System and method for communicating over an 802.15.4 network

摘要

A method of reducing data transfer while increasing image information over an 802.15.4 network includes obtaining an image with a sensor, modulating a representation of the image using a first 802.15.4 modem, sending the representation of the image to a coordinator, demodulating the representation of the image using a second 802.15.4 modem, and digitally enhancing at least one of the representation of the image and the image. A system for communication over an 802.15.4 network includes a sensor for obtaining data, the size of the data being at least an order of magnitude greater than the size of an 802.15.4 packet, a first 802.15.4 modem coupled to the sensor, a buffer for temporarily storing the data to allow transmission of portions of the data; the buffer being coupled to the sensor, a coordinator coupled to the sensor, the coordinator being capable of communicating with a computer, and a second 802.15.4 modem coupled to the coordinator.

1. A method comprising:
obtaining an image with a camera, the image comprising data of a size in bytes at least an order of magnitude greater than the size in bytes of an 802.15.4 packet; buffering a representation of the image; transmitting 802.15.4 packet-sized portions of the representation of the image from the camera over the 802.15.4 network; obtaining a second image with the camera, the second image comprising data of a size in bytes at least an order of magnitude greater than the size in bytes of an 802.15.4 packet; buffering a representation of the second image; transmitting 802.15.4 packet-sized portions of the representation of the second image from the camera over the 802.15.4 network; comparing at least a portion of the data associated with the first image and at least a portion of the data associated with the second image; and based at least in part on the comparison, learning a pattern of events.
