Abstract

Wireless ad hoc networking enhancements are disclosed to enable deployment of networks with greater coverage. Analysis is provided which examines the environment and structures in which the wireless network operates and identifies location to place additional access points. Spanning network coverage may be computed along with the identification of coverage holes and hot spots for areas of busy communications.

Claims

1. A method comprising:

determining an area of interest for deployment of a wireless ad hoc network;

dividing the area of interest into a plurality of segments and forming a model for each of the plurality of segments, the model including one or more aggregate properties for wireless signal propagation through a corresponding one of the plurality of segments;

analyzing the area of interest using the model for each one of the plurality of segments to determine a quality of coverage by the wireless ad hoc network at one or more locations within the area of interest;

placing a wireless access point within a region of the area of interest where the quality of coverage falls beneath a predetermined threshold; and

transmitting data across the wireless ad hoc network using the wireless access point.

2. The method of claim 1 wherein the model comprises information on one or more of street furniture, height plans, clutter limits, foliage, and rooftop diffraction.

3. The method of claim 1 wherein the analyzing comprises planning street level interactions between nodes in the wireless ad hoc network in one of the plurality of segments.

4. The method of claim 1 wherein the analyzing comprises computing spanning network connectivity.

5. The method of claim 1 wherein the analyzing comprises Monte Carlo analysis of the quality of coverage.

6. The method of claim 1 further comprising analyzing the quality of coverage based on the wireless access point which was placed.

7. The method of claim 1 wherein the model comprises information on one or more of demographics, usage, and spectrum availability.

8. The method of claim 1 wherein the placing of the wireless access point is accomplished by forming a grid of multiple grid sections;

searching within each of the multiple grid sections for a possible placement of the wireless access point; and

placing the wireless access point within one of the multiple grid sections.

9. The method of claim 8 wherein a search box is formed at a center of one of the multiple grid sections and the wireless access point is placed in the search box.

10. The method of claim 9 wherein the multiple grid sections correspond to the plurality of segments.

11. The method of claim 8 further comprising validating the wireless ad hoc network within one of the plurality of segments wherein validating comprises modifying the model for the one of the plurality of segments and analyzing the model which was modified for the quality of coverage.

12. The method of claim 11 wherein the modifying the model comprises one or more of modifying grid parameters, modifying wireless access point placement, and deforming radio frequency propagation.

13. The method of claim 11 wherein the validating further comprises quantifying a number of additional wireless access points needed to reach the quality of coverage which was previously calculated during the analyzing.

14. The method of claim 1 wherein the wireless access point is placed within a search box where the search box is centered at a location of greatest coverage need.

15. The method of claim 1 further comprising analyzing the model for one of the plurality of segments based on mobile wireless access points within the one of the plurality of segments.

16. The method of claim 15 wherein the analyzing further comprises computing spanning network connectivity considering the presence of the mobile wireless access points and one or more of routes for the mobile wireless access points and density of the mobile wireless access points.

17. A computer program product embodied in a computer readable medium that, when executed, analyzes wireless communication by performing the steps of:

determining an area of interest for deployment of a wireless ad hoc network;

dividing the area of interest into a plurality of segments and forming a model for each of the plurality of segments, the model including one or more aggregate properties for wireless signal propagation through a corresponding one of the plurality of segments;

analyzing the area of interest using the model for each one of the plurality of segments to determine a quality of coverage by the wireless ad hoc network at one or more locations within the area of interest; and

evaluating placement for a wireless access point within a region of the area of interest where the quality of coverage falls beneath a predetermined threshold.

24. The computer program product of claim 17 wherein the evaluating placement of the wireless access point is accomplished by forming a grid of multiple grid sections;

searching within each of the multiple grid sections for a possible placement of the wireless access point; and

placing the wireless access point within one of the multiple grid sections.

18-23. -23. (canceled)

25-32. -32. (canceled)

33. A system for analyzing wireless communication comprising:

a processor configured to;

determine an area of interest for deployment of a wireless ad hoc network;

divide the area of interest into a plurality of segments and form a model for each of the plurality of segments, the model including one or more aggregate properties for wireless signal propagation through a corresponding one of the plurality of segments;

analyze the area of interest using the model for each one of the plurality of segments to determine a quality of coverage by the wireless ad hoc network at one or more locations within the area of interest; and

evaluate placement for a wireless access point within a region of the area of interest where the quality of coverage falls beneath a predetermined threshold; and
