RAP: A Real-Time Communication Architecture for Large-Scale Wireless Sensor Networks

Chenyang Lu, Brian Blum, Tarek Abdelzaher, John Stankovic & Tian He
Large-scale wireless sensor networks represent a new generation of real-time embedded systems with significantly different communication constraints from traditional networked systems. This paper presents RAP, a new real-time communication architecture for large-scale sensor networks. RAP provides convenient, high-level query and event services for distributed micro-sensing applications. Novel location-addressed communication models are supported by a scalable and light-weight network stack. We present and evaluate a new packet scheduling policy called velocity monotonic scheduling that inherently accounts...
