Patent Images
1. A system comprising:
- a first plurality of sensor nodes distributed in a first parking area to detect the presence of vehicles in parking spaces the first parking area, wherein the sensors transmits detection information wirelessly;
a first bridge node in the first parking area, wirelessly coupled to the first plurality of sensors;
a first plurality of display nodes in the first parking area, wirelessly coupled to the first bridge node, wherein each display node provides an indication of where open parking spaces are located in the first parking area; and
a first gateway node, wirelessly coupled to the first bridge node and an administrative console to control operation of the system.

Abstract
A parking guidance system tracks available parking spaces and leads users to vacant spots through display boards placed at strategic locations in the parking lot. Sensor nodes are deployed at parking spaces or within traffic lanes to monitor parking space occupancy and wirelessly transmit this information. The sensor nodes form a wireless network that routes the knowledge of available spaces to the corresponding display boards and updates them in real time. Parking availability information may also be shared with users in a variety of other ways such as through the Internet, personal digital assistants, computers, mobile telephones, in-vehicle dashboards, and others.

7. A method comprising:
-
using a first sensor node, detecting whether a vehicle is present in a first parking space of first parking area;
from the first sensor node, wirelessly transmitting information on whether the first parking space is occupied to a bridge node; and
updating a display to reflect whether the first parking space is occupied or unoccupied based on the information received by the bridge node. - View Dependent Claims (8, 9, 10, 11, 12, 13)
