Realization of Interrupts and Time Management of a Sensor Network Operating System

Abstract

μOS, the operating system of microkernel wireless sensor network, is a real-time multi-tasking operating system; and its main function modules include task management, time management, interrupt management, energy conservation mechanism and communication protocol. Thereinto, its time management and interrupt management is the basis of other functional modules. The author designs and realizes clock management and interrupt management for microkernel wireless sensor network operating system μOS. It is shown from system performance tests such the time management and interrupt management are capable of satisfying real-time requirements in the system.
