System Specifications:

 

Parking Meter:

 

The parking meter should be able to:

  • Successfully determine the presence or absence of a vehicle

  • Create packets containing all status parameters of the parking meter

  • Receive packets containing status information from other parking meters

  • Combine information from multiple meters into a single packet

  • Switch between ad-hoc and infrastructure modes

  • Transmit packets to a distance of at least ten meters

  • Efficiently route packets to their destination

  • Deliver packets from any point in the city to the central station in less than 10 minutes

Parking Meter Sub-Network:

 

A parking meter sub-network is a group of parking meters within proximity of each other, and will combine their information before sending it to the access point. A Sub-Network should be able to:

  • Recover from loss of a parking meter in the network

  • Recover from loss of an access point in the network

  • Recover from temporary disturbances in the network due to physical obstructions

  • Re-Integrate a meter into the network after it has been repaired

  • Create fragments if a meter or group of meter within a sub-network gets cut off from the others

  • Distinguish between packets that are internal and external to the group

  • Maintain one meter designated to communicate with the access point at any given time and fairly rotate this position within the sub-network

Central Station:

 

A computer at the central station should be able to:

  • Decode packets from the parking meters

  • Display locations and possibly pictures of illegally parked cars

  • Display locations of free parking spots

  • Display locations of non-functional parking meters and access points

  • Display network statistics such as how many packets were lost and where the losses took place
