Real-Time Issues in Wireless Sensor Networks
Chenyang Lu · 2005
Many mission-critical applications require wireless sensor networks to interact with physical environments under stringent timing constraints and severe resource constraints. Examples include intruder tracking, medical care, fire monitoring, and structural health monitoring. This tutorial presents our research on a range of real-time issues in wireless sensor networks including (1) packet scheduling algorithms for endto-end real-time communication; (2) power management protocols for energyefficient real-time data collection; and (3) spatiotemporal query services for mobile users. This tutorial also discusses research challenges in the area of real-time wireless sensor networks.
