Aggregation of Continuous Monitoring Queries in Wireless Sensor Networking Systems

摘要

In this demo paper, we introduce our sensor query aggregation system, Continuous Monitoring Query Evaluation System (CMQES), which is a test-bed for studying the aggregation problems of continuous monitoring queries (CMQ) on sensor data streams in a wireless sensor networking system. A CMQ monitors the data values from sensor nodes distributed in the system environment. The objective of CMQES is lo provide a configurable test-bed to study various important issues in aggregation of CMQ. An aggregation scheme, Sequential Pushing (SeqPush) has been implemented. Various system settings and parameters can easily be configured witli the interlace provided in C'MQIiS, and statistics such as the number of messages, complexity in processing and the energy consumption rale at the sensor nodes, are collected.
