1. A method, comprising the step of:
- operating a wireless vehicular sensor node communicatively coupled to a magnetic sensor, comprising the steps of;
using a vehicle sensor state from said magnetic sensor to create a waveform characteristic and a vehicular waveform;
turning-on a vehicle presence based upon a rising edge in a latest of said waveform characteristics;
turning-off said vehicle presence based upon a falling edge in said latest of said waveform characteristics; and
generating a long report approximating said vehicular waveform for wireless transmission when said vehicle presence is turned on.

Abstract
This document discloses using multiple wireless vehicular sensor nodes to wirelessly receive multiple, time-interleaved vehicular waveform reports from the nodes. Each vehicular waveform report approximates a raw vehicular sensor waveform observed by a magnetic sensor at the node based upon the presence of a vehicle. The vehicular waveform reports are products of this wirelessly receiving process. The document also discloses apparatus supporting the above outlined process. The vehicular waveform reports may be time synchronized.
