Description:
BACKGROUND OF THE INVENTION

This invention relates to systems and methods for communicating object detection data over wireless networks.

SUMMARY

Disclosed herein is a communication method comprising the steps of: (a) receiving object of interest detection data from a sensor that is operatively coupled to a first computer node in a wireless network of Unix-like computer nodes; (b) transforming the object of interest detection data into an informational payload of a ping packet; and (c) propagating the payload via echo-replies and echo-requests to all computer nodes in the network.

BRIEF DESCRIPTION OF THE DRAWINGS

Throughout the several views, like elements are referenced using like references. The figures are not drawn to scale.

FIG. 1 shows a wireless network of computer nodes.

FIG. 2 is a flowchart of one embodiment of the DAPICS method.

Abstract:
A communication method comprising the steps of: a) receiving object of interest detection data from a sensor that is operatively coupled to a first computer node in a wireless network of Unix-like computer nodes; b) transforming the object of interest detection data into an informational payload of a ping packet; and c) propagating the payload via echo-replies and echo-requests to all computer nodes in the network.
Claims:
The invention claimed is:

1. A communication method comprising the steps of: a) receiving object of interest detection data from a sensor that is operatively coupled to a first computer node in a wireless network of computer nodes, wherein each computer node has an operating system that behaves in a manner consistent with the Single UNIX.RTM. Specification; b) transforming the object of interest detection data into an informational payload of a ping packet using a -p[pattern] option to include the payload in the ping packet; and c) propagating the payload via echo-replies and echo-requests to all computer nodes in the network, wherein the ping packet is archived in each computer node in an archive file with an ICMP packet capture utility, wherein the propagating further comprises the steps of: i) transmitting a first echo request including the payload from the first computer node to a designated computer node; ii) receiving and archiving the first echo-request at all compu . . . .
