IrisNet: An Architecture for Compute-Intensive Wide-Area Sensor Network Services

摘要: Previous work on sensor networks has targeted ad hoc wireless of closely-colocated, resourceconstrained scalar motes. Such overlooked richer types such as webcams and microphones, which are typically attached to Internetconnected machines with significant computing power storage. In this paper, we describe IrisNet (Internetscale Resource-Intensive Sensor Network services), an architecture for wide-area based these more capable sensing nodes. provides a common, scalable software infrastructure that enables the flexible creation sensor-based Internet services. It dramatically reduces network bandwidth utilization through use senselets, binary code fragments perform intensive data filtering at nodes, leveraging available processing memory. employs two-tier hierarchy nodes query Key features include partitioning, efficient protected sharing low-latency queries, partial match caching, query-specified freshness tolerances, monitoring logging support. This paper reports experiments working prototype running parking space finder service, demonstrating effectiveness IrisNet’s in achieving scalability reducing response times.
