Описание:By scheduling the sensing activity we mean when to activate a sensor node for sensing and when to keep it idle (sleep mode). Information coverage, on the other hand, exploits cooperation among multiple sensors to accurately sense a point even if that point falls outside the physical coverage range of all the sensors. In the physical coverage approach, a point is said to be covered by a sensor node if that point lies within the physical coverage range (or the sensing radius) of that sensor, which is the maximum distance between the sensor and the point up to which the sensor can sense with acceptable accuracy. In particular, we are concerned with energy efficient algorithms for scheduling the sensing activity of sensor nodes. In this work, we address the question of how to schedule the activity of various sensor nodes in the network to enhance network lifetime using information coverage. The novel approach we adopt in this work to achieve efficient scheduling of sensing activity is an information coverage approach, rather than the widely adopted physical coverage approach. Focus in this work is on the efficient use of energy for sensing.

Real-Time Concepts for Embedded Systems

Chapter 11: Timer and Timer Services 11.1 Introduction In embedded systems, system tasks and user tasks often schedule and perform activities after some time has elapsed. For example, a RTOS scheduler must perform a context switch of a preset time interval periodically-among tasks of equal priorities-to ensure execution fairness when conducting a round-robin scheduling algorithm. A software-based memory refresh mechanism must refresh the dynamic memory every so often or data loss will occur. In embedded networking devices, various communication protocols schedule activities for data retransmission and protocol recovery. The target monitor software sends system information to the host-based analysis tool periodically to provide system-timing diagrams for visualization and debugging. In any case, embedded applications need to schedule future events. Scheduling future activities is accomplished through timers using timer services. Timers are an integral part of many real-time embedded systems. A timer is the scheduling of an event according to a predefined time value in the future, similar to setting an alarm clock ...»
