Need Information to create GeoFence

[engr.humair]

Hi Friends,

I am working on Vehicle Tracking & Security system Project. Can anyone guide me on the following issues:

1. How to create Geo-Fence (What concepts & formulas will be used)?

I am using PIC16F876A MCU on hardware side & VB6 on Software side

2. Is it better to GeoFence on Software or Hardware side?

Thanks,
Engr. Humair

Depends - if you want to use diameter around a single point as a GeoFence it can be implemented in this PIC MCU, but if you want to use area with complex shape as a GeoFence it will be better to implement it in the server side, because you have to use polar coordinates calculations and it will be too big task for the PIC. In this case you have to send the current position let say every 30 sec. and the server can take care of the complex calculations.
