WiFi).
